Troubleshooting

My calls cut in and out while I’m using my deskset.

Other electronic products such as HAM radios and other DECT phones can cause interference with your deskset. Try installing your phone as far away as possible from these types of electronic devices.

Do not install the deskset near a microwave oven or on the same electrical outlet. You might experience decreased performance while the microwave oven is operating.

If you plug the main telephone base in with a modem or surge protector, plug it (or modem/surge protector) into a different location. If this does not solve the problem, relocate the main telephone base or modem farther apart from one another, or use a different surge protector.

Relocate the main telephone base to a higher location. The main telephone base might have better reception when installed in a high area.

If other telephones in your building are having the same problem, contact your telephone service provider.

Excessive background noise will cause a speakerphone to fade in and out. Try controlling the background noise by turning off any audio devices near the speakerphone. Also, try to avoid interrupting the person at the other end of the conversation while they are speaking. If background noise cannot be controlled, you should stop speakerphone operation and return to normal handset mode.

When using a deskset speakerphone, controlling background noise in your environment is essential. While you are listening to your party, press MUTE to temporarily turn your microphone off. When it is your turn to speak, remember to press MUTE again to turn the microphone on.

My caller ID isn’t working.

Caller ID is a subscription service. You must subscribe to this service from your telephone service provider for this feature to work on your phone.

The caller must be calling from an area that supports caller ID.

Both your and your caller’s telephone service providers must use caller ID compatible equipment.

If you subscribe to high-speed Internet service (DSL - digital subscriber line) through your telephone lines, you must install a DSL filter between each telephone line cord and telephone wall jack. The filter prevents noise and caller ID problems resulting from DSL interference. Please contact your DSL service provider for more information about DSL filters.
