Introduction  
Metrologic’s TECH 7 laser bar code projection scanner is encased in an  
NEMA-12 steel case. The case construction enables the scanner to operate in  
harsh surroundings, especially industrial environments. Water-resistant,  
shock-resistant, and rugged, the TECH 7 is also fast, aggressive and reliable. It  
can register bar codes at a range of 76mm - 254mm (3" - 10") and can  
autodiscriminate among all common codes.  
To suit particular applications, two different scan patterns are available: an  
omnidirectional pattern of 20 interlocking lines (Model MS770); or a 12-line  
raster pattern (Model MS775). The scanner has a VLD design, a scan speed of  
up to 2000 lines per second, and uses less than 8 watts of power.  
Other features include an Application Specific Integrated Circuit (ASIC) and  
MECCA© (Metrologic Enhanced Code Correcting Algorithm). An Application  
Specific Integrated Circuit (ASIC) is in the decoding system and virtually  
eliminates misreads. MECCA© (Metrologic Enhanced Code Correcting  
Algorithm) enables the TECH 7 scanner to read poorly printed, wrinkled or  
even torn bar codes on the first pass.

Scanner Installation  
To maintain compliance with applicable standards, all circuits connected to the  
scanner must meet the requirements for SELV (Safety Extra Low Voltage)  
according to EN 60950. To avoid potential problems, do not power up the  
scanner until the communication cable is secured to the host.  
1. "Power off" the host system.  
2. Locate the 19-pin female end of the scanner link cable and find the  
widest key located above pins L and A. Align this key with the  
corresponding key on the scanner box’s Mil spec connector. While  
pushing in on the connector, rotate the ring clockwise until it locks into  
place with a click.  
3. Connect the other end of the communication cable to the host device. (If  
the scanner is powered by the host, skip to Step 5.)  
4. Check the AC input requirements of the transformer/power supply to  
make sure the voltage matches an available AC outlet. Plug the  
transformer into the AC outlet to supply power to the scanner. (A  
socket-outlet shall be installed near the equipment and shall be easily  
accessible.)  
5. "Power up" the host system.  
Note: When the scanner first receives power, the LEDs will flash and  
then the scanner will beep once. After the scanner performs this  
startup sequence, the green LED will remain on for a specified  
time indicating that the laser is on.

Configuration to the Host System  
The scanner is shipped from the factory programmed to a set of default  
conditions noted in the ScanSelect Scanner Programming Guide by an asterisk  
that appears before the brief definition located next to the bar code.  
In order for the scanner to communicate with a host system properly, it may  
need to be programmed. Since each host system is unique, configure the  
scanner to match the host system requirements. Configure the scanner by  
entering the program mode and scanning the appropriate bar codes that appear  
in the ScanSelect Scanner Programming Guide. (To use ScanSet™, refer to  
the ScanSet documentation for information on how to configure a scanner.)  
1. Connect the scanner to the host system (Refer to the Scanner  
Connections to the Host section in this guide).  
2. Enter program mode by scanning the ENTER/EXIT program mode bar  
code. (The unit will beep three times)  
3. Scan the appropriate bar code(s) that appear in the ScanSelect Scanner  
Programming Guide. (Reveal only one bar code to the scanner each  
time. With your hand, cover the bar code not to be scanned.)  
4. Exit program mode by scanning the ENTER/EXIT program mode bar  
code again. (The new options will be saved and the scanner is ready for  
normal operation.)

Green and Red LEDs  
When the green LED is on, this  
indicates that the unit is receiving  
power and the laser is on. When the  
red LED flashes on, the scanner has  
read a bar code successfully. When the  
red light turns off, communica-tion to  
the host is complete.  
Speaker  
The speaker emits a beep when a bar  
code has been decoded.

