wireless devices, or other phones.
– facing away from radio frequency  transmitters, such as external antennas 
of mobile phone cell stations. (Avoid 
putting the base unit on a bay window or 
near a window.)
L Coverage and voice quality depends on the 
local environmental conditions.
L If the reception for a base unit location is not 
satisfactory, move the base unit to another 
location for better reception.

Note when setting up
Note for connections
LThe 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
LUse 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
LIt 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.
– the handset beeps while you are  engaged in a call or operating the 
answering system remotely.
Panasonic Ni-MH battery 
performance (supplied batteries)
*1 When the clarity booster feature is  turned on (page 17): 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.
L The battery level may not be 
displayed correctly after you replace 
the batteries. In this case, place the 
handset on the base unit or charger 
and let it charge for at least 7 hours.
