Maintenance and Troubleshooting

Important safety information

Replace batteries only as described in your user’s manual.

•

Do not burn or puncture batteries — they contain caustic
chemicals.

This power adapter is intended to be correctly oriented in a

•
vertical or floor mount position. The prongs are not designed

Especially about cordless headsets

Privacy: The same features that make a cordless headset con-

•

venient 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.
