10. Positioning and fixing of the base station and the trans-
mitter
• With the foldable leg at the back of the unit, the base station
can be placed onto any flat surface. Avoid the vicinity of any
interfering field like computer monitors or TV sets and solid
metal objects.
• With the foldable leg at the back of the transmitter it can be
placed onto any flat surface or wall mounted at the respec-
tive location by the hanging hole at the back of the unit.
Choose a shady and dry position for the transmitter. (Direct
sunshine falsifies the measurement and continuous humidi-
ty strains the electronic components needlessly).
• Check the transmission of the signal from the outdoor trans-
mitter to the base station (transmission range 50 m free
field). Within ferro-concrete rooms (basements, superstruc-
tures), the received signal is naturally weakened.
• If necessary choose another position for the outdoor trans-
mitter and/or base station.
11. Care and maintenance
• Clean your instrument with a soft damp cloth. Do not use
solvents or scouring agents.
• Remove the batteries if you do not use the product for a
lengthy period.
• Keep the instrument in a dry place.
11.1 Battery replacement
• When the battery symbol appears on the display of the out-
door temperature, replace the batteries in the transmitter.
• When the battery symbol appears on the display of the
indoor temperature, replace the batteries in the base station.
• Please note:
When the batteries are changed, the contact between trans-
mitter and base station must be restored – so always insert
new batteries into both units or start a manual transmitter
search.
