Especially about cordless headsets

Privacy: The same features that make a cordless headset convenient create some limitations. Telephone calls are transmitted between the telephone 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 telephone 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 telephone base is unplugged or switched off, or if the electrical power is interrupted.