Laser Output Window This aperture emits the laser light.  
Mil spec Connector  
The 19-pin male Mil spec connector  
was designed to connect a communi  
cation cable from the scanner to a host  
device. The communication cable may  
include a power supply or it may be de  
signed to draw power directly from the  
host device. The standard TECH 7 has  
one connector. (When atrium option is  
installed, a second connector is  
installed on the unit to connect the  
MX001 Industrial Control Interface  
box.)

Visual Indicators  
There is a red and green LED at the top of the scanner. When the scanner is  
on, the flashing or stationary activity of the LEDs indicates the status of the  
scan and scanner.  
Steady Green  
When the laser is on, the green LED is also on. This occurs when an object is  
in the scan field.  
Steady Green; Red Flash  
When the scanner successfully reads a bar code, the red LED will flash then  
beep once. If the red LED does not flash or the scanner does not beep once,  
then the bar code has not been successfully read.  
Steady Red and Green  
After a successful scan, the scanner transmits the data to the host device. When  
the host is not ready to accept the information, the scanner’s red LED will  
remain on until the data can be transmitted.  
Alternating Red and Green  
This indicates the scanner is in program mode.  
Steady Red  
This indicates the scanner is in ScanSet mode.  
No Red or Green LED  
There are two reasons why the LEDs will not be illuminated. First, if the  
scanner is receiving power and the LEDs are not on, then the scanner has  
remained dormant for a specified time and the laser has turned off. To  
reactivate the unit, touch the touch plate. Secondly, if the scanner is not  
receiving power from the host or transformer, then the LEDs will not turn on.  
Flashing Red  
This indicates the scanner has experienced a laser subsystem failure. Return  
the unit for repair at an authorized service center.

Signaux optiques  
Sur la partie supérieure du scanner se trouvent une diode LED rouge et une diode LED  
verte. Quand le scanner est sous tension, les diodes rouge et verte clignotantes ou  
allumées vous informent sur l'état du scanner.  
Ni la diode rouge, ni la diode verte n'est allumée  
Il existe deux raisons possibles pour que les diodes ne s'allument pas. Premièrement: si  
le scanner reçoit de l'énergie sans que les diodes ne s'allument, le scanner est resté sans  
servir pendant une certaine période et le laser est désactivé. Pour le réactiver, passer un  
objet devant le palpeur infrarouge. Deuxièmement: quand le scanner ne reçoit de  
l'énergie ni de l'ordinateur central, ni du transformateur, les diodes restent éteintes.  
La diode verte reste allumée  
Quand le laser est en service, la diode verte s'allume également. C'est le cas quand un  
objet se trouve devant le palpeur. La diode verte reste allumée tant que la temporisation  
de l'infrarouge dure ou jusqu'à ce que le scanner soit désactivé.  
La diode verte reste allumée; la diode rouge clignote  
Après lecture avec succès d'un code à barres par le scanner, la diode rouge se met à  
clignoter, suivie d'un bip sonore unique. Si la diode rouge ne clignote pas ou quand  
aucun bip sonore n'est émis, cela signifie que le code à barres n'a pas pu être lu avec  
succès.  
Les diodes rouges et vertes restent allumées  
Une fois la lecture effectuée avec succès, le scanner transmet les données à l'ordinateur  
central. Si ce dernier n'est pas prêt à recevoir les données, la diode rouge du scanner  
reste allumée jusqu'à ce que les données puissent être transmises.  
Les diodes rouges et vertes clignotent en alternance  
Indique que le scanner se trouve en mode de programmation.  
La diode rouge reste allumée  
Indique que le scanner se trouve en mode ScanSet.  
Diode rouge clignotante  
Indique une panne de laser pendant la lecture. Veuillez envoyer votre appareil chez  
unconcessionnaire pour réparation.

