For best performance
Base unit location/avoiding noise
The base unit and other compatible Panasonic units use radio waves to communicate with each other.
L For maximum coverage and noise-free
communications, place your base unit: – at a convenient, high, and central
location with no obstructions between
the handset and base unit in an indoor
environment. – away from electronic appliances such as
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.)
L Coverage and voice quality depends on the
local environmental conditions.
L If the recep tion for a base unit location is not
satisfactory, move the base unit to another location for better reception.

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 floor­mounted 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.

batteries. For replacement, we recommend using the Panasonic rechargeable batteries noted on page 4, 8.
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

Voice mail service

Voice mail is an automatic answering service offered by your service provider/ telephone company. After you subscribe to this service, your service provider/ telephone company’s voice mail system answers calls for you when you are unavailable to answer the phone or when your line is busy. Messages are recorded by your service provider/ telephone company, not your telephone. When you have new messages, # is displayed on the handset if message indication service is available. Please contact your service provider/telephone company for details of this service.
Important:
L If # still remains on the display even
after you have listened to new messages, turn it off by pressing and holding {#} for 2 seconds.
L To use the voice mail service provided
by your service provider/telephone company rather than the unit’s answering system, turn off the answering system (page 35). For details, see page 40. (KX-TG6421)
