For your safety
To prevent severe injury and loss of life/
property, read this section carefully before 
using the product to ensure proper and safe 
operation of your product.
WARNING
Power connection
LUse only the power source marked on the 
product.
LDo not overload power outlets and

may cause electric shock and/or excessive 
heat resulting in a fire.
LRegularly remove any dust, etc. from the 
AC adaptor/power plug by pulling it from the 
power outlet, then wiping with a dry cloth. 
Accumulated dust may cause an insulation 
defect from moisture, etc. resulting in a fire.
LUnplug the product from power outlets if it 
emits smoke, an abnormal smell, or makes 
an unusual noise. These conditions can 
cause fire or electric shock. Confirm that 
smoke has stopped emitting and contact 
the Panasonic Call Center at 1-800-211-
PANA (1-800-211-7262).
LUnplug from power outlets and never touch 
the inside of the product if its casing has 
been broken open.
LNever touch the plug with wet hands. 
Danger of electric shock exists.
Installation
LTo prevent the risk of fire or electrical shock, 
do not expose the product to rain or any 
type of moisture.
LDo not place or use this product near 
automatically controlled devices such as 
automatic doors and fire alarms. Radio 
waves emitted from this product may cause 
such devices to malfunction resulting in an

LDo not spill liquids (detergents, cleansers, 
etc.) onto the telephone line cord plug, or 
allow it to become wet at all. This may 
cause a fire. If the telephone line cord plug 
becomes wet, immediately pull it from the 
telephone wall jack, and do not use.
Medical
LConsult the manufacturer of any personal 
medical devices, such as pacemakers or 
hearing aids, to determine if they are 
adequately shielded from external RF 
(radio frequency) energy. (The product 
operates in the frequency range of 1.92 
GHz to 1.93 GHz, and the RF transmission 
power is 115 mW (max.).)
LDo not use the product in health care 
facilities if any regulations posted in the

electrical storm.
LNever install telephone line jacks in wet 
locations unless the jack is specifically 
designed for wet locations.
LNever touch uninsulated telephone wires or 
terminals unless the telephone line has 
been disconnected at the network interface.
LUse caution when installing or modifying 
telephone lines.
LThe AC adaptor is used as the main 
disconnect device. Ensure that the AC 
outlet is installed near the product and is 
easily accessible.

Released electrolyte from the batteries is 
corrosive and may cause burns or injury to 
the eyes or skin. The electrolyte is toxic and 
may be harmful if swallowed.
LExercise care when handling the batteries. 
Do not allow conductive materials such as 
rings, bracelets, or keys to touch the 
batteries, otherwise a short circuit may 
cause the batteries and/or the conductive 
material to overheat and cause burns.
LCharge the batteries provided with or 
identified for use with this product only, in 
accordance with the instructions and 
limitations specified in this manual.
LOnly use a compatible base unit (or

TVs, radios, personal computers, 
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.)
LCoverage and voice quality depends on the 
local environmental conditions.
LIf 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.)
LThe 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 4). 
Emergency power can be supplied to the 
unit by connecting a Panasonic battery 
back-up power supply noted on page 4.
Note for battery installation
LUse the supplied rechargeable 
batteries. For replacement, we 
recommend using the Panasonic 
rechargeable batteries noted on page 
4, 6.
LWipe the battery ends (S, T) with a 
dry cloth.
LAvoid 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.
LClean 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:
LThe 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 15): 3 hours max.
Note:
LActual battery performance depends 
on a combination of how often the 
handset is in use and how often it is 
not in use (standby).
LEven after the handset is fully 
charged, the handset can be left on 
the base unit or charger without any ill 
effect on the batteries.
LThe 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.
