Note when setting up
Note for connections
L The AC adaptor must remain
connected at all times. (It is normal for
the adaptor to feel warm during use.)
L The AC adaptor should be connected
to a vertically oriented or floor-
mounted AC outlet. Do not connect
the AC adaptor to a ceiling-mounted
AC outlet, as the weight of the adaptor
may cause it to become disconnected.
During a power failure
The unit will not work during a power
failure. We recommend connecting a
corded-type telephone (without AC
adaptor) to the same telephone line or to
the same telephone line jack using a
Panasonic T-adaptor (page 5).
Emergency power can be supplied to the
unit by connecting a Panasonic battery
back-up power supply noted on page 5.
Note for battery installation
L Use the supplied rechargeable
batteries. For replacement, we
recommend using the Panasonic
rechargeable batteries noted on page
5, 7.
L Wipe the battery ends (S, T) with a
dry cloth.
L Avoid touching the battery ends (S,
T) or the unit contacts.
Note for battery charge
L It is normal for the handset to feel
warm during charging.
L Clean the charge contacts of the
handset, base unit, and charger with a
soft and dry cloth once a month. Clean
more often if the unit is exposed to
grease, dust, or high humidity.
Battery level
Note:
L The batteries need to be charged if:
– the handset alerts you with a voice
announcement (talking battery
alert) after you finish talking or
listening to a message.
(KX-TG6421 series: page 3)
– the handset beeps while you are
engaged in a call.
– the handset beeps while you are
operating the answering system
remotely. (KX-TG6421 series: page
3)
Panasonic Ni-MH battery
performance (supplied batteries)
*1 When the clarity booster feature is
turned on (page 16): 3 hours max.
Note:
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.
