6.4 Store and reset maximum and minimum values

• As soon as the basic station and the outdoor transmitter

are active the maximum and minimum values for indoor
and outdoor will be stored.

• Press and hold the

button and the recorded maximum

or minimum values will be reset to the actual values.

• During a manual transmitter search all maximum and

minimum outdoor values will be also reset to the current
values.

6.5 Backlight

• Press the

button or the

button to activate the back-

light for few seconds.

7. Positioning and fixing of the basic station and the

outdoor transmitter

• With the foldable leg at the back of the basic station, the

basic station can be placed onto any flat surface or wall
mounted at the respective location by the hanging hole
at the back of the basic station. Avoid the vicinity of any
interfering field like computer monitors or TV sets and
solid metal objects.

• With the hanging hole at the back of the outdoor trans-

mitter, the outdoor transmitter can be wall mounted at
the respective location. Choose a shady and dry position
for the outdoor transmitter. (Direct sunshine falsifies the
measurement and continuous humidity strains the elec-
tronic components needlessly).

• Check the transmission of the signal from the outdoor

transmitter to the basic station (transmission range of up to
100 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 basic station.

8. Care and maintenance

• Clean the devices with a soft damp cloth. Do not use sol-

vents or scouring agents.

• Remove the batteries if you do not use the devices for a

long period of time.

• Keep the devices in a dry place.

6. Getting started

6.1 Insert batteries

• Place both instruments on a desk with a distance of

approximately 1.5 meter. Avoid getting close to possible
interference sources (Electronic devices and radio installa-
tions).

• Open the battery compartment of the transmitter by

pressing the notch with your thumb and then lift the
cover.

• Insert two new batteries 1,5 V AAA polarity as illustrated.
• Close the battery compartment again.
• Open the battery compartment of the basic station and

insert two new batteries 1.5 V AAA, polarity as illustrated.

• All LCD segments will be displayed for about a few se-

conds.

• Close the battery compartment again.

6.2 Reception of outdoor temperature

• After the batteries are inserted the outdoor temperature

will be transmitted automatically to the basic station.

• The reception symbol appears on the upper display. The

basic station will scan the outdoor temperature.

• If the reception of the outdoor temperature fails, “- -”

appears on the display. Check the batteries and try it
again. Check if there is any source of interference.

• You can start the initialization manually. Hold the
