8.8.8
Power consumption
Note
The power consumption on batteries depends
on the connected load, signal levels and type of
signal (alarm tone, duty cycle, speech). It is
recommended to measure the actual current
drawn from the batteries in power save mode,
idle mode and alarm tone mode to check the
calculated battery capacity. When calculating
the battery capacity, also take into account that
the capacity decreases during the lifetime of the
battery. Also see section 33.3.
