pressed.
• Press and hold the MEM/- button, when the maximum or minimum values are dis-
played to set the maximum and minimum values to the current values.
• When replacing batteries the maximum and minimum values are deleted automat-
ically.
7.2 Frost alarm
• On the display appears the symbol for frost, when the outdoor transmitter shows
an outdoor temperature between -2°C...3°C (28°F...37°F).
• The symbol for frost will be flashing in the display for the outdoor values.
• Once the outdoor temperature rises above the mentioned measuring range, the
symbol for frost will disappear.
7.3 Setting of the temperature unit
• Press the °C/°F switch to change between °C (Celsius) or °F (Fahrenheit) as tem-
perature unit.
8. Outdoor transmitter
• After inserting the batteries into the outdoor transmitter the transmitter will auto-
matically transmit the outdoor values to the base station on channel 1.
• Press the RESET button you can restart the outdoor transmitter manually (e.g. for
testing or in case of loss of transmitter signal).
• After successful installation close the battery compartment of the outdoor trans-
mitter carefully.
• The channel number appears on the display.
• The outdoor temperature and humidity appear in the display in sequence.
8.1 Additional outdoor transmitters
• For having more than one outdoor transmitter select with the CH1/2/3 switch in
the battery compartment of the transmitter for each single outdoor transmitter a
different channel (CH1, CH2 or CH3). Insert two new batteries 1,5 V AA as indicat-

• The outdoor values and the channel number will be shown on the display of the
base station. If you have installed more than one outdoor transmitter, press the
CH/+ button on the base station to change between the channels 1 to 3.
• You can also choose an alternating channel display.
• Press and hold the CH/+ button to activate the alternating channel automatically.
• Press the CH/+ button again briefly, to deactivate the alternating channel and the
desired outdoor transmitter will be shown permanently.
9. Positioning and fixing of base station and the outdoor transmitter
• Choose a shady and dry position for the outdoor transmitter. (Direct sunshine fal-
sifies the measurement and continuous humidity strains the electronic compo-
nents needlessly).
• Place the base station 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 outdoor transmitter to the base sta-
tion (transmission range of up to 50 m free field). Within ferro-concrete rooms
(basements, superstructures), the received signal is naturally weakened.
• If necessary choose another position for the outdoor transmitter and/or base sta-
tion.
• Is the transmission successfully, you can wall mount the outdoor transmitter or
place it onto a flat surface.
10. Care and maintenance
• Clean the devices with a soft damp cloth. Do not use solvents or scouring agents.
• Remove the batteries from both instruments if you do not use the products for a
long period of time.
• Keep the devices in a dry place.
10.1 Battery replacement
• Change the batteries of the outdoor transmitter when the battery symbol appears
on the display of the outdoor values of the base station or on the display of the
outdoor transmitter.
• Change the batteries when the functions of the base station become weak.
• Please note: When the batteries are changed, the contact between outdoor trans-
mitter and base station must be restored – so always insert new batteries into
both devices or start a manual transmitter search.
