Introduction
L Do not touch the plug with wet hands.
L The AC adaptor is used as the main
disconnect device. Ensure that the AC
outlet is installed near the unit and is
easily accessible.
Battery
To reduce the risk of fire or injury to
persons, read and follow these
instructions.
L Use only the battery(ies) specified.
L Do not dispose of the battery(ies) in a
fire. They may explode. Check with local
waste management codes for special
disposal instructions.
L Do not open or mutilate the battery(ies).
Released electrolyte is corrosive and
may cause burns or injury to the eyes or
skin. The electrolyte may be toxic if
swallowed.
L Exercise care when handling the
battery(ies). Do not allow conductive
materials such as rings, bracelets or
keys to touch the battery(ies), otherwise
a short circuit may cause the battery(ies)
and/or the conductive material to
overheat and cause burns.
L Charge the battery(ies) provided with or
identified for use with this product only in
accordance with the instructions and
limitations specified in this manual.
WARNING:
L To prevent the risk of fire or electrical
shock, do not expose this product to rain
or any type of moisture.
L Unplug this unit 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
and contact an authorised service
centre.
Medical
L Consult 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 unit operates in
the frequency range of 2.4 GHz to 2.48
GHz, and the power output level can
range from 0.04 to 0.1 watts.) Do not use
the unit in health care facilities if any
regulations posted in the area instruct
you not to do so. Hospitals or health care
facilities may be using equipment that
could be sensitive to external RF (radio
frequency) energy.
General Warnings
L This equipment will be inoperable when
mains power fails.
L When a failure occurs which results in
the internal parts becoming accessible,
disconnect the power supply cord
immediately and return this unit to an
authorised service centre.
L Disconnect the telecom connection
before disconnecting the power
connection prior to relocating the
equipment, and reconnect the power
first.
L No “111” or other calls can be made from
this device during a mains power failure.
This equipment shall not be set to make
automatic calls to the Telecom “111”
Emergency Service.
L To minimise the possibility of lightning
damage, when you know that a
thunderstorm is coming, we recommend
that you:
– Unplug the telephone line cord from
the phone jack.
– Unplug the power supply cord from
the AC power outlet.
L The earcap on the handset is
magnetised and may retain metallic
objects.
L This equipment has been tested and
found to comply with AS/NZS 3548:
1995 limits for electromagnetic
interference. Any modifications to any
6
part of the system or to any peripherals
may void the EMC compliance of the
system or the peripherals.
Introduction
For best performance
L The unit’s answering system only
responds to Distinctive Alert cadence(s)
DA1 and DA3.
L Not all telephones will respond to
incoming ringing when connected to the
extension socket.
L This equipment may not provide for the
effective hand-over of a call to another
device connected to the same line.
Important notice
L Under power failure conditions, this
telephone may not operate. Please
ensure that a separate telephone, not
dependent on local power, is available
for emergency use.
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
or greater than 40 °C. Damp basements
should also be avoided.
L The maximum calling distance may be
shortened when the unit is used in the
7
Introduction
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.

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 a BT double
adaptor.

Preparation
Battery performance
After your Panasonic battery is fully
charged, you can expect the following
performance:
Operation Operating time
While in use
(talking)
While not in use
(standby)
While using the
Clarity Booster
feature (page 18)
*1 Handset is off the base unit but not in
use.

Up to 11 days
Up to 3 hours
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 4.
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 maximise the
battery life.
1 Press the notch on the cover firmly and
slide it as indicated by the arrow.
