after 60 seconds, remove the batteries from both units and wait for  
at least 60 seconds before reinserting them.  
6.  
Insert the batteries in the third transmitter as soon as the "channel  
2" icon and outdoor data are displayed on the Weather Station.  
Then within 2 minutes, the channel 3 outdoor data from the third  
transmitter will be displayed and the channel icon will shift back to  
"1" once the third transmitter is successfully received. If this does  
not happen after 2 minutes, remove the batteries from both units,  
and then restart the process from step 1.  
4.  
5.  
The outdoor temperature and humidity data from the first  
transmitter (channel 1) and the signal reception icon  
should be  
displayed on the Weather Station. If this does not happen after 2  
minutes, remove the batteries from both units, and then restart the  
process from step 1.  
Note: You must insert the batteries into the third transmitter within  
45 seconds after the Weather Station displays the information of  
the first transmitter - or immediately after reception of the second  
transmitter is finished.  
The distance between the Weather Station and the transmitter  
should not be more than 330 feet to ensure sufficient 915 MHz  
transmission. (See notes on “Positioning” and “915 MHz  
Reception”).  
Insert the batteries in the second transmitter as soon as the signal  
reception icon  
and outdoor data are displayed on the Weather  
Station. Then within 2 minutes, the channel 2 outdoor data from the  
second transmitter and the "channel 2" icon should be displayed on  
the Weather Station. If this does not happen after 2 minutes,  
remove the batteries from both units, and then restart the process  
from step 1.  
7.  
Note : You must insert the batteries into the second transmitter  
within 45 seconds after the Weather Station displays the  
information of the first transmitter.  
IMPORTANT:  
Transmission problems will arise if the setup for additional sensors is not  
followed as described above. Should transmission problems occur, it is  
9
10  
necessary to remove the batteries from all units and start again the set-up  
from step 1.  
3.  
Replace the battery cover.  
Note:  
Note:  
When changing batteries in any of the units, all units  
need to be reset by following the setup procedures.  
This is due to a random security code assigned by the  
transmitter at start-up. This code must be received  
and stored by the Weather Station in the first 3  
minutes of power being supplied to the transmitter.  
If the signal reception is not successful on the first frequency of  
915MHz for 45 seconds, the frequency is changed to 920MHz and  
the learning is tried for another 45 seconds. If it is still not  
successful the reception is tried for 45 seconds on 910MHz. This  
will also be done during re-synchronization.  
When the weather station is receiving the WWVB time signal, the  
outdoor transmitter data signal will temporarily not be received by  
the weather station. During this short period of time, the outdoor  
readings shown on the weather station will not be renewed until the  
WWVB time signal is successfully received.  
TO INSTALL AND REPLACE BATTERIES IN THE WEATHER

BATTERY CHANGE:  
It is recommended to replace the batteries in all units on an annual basis  
to ensure optimum accuracy of these units.  
ABOUT WWVB RADIO CONTROLLED TIME  
Please participate in the preservation of the  
environment. Return used batteries to an authorized  
depot.  
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  
13  
14  
limited during daylight hours. The wireless weather station will search for  
a signal every night when reception is best.  
FUNCTION KEYS:  
Weather Station  
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  
The Weather Station has 5 function keys:  
(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  
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.

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: After setup, 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.  
FORECAST  
FORECAST  
FORECAST  
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).  
Sunny  
Cloudy with sunny intervals  
Rainy  
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.  
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.  
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  
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.  
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.  
Note:  
Once the weather tendency indicator has registered a change in air  
pressure, it will remain permanently displayed on the LCD.  
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  
37  
38  
has dropped and the weather is expected to get worse from the present  
time “0h“.  
TOGGLING AND RESETTING THE OUTDOOR DATA

To toggle between the current outdoor and the MAX/MIN outdoor  
temperature and humidity data and the times (for temperature data  
only) they were recorded press the OUT/+ key:  
Note: 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.

least 5 to 6.5 feet (1.5 to 2 meters) away from any interfering  
sources such as computer monitors or TV sets.  
2.  
3.  
Avoid placing the transmitters onto or in the immediate proximity of  
metal window frames.  
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.  
41  
42  
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  
happen accidentally, reset all units (see “Setting up” above), or  
transmission problems may occur.  
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.  
TO WALL MOUNT:  
The transmission range is around 330 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).  
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.  
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.  
FOLDOUT TABLE STANDS:  
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.

CARE AND MAINTENANCE:  
Extreme temperatures, vibrations and shocks should be avoided as  
these may cause damage to the unit and give inaccurate forecasts  
and readings.  
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.  
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.  
TO WALL MOUNT:  
1.  
Secure the bracket onto a desired wall using  
the screws and plastic anchors.  
Clip the remote temperature transmitter onto  
the bracket.  
2.  
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  
decrease 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.
