  • The speakerphone battery may be defective. Contact our customer service for assistance.

I cannot dial out.

  • You must use a telephone on the same line to dial out. Once you have dialed the number, you can press on the speakerphone to take the call.
  • If other telephones in your home are having the same problem, the problem is in your wiring or telephone service. Contact your telephone service provider (charges may apply).

The red or blue light keeps flashing on the speakerphone.

  • Different flashing patterns of the red and/or blue lights indicate different conditions of the speakerphone. See “Speakerphone layout” on page 4.

Maintenance

Taking care of your speakerphone

Your wireless speakerphone contains sophisticated electronic parts, so it must be treated with care.

Avoid rough treatment

Save the original packing materials to protect your speakerphone if you ever need to ship it.

Avoid water

Your speakerphone can be damaged if it gets wet. Do not use the speakerphone outdoors in the rain, or handle it with wet hands. Do not install the speakerphone charger near a sink, bathtub or shower.

Electrical storms

Electrical storms can sometimes cause power surges harmful to electronic equipment. For your own safety, take caution when using electrical appliances during storms.

Cleaning your speakerphone

Your speakerphone has a durable plastic casing that should retain its luster for many years. Clean it only with a soft cloth slightly dampened with water or mild soap. Do not use excess water or cleaning solvents of any kind.

About the cordless speakerphone

  • Privacy: The same features that make a cordless speakerphone convenient create some limitations. Telephone calls are transmitted between the telephone base and the cordless speakerphone 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 speakerphone. For this reason, you should not think of cordless telephone conversations as being as private as those on corded telephones.
  • Electrical power: The speakerphone must be connected to a working electrical outlet. The electrical outlet should not be controlled by a wall switch.
  • Potential TV interference: Some cordless speakerphones operate at frequencies that may cause interference to televisions and VCRs. To minimize or prevent such interference, do not place the telephone base of which the cordless speakerphone is registered near or on top of a TV or VCR. If interference is experienced, moving the cordless speakerphone farther away from the TV or VCR often reduces or eliminates the interference.
  • 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.

The RBRC® Seal

The RBRC® Seal means that the manufacturer is voluntarily participating in an industry program to collect and recycle nickel-metal hydride 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 Ni-MH batteries.
RBRC® and 1 (800) 8 BATTERY® are registered trademarks of the Rechargeable Battery Recycling Corporation
