indicates main unit batteries are low.
NOTE Do not use rechargeable batteries. We
recommend that you use alkaline batteries with this
product for longer usage and lithium batteries in
temperatures below freezing.
The sensor collects temperature and humidity readings
approx. every 40 seconds and sends them to the
main unit. The main unit can collect data from up to
3 sensors.
To set up the sensor:
1. Remove the screws from the battery door.
2. Insert the batteries, matching the polarity (+ / -).

EN
The transmission range may vary depending on many
factors. You may need to experiment with various
locations to get the best results.
Standard Alkaline batteries contain signicant amounts
of water. Because of this they will freeze in low
temperatures of approximately -12°C (10°F). Disposable
Lithium batteries have a much lower threshold for
temperature with an estimated freezing range of below
-30°C (-22°F).
Wireless ranges can be impacted by a variety of factors
such as extremely cold temperatures. Extreme cold
may temporarily reduce the effective range between the
sensor and the base station. If the unit's performance
fails due to low temperature, the unit will resume proper
functioning as the temperature rises to within the normal
temperature range (i.e. no permanent damage will occur
to the unit due to low temperatures).
3. Select a channel. Make sure you use a different
channel for each sensor.
4. Place the sensor near the main unit. Press RESET
on the sensor.
5. Simultaneously press CHANNEL and MEM on the
main unit to initiate signal sending between the sensor
and main unit.
6. Close the battery door and secure the screws.
7. Place the sensor in the desired location using the table
stand or wall mount. SENSOR DATA TRANSMISSION

CLOCK RECEPTION
RECEPTION SIGNAL
To enable and force a signal search:
Press and hold for 2 seconds.
To disable the signal reception:
Press and hold for 2 seconds.
STRONG SIGNAL WEAK SIGNAL NO SIGNAL
SET CLOCK
If the clock signal reception is enabled and a signal is
being received the clock does not need to be manually
set.
1. Press and hold MODE for 2 seconds.
2. Press or to change the settings.
3. Press MODE to conrm.
4. The settings order is: time zone offset, hour, minute,
year, month, day and language.
NOTE The time zone offset can be used to set the clock
up to + / - 9 hours from the received clock signal time.
If you have disabled the clock signal reception (i.e.
manually setting the clock), do not set a value for time
zone offset.
NOTE The language options are English (E), German
(D), French (F), Italian (I), and Spanish (S).
Press MODE to choose between the clock with seconds
and clock with weekday display modes.
Clock signal reception indicator:
To search for a sensor:
Simultaneously, press and hold MEM and CHANNEL
for 2 seconds.
NOTE If the sensor is still not found, check the batteries,
obstructions, and remote unit location.
This product is designed to synchronize its date and
time automatically once it is within range of:
• DCF-77 generated from Frankfurt, Germany for
Central Europe.
• MSF-60 generated from Rugby, England.
The clock collects the radio signals whenever it is within
1500 km (932 miles) of a signal.
NOTE Slide the EU / UK switch to appropriate position for
your location. Repeat each time you reset the unit.
NOTE Initial reception takes 2-10 minutes for rst set
up or when RESET is pressed. Once complete, the
reception icon will stop blinking. If the signal is weak, it
can take up to 24 hours to get a valid signal.

and activate it again after 24 hours.
To ensure barometric readings are reliable set the altitude
to reect distance from sea level at your position.
1. Press and hold PRESSURE for 2 seconds.
2. Use and to set the altitude in 10 m (33 ft)
increments from -100 m (-328 ft) to 2500 m (8202
ft).
3. Press PRESSURE to conrm.
Barometer readings from the past 24 hours are stored by
the main unit and used to provide weather forecast.
To select barometer measurement unit:
Press PRESSURE to toggle between mb and inHg.

ICE WARNING
If the channel 1 sensor falls between 3°C to –2°C (37°F
to 28°F), ashes to warn you that the temperature is
approaching freezing.
NOTE The warning will automatically stop if the
temperature goes outside the ice-warning range.
