Troubleshooting
I am getting a buzzing sound on my headset or corded base
speakerphone.
• Your telephone may experience interference from the headset.
To overcome this problem, move the headset base at least 12
inches away from the telephone.
• Other electronic products such as HAM radios and other DECT
phones can cause interference with your cordless headset.
Try installing your headset as far away as possible from these
types of electronic devices.

headset may take a second or two to find the headset or
telephone base and produce a dial tone. This is normal. Wait
an extra second before dialing.
• Eliminate any background noise. Noise from a television, radio
or other appliances may cause the headset to not dial out
properly. If you cannot eliminate background noise, try dialing
from another room with less background noise.
• If the other phones in your home are having the same
problem, the problem is in your wiring or local service. Contact
your telephone service provider (charges may apply).
The other party cannot hear my voice during a call.
• If you registered the accessory cordless headset to a headset
base, try adjusting the speaking volume setting on the headset
base. See the volume section of the user’s manual for your

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.
36
Appendix
Important safety information
• 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.
• Rechargeable batteries: This product contains nickel-
cadmium, nickel-metal hydride or lithium-ion rechargeable
batteries. Exercise care in handling batteries in order not to
create a short circuit with conductive material such as rings,
bracelets, and keys. The battery or conductor may overheat
and cause harm. Observe proper polarity between the battery
and the battery 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
lithium-ion 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.
