Cause/solution
L When you are using fully-charged Ni-MH batteries
(supplied batteries);
In continuous use: 15 hours max.
Not in use (standby): 250 hours (10 days) max.
L It is normal for batteries not to reach full capacity
at the initial charge. Maximum battery
performance is reached after a few complete
cycles of charge/discharge (use).
L Actual battery performance depends on a
combination of how often the handset is in use
and how often it is not in use (standby).
L Even after the handset is fully charged, the
handset can be left on the base unit or charger
without any ill effect on the batteries.
L If the batteries are fully charged until & is
displayed, but ) is displayed after a few calls,
replace the batteries with new ones.
L The PIN is a 4-digit number that must be entered
in order to change certain base unit settings. The
default PIN is "0000".
L You must subscribe to a Caller ID service. Contact
your service provider/telephone company for
details.
L The message "You must first subscribe
to Caller ID." will be displayed until you
receive caller information after subscribing to a
Caller ID service.
L You are using the handset or base unit in an area
with high electrical interference. Re-position the
base unit and use the handset away from sources
of interference.
L Move closer to the base unit.
L If you use a DSL/ADSL service, we recommend
connecting a DSL/ADSL filter between the base
unit and the telephone line jack. Contact your
DSL/ADSL provider for details.
L Clean the battery ends (S, T) and the charge
contacts with a dry cloth and charge again.
