Note:
L Battery operating time may be
shortened over time depending on
usage conditions and surrounding
temperature.
L Battery power is consumed whenever
the handset is off the base unit or
charger, even when the handset is not in
use. Hence the longer you leave the
handset off the base unit or charger, the
less time you may actually talk using the
handset.
