Especially about cordless headsets

Privacy: The same features that make a cordless headset con- venient create some limitations. Telephone calls are transmit- ted between the headset base and the headset by radio waves, so there is a possibility that your cordless headset conversa- tions 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 head- set 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.