Optische Anzeigen  
Auf dem Scanner befinden sich eine rote und eine grüne Leuchtdiode. Bei  
eingeschaltetem Scanner geben Ihnen die blinkenden bzw. feststehenden  
Leuchtdiodenanzeigen Aufschluß über den Abtast- und Scannerstatus.  
Weder rote noch grüne Leuchtdiodenanzeige  
Es gibt zwei mögliche Gründe, weshalb die Leuchtdiodenanzeigen nicht aufleuchten.  
Erstens: Wenn der Scanner mit Energie versorgt wird und die Leuchtdiodenanzeigen  
nicht aufleuchten, so ist der Scanner für einen bestimmten Zeitraum untätig geblieben,  
und der Laser ist abgeschaltet. Zur Reaktivierung der Einheit sollten Sie ein Objekt vor  
dem Infrarot-Sensor hin- und herbewegen. Zweitens: Wenn der Scanner weder vom  
Hostrechner noch vom Transformator Energie erhält, so leuchten die  
Leuchtdiodenanzeigen nicht auf.  
Feststehende grüne Anzeige  
Wenn der Laser in Betrieb ist, leuchtet die grüne Leuchtdiodenanzeige ebenfalls auf.  
Dies ist dann der Fall, wenn sich ein Objekt im Abtastfeld befindet. Die grüne  
Leuchtdiodenanzeige leuchtet solange auf, bis das Infrarot-Timeout abgelaufen ist, oder  
bis der Scanner abgeschaltet wird.  
Feststehende grüne Leuchtanzeige; rote Blinkanzeige  
Nach erfolgreichem Lesen eines Barcodes durch den Scanner blinkt die rote  
Leuchtdiodenanzeige auf, gefolgt von einem einmaligen Piep-Signal. Blinkt die rote  
Leuchtdiodenanzeige nicht auf oder sendet der Scanner kein Piep-Signal aus, so konnte  
der Barcode nicht erfolgreich gelesen werden.  
Feststehende rote und grüne Leuchtanzeige  
Nach erfolgreichem Abtasten überträgt der Scanner die Daten an das Hostgerät. Falls  
das Hostgerät zur Datenannahme nicht bereit ist, leuchtet die rote Leuchtdiodenanzeige  
des Scanners solange auf, bis die Daten übertragen werden können.  
Alternierende rote und grüne Leuchtanzeige  
Zeigt an, daß sich der Scanner im Programmiermodus befindet.  
Feststehende rote Leuchtanzeige  
Zeigt an, daß sich der Scanner im ScanSet-Modus befindet.  
Aufblinkende rote Leuchtanzeige  
Zeigt an, daß beim Scanner ein Laserausfall vorliegt. Bringen Sie das Gerät zur  
Reparatur in ein Vertragsservicecenter.

Segnali ottici  
Sullo scanner si trovano due diodi luminosi: uno rosso e uno verde. Quando lo scanner  
è inserito, i diodi luminosi, che possono o essere accesi in continuazione o lampeggiare,  
Vi informano sullo stato della scansione e dell’apparecchio.  
Né il diodo luminoso rosso né quello verde sono accesi  
Vi sono due possibili cause se i diodi luminosi non sono accesi. Prima causa: se lo  
scanner viene alimentato e i diodi luminosi non sono accesi, lo scanner è rimasto  
disattivato per un determinato periodo e il laser è spento. Per riattivare l’unità dovreste  
muovere un oggetto davanti al sensore a infrarossi. Seconda causa: se lo scanner non  
viene alimentato né dal calcolatore host né dal trasformatore, i due diodi luminosi non  
sono accesi.  
Il diodo luminoso verde è acceso  
Quando il laser è inserito, è acceso anche il diodo luminoso verde. Questo si ha quando  
un oggetto si trova nella zona di scansione. Il diodo luminoso verde è acceso fino al  
raggiungimento del timeout infrarossi oppure fino allo spegnimento dello scanner.  
Il diodo luminoso verde è acceso; quello rosso lampeggia  
Dopo la lettura riuscita di un codice a barre da parte dello scanner il diodo luminoso  
rosso lampeggia e quindi viene emesso un unico segnale beep. Se il diodo luminoso  
rosso non lampeggia oppure lo scanner non emette un segnale beep, ciò significa che la  
lettura del codice a barre non è riuscita.  
Sono accesi sia il diodo luminoso rosso che quello verde  
Dopo la scansione riuscita lo scanner trasmette i dati all’host. Se l’host non è pronto per  
accettare i dati, il diodo luminoso rosso dello scanner è acceso fino a che i dati possono  
essere trasmessi.  
Il diodo luminoso rosso e quello verde sono accesi in alternanza  
Ciò indica che lo scanner si trova nella modalità di programmazione.  
Il diodo luminoso rosso è acceso  
Ciò indica che lo scanner si trova nella modalità ScanSet.  
Il diodo luminoso rosso lampeggia  
Ciò indica che lo scanner ha un guasto a livello del laser. Fate riparare l’apparecchio da  
un centro di assistenza autorizzato.

