About cordless telephones

• Privacy: The same features that make a cordless telephone convenient create some limitations�

Telephone calls are transmitted between the telephone base and the cordless handset by radio

waves, so there is a possibility that the cordless telephone conversations could be intercepted by

radio receiving equipment within range of the cordless handset� For this reason, you should not

think of cordless telephone conversations as being as private as those on corded telephones�

• Electrical power: The telephone base of this cordless telephone must be connected to a working

electrical outlet� The electrical outlet should not be controlled by a wall switch� Calls cannot

be made from the cordless handset if the telephone base is unplugged, switched off or if the

electrical power is interrupted�

• Potential TV interference: Some cordless telephones operate at frequencies that may cause

interference to televisions and VCRs� To minimize or prevent such interference, do not place

the telephone base of the cordless telephone near or on top of a TV or VCR� If interference is

experienced, moving the cordless telephone farther away from the TV or VCR often reduces or

eliminates the interference�

• Rechargeable batteries: Exercise care in handling batteries in order not to create a short circuit

with conducting 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�

• Nickel-metal hydride rechargeable batteries: Dispose of these batteries in a safe manner� Do not

burn or puncture the battery� Like other batteries of this type, if burned or punctured, they could

release caustic material which could cause injury�

When the battery in this unit has reached the end of its useful life, please dispose of it according

to your local environmental laws and regulations� For information about recycling cell phone

batteries, go to: http://www�rbrc�org�
