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.
L After the handset is fully charged,
displaying "Charge completed", it
may be left on the base unit (or charger)
without any ill effect on the battery.
L The battery level may not be displayed
correctly after you replace the battery. In
this case, place the handset on the base
unit (or charger) and let charge for 7
hours.
