Wireless thermometer
• Press and hold the -/MIN button while the alarm
event is displayed to clear the recording.
9. Trend arrows
• The trend arrows indicate whether the values for
temperature of the last 15 minutes are increasing or
decreasing.
• If the values remain the same, there is no display.
10. Installation
• When placed outdoors, choose a shady and dry
place for the transmitters. Direct sunlight may trig-
ger incorrect measurement and continuous humidi-
ty damages the electronic components needlessly.
• The waterproof cable sensor is ideal for the temper-
ature control of the refrigerator, freezer, aquarium,
terrarium, pool or pond.
• Before the final installation, make sure that the
measured values are transmitted from the transmit-
ter at the desired installation site to the base station.
• Make sure to avoid the vicinity of any source of
interference such as computer screens, TV sets or
solid metal objects. Within solid walls, especially
ones with metal parts, the transmission range (max.
100 m) can be reduced considerably.
• To wall-mount the transmitter, screw the holder to
the wall and click the transmitter into the holder.
11. Battery replacement
• As soon as the corresponding battery symbol
appears in the display, please change the batteries
of the base station or transmitters.
• Please note: When the batteries are changed, the
contact between the transmitters and the base sta-
tion must be restored – so always restart all devices
or start a manual transmitter search.
