Safety
• The indoor unit should never be
exposed to rain and moisture.
• Never expose the outdoor sensor to
temperatures beyond the specified levels,
to prolonged sunlight or to rain.
• Never use old and new batteries, or alkaline
and rechargeable batteries together.
• Remove batteries if the device will not be used
for a long period of time. Old batteries can begin
to leak and damage the device.
• Always remember to place the batteries in the
direction of the arrows. The wrong polarity (+/-)
can damage the device.
• Damage due to tampering is not covered
by the guarantee.
• Do not modify the device in any way.

Display viewing angle
Sensor
Remove battery by pushing it downward in direction
of arrow and insert 2 x AAA/LR03 batteries. Ensure
batteries are inserted with correct polarity (+/-) as
marked in battery compartment.
Replacing batteries
If the batteries are exposed to very low or very high
temperatures for a prolonged period of time they can
become less effective, which will reduce the range
between sensor and receiver.
• When the display luminance has weakened it is
time to replace the batteries in the receiver.
• If the symbol for a weak battery appears in the dis-
play it is time to change the batteries in the sensor.
Synchronisation of weather station
and sensor
The accompanying outdoor sensor is preset to
the weather station’s channel 1 (CH 1). Press + /
CHANNEL one or more times on the weather station
to select channel 1 (CH1).
As soon as you insert the batteries, the synchronisa-
tion of sensor and receiver starts automatically. The
units should therefore be placed near to one another
to ensure that synchronisation succeeds (If the out-
door temperature appears on the display synchro-
nisation has succeeded). Once synchronised, the
sensor and receiver can be placed in their intended
locations within functional range.
1. Synchronising an additional sensor: Press
+ / CHANNEL one or more times on the weather
station to select channel 2 (CH2).
2. Hold in +/CHANNEL until starts to flash;
the weather station will now start to search
for a sensor on channel 2.
3. Remove the battery cover of the second sensor,
set the selector to position 2 and then insert
two batteries according to the polarity markings.
Replace the battery cover.
4. The temperature and humidity readings from
sensor 2 will now be shown at the same time
as the CH2 symbol. If no readings are shown
on channel 2, you must reset and repeat the
synchronisation procedure: Press RESET on the
front of sensor 2 once.
5. Repeat the above procedure for sensor 3 if required.
The weather station
display is designed to
be best viewed at a
60-degree angle as in the
Figure. Hence the display
may appear dim when
viewed from straight on.
Getting started
Insert batteries
Weather station (receiver)
Remove the battery cover by pushing it outwards in
direction of the arrow and insert 3 AA/LR6-batteries.
Make sure you insert the batteries with correct
polarity (+/-) as marked in the battery compartment.
