Radio Settings
As soon as radio operation mode is activated, the meter sends an
encrypted radio telegram according to OMS (Open Metering Standard):
Telegram in C1 mode:
Current value + last 15 monthly values.
Standard radio settings:
A radio signal is sent starting on the first day of the month, for 5
working days, Monday to Friday from 6:00 a m to 8:00 p m in
intervals of one minute
If other radio settings and/or other radio telegrams are requested,
changes can be made by means of a communication head (KoKo)
and configuration software (see paragraph "Additional Functions").