Labels  
There is one label located inside the window of the scanner noting that this  
device is a CDRH Class IIa laser product and IEC 825 LASERKLASSE 1.  
Also, on the scanner is a label located on the back of the unit. This label  
contains information such as the model number, date of manufacture, serial  
number, and approvals. The following are samples of the labels located on the  
unit.

Notices  
Notice  
This equipment has been tested and found to comply with limits for a Class A digital device,  
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection  
against harmful interference when the equipment is operated in a commercial environment. This  
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in  
accordance with the instruction manual, may cause harmful interference to radio communications.  
Operation of this equipment in a residential area is likely to cause harmful interference, in which  
case the user will be required to correct the interference at his own expense. Any unauthorized  
changes or modifications to this equipment could void the users authority to operate this device.  
Notice  
This digital apparatus does not exceed the Class A limits for radio noise emissions from digital  
apparatus set out in the Radio Interference Regulations of the Industry and Canada.  
Caution  
Use of controls or adjustments or performance of procedures other than those specified herein may  
result in hazardous laser light. Under no circumstances should the customer attempt to service the  
laser scanner. Never attempt to look at the laser beam, even if the scanner appears to be  
nonfunctional. Never open the scanner in an attempt to look into the device. Doing so could result  
in hazardous laser light exposure. The use of optical instruments with the laser equipment will  
increase eye hazard.  
Remarque  
Après contrôle de cet appareil, on a noté qu'il répondait aux valeurs limites de la classe A, c-  
onformément à la partie 15 des directives de l'administration fédérale américaine pour les t-  
élécommunications. Ces valeurs limites ont été prévues pour garantir une protection suffisante  
contre les effets nocifs dus à l'emploi de l'appareil dans un magasin. L'appareil génère et utilise une  
énergie haute fréquence et peut, s'il n'est pas installé et utilisé conformément aux instructions  
mentionnées dans le guide d'utilisation, entraîner des perturbations dans la radiocommunications.  
L'utilisation de cet appareil dans une zone d'habitation entraînera très vraisemblablement des  
perturbations. Dans ce cas, l'utilisateur est tenu de remédier à ces perturbations à ses propres frais.  
Toute modification ou remplacement non autorisé sur cet appareil peut entraîner l'invalidité de  
l'autorisation d'utilisation de l'appareil.  
Remarque  
Cet appareil numérique ne va pas contre les valeurs limites pour émissions de bruits radios des  
appareils numérique de la classe A, conformément aux directives relatives aux perturbations des  
radiocommunications du ministère canadien pour l'industrie.  
Attention  
L'emploi de commandes, réglages ou procédés autres que ceux décrits ici peut entraîner de graves  
irradiations. Le client ne doit en aucun cas essayer d'entretenir lui-même le scanner ou le laser. Ne  
regardez jamais directement le rayon laser, même si vous croyez que le scanner est inactif.  
N'ouvrez jamais le scanner pour regarder dans l'appareil. Ce faisant, vous vous exposez à une  
rayonnement laser mortel. L'emploi d'appareils optiques avec cet équipement laser augmente le  
risque d'endommagement de la vision.

