5.1 Transmission problems
“ ” appears on the display or no reception symbol
• Check the transmission of the signal from the transmitter to the
display unit (transmission range 30 m free field). Within ferro-con-
crete rooms (basements, superstructures), especially with metal
parts, the received signal is naturally weakened.
• If necessary choose another position for transmitter and/or display
unit.
6. Battery replacement
• When the battery symbol appears on the upper display change
the batteries of the display unit.
• When the battery symbol appears on the lower display change the
batteries of the transmitter.
• 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.
Caution:
Please do not dispose of old electronic devices and empty batter-
ies in household waste. To protect the environment, take them to
your retail store or to appropriate collection sites according to
national or local regulations.

heit) as temperature unit.
5. 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.
