I cannot
register the
headset.
For registration to a cordless telephone:
• You must be using a compatible AT&T
DECT 6.0 cordless telephone. Visit
www.telephones.att.com for a list of
compatible telephones.
• Your cordless telephone has a maximum
number of handsets that may be registered
to the telephone base. In terms of
registration, the telephone base treats a
headset like a handset. Check the Adding
and registering handsets section of the
telephone user’s manual for the maximum
number of handsets allowed. If the
maximum number of handsets are already
registered, you will need to follow the deregistration instructions in the telephone
user’s manual then re-register the handsets
and/or headsets you wish to use.
For registration to a headset base:
• You can register a maximum of two
headsets and one dial pad to the headset
base. If you already have two headset(s)
and one dial pad registered to the headset
base, then you must de-register all the
headset(s) and dial pad before you register
a different headset.
• If you registered the expansion headset
to a headset base, see the user’s
manual for your headset base model

Especially about cordless headsets
• Privacy: The same features that make a cordless headset convenient create some limitations. Telephone calls are transmitted between the headset base and the headset by radio waves,
so there is a possibility that your cordless headset conversations could be intercepted by radio receiving equipment within
range of the cordless headset. For this reason, you should
not think of cordless headset conversations as being as
private as those on corded telephones.
• Electrical power: The headset base of this cordless headset
must be connected to a working electrical outlet which is not
controlled by a wall switch. Calls cannot be made from the
headset if the headset base is unplugged or switched off, or
if the electrical power is interrupted.
• Potential TV interference: Some cordless headsets operate at
frequencies that may cause interference to TVs and VCRs. To
minimize or prevent such interference, do not place the headset base of the cordless headset near or on top of a TV or VCR.
If interference is experienced, moving the cordless headset
farther away from the TV or VCR will often reduce or eliminate
the interference.
40

charger.
• Lithium-ion rechargeable batteries: Dispose of these batteries
in a safe manner. Do not burn or puncture. Like other batteries
of this type, if burned or punctured, they could release caustic
material which could cause injury.
The RBRC™ Seal means that the manufacturer is voluntarily
participating in an industry program to collect and recycle lithiumion rechargeable batteries when taken out of service within the
United States. These batteries may be taken to a participating local
retailer of replacement batteries or recycling center. Or you may
call 1-800-8-BATTERY for locations accepting spent Li-ion batteries.
