Instructions for the use of NiMH batteries:
After you have inserted the NiMH batteries, we recom-
mend that the mobile unit be fully charged and then dis-
charged until the battery low beep is heard, i.e. without
replacing the batteries in the charging shell. This ensures
that the charge status displayý7 of the mobile unit is
adapted to the increased operating life of the NiMH bat-
teries.
You can subsequently place your mobile unit in the charg-
ing shell each time it is used. Charging is electronically
controlled which ensures that the batteries are charged
optimally.
