Problems In The Temperature Sensor Module - AREX TL-300 Mode D'emploi

1.2. Problems in the temperature sensor module

The receiver receives signals from sensors, but fails to registrate
signals from one sensor in particular.
Potential problems:
- Batteries are missing or are at a low charging level
- Reversed polarity of the sensor's batteries
- The sensor's location is outside of the receiver's reception
range
- Damage to the sensor (by corroded battery contacts, moisture
or battery leakage)
E
- Problems in the radio signal communication
N
Suggested solutions:
G
- Insert fully charged batteries in the sensor and repeat the
L
communication test (please check the polarisation of the
batteries before inserting!!)
I
- Check the battery contacts and remove all corrosion and
moisture effects.
