The Weather station
Note: This weather station receives only one outdoor transmitter.
First, insert the batteries into the Temperature transmitter. (see “Install
and replace batteries in the Temperature transmitter“).
Immediately after and within 30 seconds, insert the batteries into
Weather station (see “Install and replace batteries in the Weather
station”). Once the batteries are in place, all segments of the LCD will
light up briefly. Following the time as 12:00 and the weather icon will be
displayed. If these are not displayed after 60 seconds, remove the
batteries and wait for at least 10 seconds before reinserting them.
After inserting the batteries, the Weather station will start receiving data
from the transmitter. The outdoor temperature and the signal reception
icon should then be displayed on the Weather station. If this does not
happen after 3 minutes, the batteries will need to be removed from both
units and reset from step 1.
In order to ensure sufficient 915 MHz transmission however, this should
under good conditions be a distance no more than 100 meters (330
feet) between the final position of the Weather Station and the
transmitter (see notes on “Mounting” and “915 MHz Reception”).
HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE
The Weather Station uses 3 x AA, IEC LR6, 1.5V batteries. When batteries
will need to be replaced, the
low battery icon will appear on
the LCD. To install and replace
the batteries, please follow the
Lift up the battery
Insert batteries observing
the correct polarity (see
HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE

1.5V battery. To install and replace the batteries,
please follow the steps below:
Remove the battery compartment cover at the
back of the transmitter.
Insert the batteries, observing the correct polarity
Replace the battery compartment cover on the
In the event of changing batteries in any of the units, all units need to be reset
by following the setting up procedures. This is because a security code is
assigned by the transmitter at start-up and this code must be received and
stored by the Weather station in the first 3 minutes of power being supplied to
It is recommended to replace the batteries in all units regularly to ensure
optimum accuracy of these units (Battery life See Specifications below).

WEATHER FORECAST AND TENDENCY
THE WEATHER FORECASTING ICONS :
There are 3 weather icons in the second section of LCD which can be
displayed in any of the following combinations :
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. However, 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.
The icons display weather forecasts 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
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
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 stagnant most of the time (for example
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), remove the batteries and re-insert them after about
30 seconds. 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. Again, disregard weather forecasts for the next 4860 hours as this will allow time for operation at a constant altitude.
THE WEATHER TENDENCY INDICATOR
Working together with the weather icons are the weather tendency indicators
(located on the left and right hand side of the weather icons). When the
indicator points upwards, it means that the air-pressure is increasing and the
weather is expected to improve, but when indicator points downwards, the
air-pressure is dropping and the weather is expected to become worse.
Taking this into account, you will see how the weather has changed and how
it 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 (sun icon only). Therefore, the next change
in the weather will be the cloud with rain icons since the indicator is pointing
Once the weather tendency indicator has registered a change in the air
pressure, it will remain permanently visualized on the LCD.
INDOOR TEMPERATURE AND MIN/MAX RECORDS
The indoor temperature and indoor MIN/MAX records are displayed on the
last section of the LCD.
Note: The MIN/MAX indoor temperature range is 15ºF to 99ºF with 1ºF
resolution (-9ºC to + 38ºC with 1°C resolution).
OUTDOOR TEMPERATURE AND MIN/MAX RECORDS
The outdoor temperature and outdoor MIN/MAX records are displayed on the
last section of the LCD.
In normal display mode, press and hold the MIN/MAX RESET key for 3
seconds. This will reset the indoor and outdoor MIN/MAX temperatures.
LOW BATTERY INDICATOR
Low battery indicator is displayed on the LCD when the batteries require
915 MHz RECEPTION CHECK
The Weather station should receive the temperature data within 3 minutes
after set-up. If the temperature data is not received 3 minutes after setting up
(not successfully continuously, the outdoor display shows “- - -” ), please
check the following points:
The distance of the Weather station or transmitter should be at least 1.5
to 2 meters (5 to 6.5 feet) away from any interfering sources such as
computer monitors or TV sets.
Avoid positioning the Weather station onto or in the immediate proximity
of metal window frames.
Using other electrical products such as headphones or speakers
operating on the same signal frequency (915MHz) may prevent correct
signal transmission and reception.
Neighbors using electrical devices operating on the 915MHz signal
frequency can also cause interference.
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 then reset all units (see Setting up above) otherwise
transmission problems may occur. The transmission range is about 100 m
from the transmitter to the Weather station (in open space). However, this
depends on the surrounding environment and interference levels. If no
Note: The MIN/MAX outdoor temperature resolution range is -40ºF to 140ºF
with 1ºF resolution (-40ºC to + 60ºC with 1°C resolution).
RESETTING THE INDOOR AND OUTDDOR MIN/MAX RECORDS
Note: All the MIN/MAX records will be reset at the same time.
reception is possible despite the observation of these factors, all system units
have to be reset (see Setting up).
