Troubleshooting

•Move the cordless headset closer to the telephone base. You might have moved out of range.

•Reset the headset. Power off the headset and then power it on.

•Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless headset. Try installing your telephone base as far away as possible from these types of electronic devices.

I get noise, static, or a weak signal even when I’m near the telephone base.

•If you subscribe to high-speed Internet service (DSL - digital subscriber line) through your telephone line, you must install a DSL filter between the telephone line cord and the telephone wall jack. The filter prevents noise and caller ID problems caused by DSL interference. Contact your DSL service provider for more information about DSL filters.

•You may be able to improve the performance of your cordless headset by installing the telephone base at least one foot from any cordless telephone system. If separating them by one foot does not help, try moving the headset farther away.

•Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless headset. Try installing your telephone base as far away as possible from these types of electronic devices.

•Do not install this headset near a microwave oven or in the same electrical outlet. You may experience decreased performance while the microwave oven is operating.

•If your headset is located near a modem, move your headset and modem further apart from each other.

•Relocate your telephone base to a higher location. You may experience better reception by elevating the telephone base.
