5.1 Additional transmitters
• The sensor will automatically transmit temperature to the display unit on
channel 1 after batteries are inserted.
• For having more than one external transmitter, select a different channel (1 to
3) for every transmitter by pressing the “CH” button on the transmitter while
the channel number is flashing. Press and hold the “CH” button on the display
unit for 2 sec. to start initialization manually. flashes on the LCD of the dis-
play unit and the new transmitter will be received automatically (*channel 4
and 5 are reserved for other models).
• The temperature measured by the sensor is shown on the display of the display
unit. If you have installed more than one transmitter, press “CHANNEL” button
(on the display unit) to change between the outdoor transmitters.
• You can also choose an alternating channel display. Press CHANNEL button.
After the last registered channel a circle symbol appears for alternating
channel.
6. 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 need-
lessly).
• Place the display unit at the final position. Avoid the vicinity of any interfering
field like computer monitors or TV sets and solid metal objects.
• Check the transmission of the signal from the transmitter to the display unit
(transmission range 75 m free field, within ferro-concrete rooms, especially with
metal parts, the received signal is naturally weakened.
• If necessary chose another position for transmitter and/or display unit.
• Use the bracket stand for mounting or standing when the signal is received
successfully.
7. Battery replacement
• When the batteries of the main unit are used up, the low battery icon appears
on the top left of the display. When the batteries of the transmitter are used
up, the low battery icon appears next to the outdoor temperature display.
• Use alkaline batteries only. Observe correct polarity. Low batteries should be
changed soon to avoid the damage resulting from a leaking battery. Batteries
contain harmful acids. Wear protective glasses and gloves when handling with
leaked batteries.
• Attention: Please do not dispose of old electronic devices and used batteries in
household waste. To protect the environment, take them to your retail store
or to nearest civic amenity site to be disposed of according to national or local
regulations.
8. Instructions
• Always read the users manual carefully before operating the unit.
• Use a pin to press the “RESET” button if the unit does not work properly.
• Avoid placing the instrument near interference sources/metal frames such as
computer or TV sets.
• Do not expose the instrument to extreme temperatures, vibration or shock.

4.3 Thermometer
4.3.1 Change °C/°F
• Press “UNIT” button to change between °C or °F as temperature unit.
4.3.2 Maximum/Minimum function
• Press “MEMORY” button to show the maximum (“MAX”) values of indoor and
outdoor temperature. Press “MEMORY” button again to show minimum
values (“MIN”).
• Hold “MEMORY” button for 2 seconds while the maximum or minimum values
are displayed to clear the recorded maximum and minimum readings.
4.4. Weather forecast symbols
• There are 4 different coloured weather symbols (sunny, slightly cloudy, cloudy,
rainy). In case of storm warning the rain symbol is flashing.
• The animated rolling display will pause 19 sec. in the place of the current fore-
cast symbol. The current forecast symbol is permanently shown on the top of
the LCD.
• The weather forecast symbols indicate an improvement or worsening of the
future weather conditions based on the current weather, which doesn’t have
to correspond exactly with the weather indicated on the symbol.
4.5 Animation and backlight
• Slide the “BACKLIGHT AUTO/OFF/ON” switch on the backside to choose the
following options:
1. Position “AUTO“: Backlight and animation for 16 sec. (with power adapter
24 sec.), via IR motion sensor (wave hand 5 cm in front of the sensor) or
automatically in the selected illumination cycle (see 4.5.1.).
2. Position “ON“: Backlight and animation in continuous operation (only with
power adapter), with battery operation like position “AUTO”
3. Position “OFF”: Disable the backlight and animation function.
4.5.1 Illumination cycle (for position AUTO)
• Hold „UNIT“ button for 2 seconds to enter illumination cycle setting mode.
• Press “▲” or “▼“ button to select the following options: 5, 10, 20, 30 or 60
minutes. A longer illumination cycle will save more battery power.
4.5.2 Animation on/off
• Confirm the setting of the illumination cycle by pressing “UNIT” button. Press
“▲” or “▼“ button to switch animation “ON” or “OFF”. Confirm with “UNIT”
button.
5. Outdoor thermo sensor
• Press “°C/°F” button on the transmitter to change the temperature unit on the
sensor display from °C to °F.
• Use a pin to press the “RESET” button on the remote sensor to transmit tempe-
rature to the display unit manually (e.g. for testing or in case of loss of trans-
mitter signal).
• After successful installation close the cover of the battery compartment and
replace the protection cover by pushing outwards the two latches in the
bottom.
