4 Maintenance
4.1 Battery
The radio module is equipped with a 3.6 V
lithium-thionyl chloride (Li-SOCl2) battery
that is not rechargeable but can be replaced.
Its useful life varies between 12 (

WAN
169 fixed, three transmissions per day of
the measurements plus one weekly trans-
mission on the status of the module) with
the factory set up in the following operating
conditions:
– between -10°C and +0°C for 10% of
lifespan
– between 0°C and +30°C for 80% of lifespan
– between +31 °C and +55 °C for 10% of
lifespan
l
WARNING!
Humidity and intense heat may
damage the battery and reduce
its lifespan.
The radio module calculates the residual
lifespan of the battery on the basis of stored
parameters, such as estimated consump-
tion of the electronic board in stand-by
mode, transmitter consumption and num-
ber of transmissions performed.
Battery life depends largely on the frequen-
cy of data transmission set.
4.2 Cleaning
No particular cleaning procedures are
required. However, the installation area
should be kept clean and periodic checks
should be performed to ensure the re-
quired environmental conditions are met.
d
PROHIBITED
Use of abrasive products, petrol
or trichloroethylene is not per-
mitted.
