For best performance
Base unit location/noise
The base unit and handset use radio
waves to communicate with each other.
For maximum distance and noise-free
operation, we recommend the following:
L Placing the unit away from electrical
appliances such as a TV, personal
computer or another cordless phone.
L Placing the base unit in a HIGH and
CENTRAL location with no obstructions
such as walls.
L Raising the antenna vertically.
L If you use the handset near a microwave
oven which is being used, noise may be
heard. Move away from the microwave
oven and closer to the base unit.
L If you use the handset near another
cordless phone’s base unit, noise may
be heard. Move away from the other
cordless phone’s base unit and closer to
your base unit.
Environment
L Keep the unit away from electrical noise
generating devices, such as fluorescent
lamps and motors.
L The unit should be kept free from
excessive smoke, dust, high
temperature and vibration.
L The unit should not be exposed to direct
sunlight.
L Do not place heavy objects on top of the
unit.
L When you leave the unit unused for a
long period of time, unplug this unit from
power outlet.
L The unit should be kept away from heat
sources such as heaters, kitchen stoves,
etc. It should not be placed in rooms
where the temperature is less than 5 °C
(41 °F) or greater than 40 °C (104 °F).
Damp basements should also be
avoided.
L The maximum calling distance may be
shortened when the unit is used in the
following places: Near obstacles such as
hills, tunnels, undergrounds, near metal
objects such as wire fences, etc.
L Operating near 2.4 GHz electrical
appliances may cause interference.
Move away from the electrical
appliances.

For assistance, please call 1-800-211-PANA (7262). 9
Connections
Note:
L Use only the included Panasonic AC adaptor PQLV19.
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.
L The unit will not work during a power failure. We recommend connecting a standard
telephone to the same telephone line or to the same telephone jack using the Panasonic
KX-J66 T-adaptor. Emergency power can be supplied to the unit by connecting a
Panasonic battery back-up power supply noted on page 5.

indicator will light, and “Charging” will
be displayed.
L “Charge completed” is displayed
when the battery has been fully charged.
The CHARGE indicator will remain lit.

Battery performance
After your Panasonic battery is fully
charged, you can expect the following
performance:
*1 Handset is off the base unit but not in
use.
Note:
L Battery power is consumed whenever
the handset is off the base unit, even
when the handset is not in use. The
longer you leave the handset off the
base unit, the shorter you can actually
talk on the handset. Actual battery
performance depends on a combination
of how often the handset is in use and
how often it is not in use.
L Once the battery is fully charged, you do
not have to charge it again until
“Recharge battery” is displayed or
7 flashes. This will maximize the
battery life.
Battery replacement
If battery performance diminishes, make
sure you have cleaned the charge
contacts and fully charged the battery. The
battery needs to be replaced if any of the
following are displayed after a few phone
calls even when you have fully charged the
battery.
–“Recharge battery”
– 7 (flashing)
–“Charge for 6h”
– 8
L Use only the rechargeable Panasonic
battery noted on page 5.
1 Press the notch on the cover firmly and
slide it as indicated by the arrow.