Anmerkung  
Nach Überprüfung dieses Geräts wurde festgestellt, daß es den Grenzwerten für Digitalgeräte der  
Klasse A gemäß Teil 15 der Richtlinien der US-amerikanischen Bundesbehörde für das  
Fernmeldewesen entspricht. Diese Grenzwerte wurden festgelegt, um einen angemessenen Schutz  
gegen schädliche Auswirkungen bei Einsatz des Geräts in einer Ladenumgebung zu gewähren.  
Das Gerät erzeugt und verwendet Hochfrequenzenergie und kann diese ausstrahlen, und kann,  
falls es nicht gemäß den im Bedienerhandbuch enthaltenen Anweisungen installiert und verwendet  
wird, zu einer Störung des Funkverkehrs führen. Der Betrieb dieses Geräts in einem Wohngebiet  
führt höchstwahrscheinlich zu Störungen. In diesem Fall ist der Bediener verpflichtet, die Störung  
auf eigene Kosten zu beseitigen. Durch jegliche unerlaubte Auswechselung oder Änderung an  
diesem Gerät könnte die Genehmigung des Bedieners zur Verwendung dieses Geräts ungültig  
werden.  
Anmerkung  
Dieses Digitalgerät verstößt nicht gegen die Grenzwerte für Funkrauschemissionen von  
Digitalgeräten der Klasse A gemäß den Richtlinien für Funkstörungen des kanadischen  
Ministeriums für Industrie.  
Achtung  
Die Verwendung anderer als der hierin beschriebenen Steuerungen, Einstellungen oder Verfahren  
kann eine lebensgefährliche Laserstrahlung hervorrufen. Der Kunde sollte unter keinen  
Umständen versuchen, den Laser-Scanner selbst zu warten. Sehen Sie niemals in den Laserstrahl,  
selbst wenn Sie glauben, daß der Scanner nicht aktiv ist. Öffnen Sie niemals den Scanner, um in  
das Gerät hineinzusehen. Wenn Sie dies tun, können Sie sich einer lebensgefährlichen  
Laserstrahlung aussetzen. Der Einsatz optischer Geräte mit dieser Laserausrüstung erhöht das  
Risiko einer Sehschädigung.  
N.B.  
Dal controllo di questo apparecchio risulta che esso risponde ai valori limite per apparecchi  
digitali della classe A conf. parte 15 delle direttive sulle telecomunicazioni dell’Autorità federale  
statunitense. Questi valori limite sono stati fissati per garantire una protezione adeguata contro gli  
effetti nocivi se questo apparecchio viene usato all’intero di un negozio. L’apparecchio genera,  
utilizza e può emettere energia ad alta frequenza e, se non viene installato ed utilizzato  
conformemente alle indicazioni fornite nel Manuale utente, può provocare disturbi al servizio  
radiofonico. L’uso di questo apparecchio in zone residenziali causa molto probabilmente dei  
disturbi. In questo caso l’utente è obbligato ad eliminare questi disturbi a sue spese. Qualsiasi  
sostituzione o modifica non autorizzata all’apparecchio potrebbe rendere invalida l’autorizzazione  
dell’utente all’uso dell’apparecchio.  
N.B.  
Questo apparecchio digitale non supera I valori limite per l’emissione di radiorumori da parte di  
apparecchi digitali della classe A conformemente alle direttive per radiodisturbi del Ministero  
canadese per l’Industria.  
Attenzione  
L’utilizzo di sistemi di controllo, di regolazioni o di procedimenti diversi da quelli decritti nel  
presente Manuale può provocare dei raggi laser pericolosi per la vita. Il cliente non deve  
assolutamente tentare di riparare egli stesso lo scanner laser. Non guardate mai nel raggio laser,  
anche se credete che lo scanner non sia attivo. Non aprite mai lo scanner per guardare dentro  
l’apparecchio. Se tuttavia lo fate, potete esporVi a dei raggi laser pericolosi per la vita. L’uso di  
apparecchi ottici con questo equipaggiamento laser aumenta il rischio di danni alla vista.
