ABOUT WWVB RADIO CONTROLLED TIME  
The NIST (National Institute of Standards and Technology—Time and  
Frequency Division) WWVB radio station is located in Ft. Collins,  
Colorado, and transmits the exact time signal continuously throughout the  
United States at 60 kHz. The signal can be received up to 2,000 miles  
away through the internal antenna in the weather projection station.  
However, due to the nature of the Earth’s Ionosphere, reception is very  
limited during daylight hours. The wireless weather station will search for  
a signal every night when reception is best.  
BATTERY CHANGE:  
It is recommended to replace the batteries in all units on an annual basis  
to ensure optimum accuracy of these units.  
Please participate in the preservation of the  
environment. Return used batteries to an authorized  
depot.  
The WWVB radio station receives the time data from the NIST Atomic  
clock in Boulder, Colorado. A team of atomic physicists is continually  
measuring every second, of every day, to an accuracy of ten billionths of  
a second per day. These physicists have created an international  
standard, measuring a second as 9,192,631,770 vibrations of a Cesium-  
133 atom in a vacuum. For more detail, visit  
(303)499-7111. This number will connect you to an automated time,  
announced at the top of the minute in “Coordinated Universal Time”,  
which is also known as Greenwich Mean Time (GMT). This time does not  
follow Daylight Saving Time changes. After the top of the minute, a tone  
DEVICE RESET  
The Weather Station and the Thermo-hygro transmitter need to be reset

will sound for every second. It is possible that your wireless weather  
station may not be exactly on the second due to the variance in the  
quartz. However, the clock will adjust the quartz timing over the course of  
several days to be very accurate; under 0.10 seconds per day.

The icons displayed forecast the weather in terms of getting better or  
worse and not necessarily sunny or rainy as each icon indicates. For  
example, if the current weather is cloudy and the rainy icon is displayed, it  
does not mean that the product is faulty because it is not raining. It simply  
means that the air pressure has dropped and the weather is expected to  
get worse but not necessarily rainy.  
WEATHER FORECAST AND WEATHER TENDENCY:  
WEATHER FORECASTING ICONS:  
Weather icons in the third section of LCD can be displayed in any of the  
following combinations:  
Note:  
FORECAST  
FORECAST  
FORECAST  
After setting up, readings for weather forecasts should be disregarded for  
the next 48-60 hours. This will allow sufficient time for the Weather station  
to collect air pressure data at a constant altitude and therefore result in a  
more accurate forecast.  
Sunny  
Cloudy with sunny intervals  
Rainy  
Common to weather forecasting, absolute accuracy cannot be  
guaranteed. The weather forecasting feature is estimated to have an  
accuracy level of about 75% due to the varying areas the Weather station  
has been designed for use in. In areas that experience sudden changes  
in weather (for example from sunny to rain), the Weather station will be  
more accurate compared to use in areas where the weather is constant  
most of the time (for example mostly sunny).  
For every sudden or significant change in the air pressure, the weather  
icons will update accordingly to represent the change in weather. If the  
icons do not change, then it means either the air pressure has not  
changed or the change has been too slow for the Weather station to  
register. If the icon displayed is a sun or raining cloud, there will be no  
change of icon if the weather gets any better (with sunny icon) or worse  
(with rainy icon), since the icons are already at their extremes.  
31  
32  
 
If the Weather station is moved to another location significantly higher or  
lower than its initial standing point (for example from the ground floor to  
the upper floors of a house), discard the weather forecast for the next 48-  
60 hours. By doing this, the Weather Station will not mistake the new  
location as being a possible change in air-pressure when really it is due  
to the slight change of altitude.  
Note: Once the weather tendency indicator has registered a change in air  
pressure, it will remain permanently displayed on the LCD.  
AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH  
BAROMETRIC PRESSURE TREND)  
The third section of the LCD also shows the relative air pressure value  
and the air pressure history.  
WEATHER TENDENCY INDICATOR  
Working together with the weather icons are the weather tendency  
indicators (located on the left and right sides of the weather icons). When  
the indicator points upwards, it means that the air-pressure is increasing  
and the weather is expected to improve. When the indicator points  
downwards, the air-pressure is dropping and the weather is expected to  
become worse.  
Air pressure over the last 24 hours  
The bar chart indicates the air pressure history trend over the last 24  
hours in 7 steps, 0h, -3h, -6h, -9h, -12h, -18h, and -24h. The “0h”  
represents the current full hour air pressure recording. The columns  
represent the “hPa” (0, ±2, ±4, ±6) at specific time. The “0” in the middle  
of this scale is equal to the current pressure and each change (±2, ±4, ±6)  
represents how high or low in “hPa“ the past pressure was compared to  
the current pressure.  
Taking this into account, one can see how the weather has changed and  
is expected to change. For example, if the indicator is pointing  
downwards together with cloud and sun icons, then the last noticeable  
change in the weather was when it was sunny (the sun icon only).  
Therefore, the next change in the weather will be cloud with rain icons  
since the indicator is pointing downwards.  
33  
34  
If the bars are rising it means that the weather is getting better due to the  
increase of air pressure. If the bars go down, it means the air pressure  
has dropped and the weather is expected to get worse from the present  
time “0h“.

