• After successful installation screw up the battery compart-
ment of transmitter carefully.
• For having additional external transmitters (maximum3),
proceed as described in chapter 3. Select for each sensor a
different channel by the CHANNEL button before inser-
ting batteries.
4.7 Positioning of display unit and transmitter
• Choose a shady and dry position for the transmitter.
(Direct sunshine falsifies the measurement and continuous
humidity strains the electronic components needlessly)
• Place the Display Unit at the final position. Avoid the vici-
nity of any interfering field like computer monitors or TV
sets and solid metal objects.
• Check the transmission of 433 MHz signal from the trans-
mitter to the Display Unit (transmission range 60 m free
field). Within ferro-concrete rooms (basements, super-
structures), the received signal is naturally weakened.
• If necessary chose another position for transmitter and/or
display unit.
• Fix the transmitter by using plastic hanger.
5. Battery Replacement
• When the batteries are used up, low battery icon appears
at the indoor or outdoor temperature row.
• Use alkaline batteries 1.5 V AA only. Observe correct pola-
rity.
Attention:
Please do not dispose of old electronic devices and empty
batteries in household waste. To protect the environment,
take them to your retail store or to appropriate collection
sites according to national or local regulations.
6. Notes
• Always read the users manual carefully before operating
the unit.
• Avoid placing the clock near interference sources/metal
frames such as computer or TV sets.
• Do not expose the instrument to extreme temperatures,
vibration or shock.
