The two-byte value of the error flag is shown in the table below. Please note that the first and the second byte represent the very same error, in
the so called "IS" and "WAS" flavour, with "IS" meaning that the alarm/error is currently present, while "WAS" meaning it was present at some time
in the past.

5. Maintenance
5.1 Battery
The radio module is equipped with a 3.0 V lithium manganese battery that is not rechargeable but can be replaced. The typical lifespan of the
battery is 11 years, calculated using factory set-up (mode T1, short frame: one message every two minutes)
• 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
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 consumption
of the electronic board in stand-by mode, transmitter consumption and number of transmissions performed. Battery life depends largely on the
frequency of data transmission set.
Danger
If the battery is empty, it is necessary to contact the metering operator for the correct replacement procedure. The battery must be
disposed of in compliance with applicable laws on waste disposal in the country of installation.
Cause
Electrical or electronic devices interfere with the
signal
Battery empty
Mechanical fraud alarm active
Fixing screw stripped
Faulty module
Mechanical fraud alarm active
Solution
Move devices to a sufficient distance away
Move the receiver closer
Replace the battery (contact the metering operator)
Contact the metering operator
Contact the metering operator
Contact the metering operator
