9. Positioning of display unit and transmitter
• Choose a shady and dry position for the transmitter. (Direct sun-
shine falsifies the measurement and continuous humidity strains
the electronic components needlessly).
• 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 100 m free field, within ferro-
concrete rooms, especially with metal parts, the received signal
is naturally weakened).
• If necessary choose another position for transmitter and/or dis-
play unit.
• Use the bracket stand for mounting or standing when the signal
is received successfully.
10. Care and maintenance
• Clean the instruments with a soft damp cloth. Do not use sol-
vents or scouring agents.
• Remove the batteries if you do not use the products for a
long period of time.
• Keep the instruments in a dry place.

10.1 Battery replacement

• When the batteries are used up, the low battery indicator
appears on the display (RX=base station, TX = transmitter).
• Please note: When the batteries are changed, the contact
between transmitter and receiver must be restored – so
always insert new batteries into both units or start a manual
transmitter search.