with the recorded time and date.  
Note:  
- Twice to show the MIN outdoor temperature and humidity data  
with the recorded time and date.  
For accurate barometric pressure trends, the Weather Station should  
operate at the same altitude. For example, it should not be moved from  
the ground to the second floor of the house. Should the unit be moved to  
a new location, discard readings for the next 48-60 hours.  
- Three times to return to the current displayed values.  
Once the MIN or MAX data is displayed, press and hold the SET  
key for 3 seconds to reset the respective MIN or MAX record to

If the outdoor temperature and humidity data are not being received  
within three minutes after setting up (or outdoor display always show “-  
-. -” in the outdoor section of the Weather station during normal  
operation), please check the following points:  
To reset the minimum and maximum temperature and humidity  
data, and the times at which they were recorded, press the SET  
key continuously for about 3 seconds. This will reset the MIN/MAX  
data recorded to the current time, date, temperature and humidity.  
The current time taken is the normal displayed time and does not  
regard the time zone set for the unit.

separately.  
LOW BATTERY INDICATOR  
Low battery indicator is displayed on the LCD when the batteries in the  
weather station require changing.  
Using other electrical products such as headphones or speakers  
operating on the 915MHz-signal frequency may prevent correct  
signal transmission or reception. Neighbors using electrical devices  
operating on the 915MHz-signal frequency can also cause  
interference.  
ABOUT THE OUTDOOR TRANSMITTER  
The range of the Thermo-hygro transmitter may be affected by the  
temperature. At cold temperatures, the transmitting distance may be  
decreased. Please keep this in mind when positioning the transmitters.  
Battery power may be reduced for the Thermo-hygro transmitter at cold  
temperatures.  
Note: When the 915MHz signal is received correctly, do not re-open the  
battery cover of either the transmitter or Weather station, as the batteries  
may spring free from the contacts and force a false reset. Should this  
37  
38  
happen accidentally, reset all units (see “Setting up” above), or  
FOLDOUT TABLE STANDS:  
transmission problems may occur.  
The foldout table stands legs are located on the  
backside. Simply unfold the stands on the back. Once  
the foldout table stands are extended, place the weather  
station in an appropriate location.  
The transmission range is around 300 feet from the Thermo-hygro  
transmitter to the Weather station (in open space). However, this  
depends on the surrounding environment and interference levels. If no  
reception is possible despite the observation of these factors, all system  
units have to be reset (see “Setting up” above).  
POSITIONING THE WEATHER STATION  
The Weather station provides the option of table standing or  
wall mounting the unit. Before wall mounting, please check  
that the outdoor data can be received from the desired  
locations.  
POSITIONING THE THERMO/HYGRO TRANSMITTER:  
The remote thermo/hygro transmitter can be placed onto  
any flat surface or wall mounted using the bracket which  
doubles as a stand or wall mount base.  
TO WALL MOUNT:  
1. Fix a screw (not supplied) into the desired wall, leaving  
the head extended out by about 0.2” (5mm).  
2. Place the weather station onto the screw, using the  
hanging hole on the backside. Gently pull the weather  
station down to lock the screw into place.  
TO WALL MOUNT:  
1. Secure the bracket onto a desired  
wall using the screws and plastic anchors.

Do not submerge the units in water. Furthermore, fix all parts in  
place where the units are adequately protected against moisture  
and rain.  
Immediately remove all low powered batteries to avoid leakage and  
damage. Replace only with new batteries of the recommended  
type.  
Do not make any repair attempts to the unit. Return them to their  
original point of purchase for repair by a qualified engineer.  
Opening and tampering with the unit may invalidate their  
guarantee.  
Do not expose the units to extreme and sudden temperature  
changes, this may lead to rapid changes in forecasts and readings  
and thereby reduce their accuracy.  
2. Clip the remote temperature transmitter onto the  
bracket.  
Note:  
The mounting surface can affect the transmission range. If, for instance,  
the unit is attached to a piece of metal, it may then either reduce or  
increase the transmitting range. For this reason, we recommend not to  
place the unit on any metal surfaces or in any position where a large  
metal or highly polished surface is in the immediate vicinity (garage  
doors, double glazing, etc.). Before securing in place, please ensure that  
the Temperature Station can receive the 915MHz signal from the  
temperature transmitter at the positions that you wish to place them.  
CARE AND MAINTENANCE:  
SPECIFICATIONS:  
Extreme temperatures, vibrations and shocks should be avoided as  
these may cause damage to the unit and give inaccurate forecasts  
and readings.  
Temperature measuring range:  
When cleaning the display and casings, use a soft damp cloth only.  
Do not use solvents or scouring agents as they may mark the LCD  
and casings.
