Troubleshooting

If other phones in your home or office are having the same problem, the problem is in your wiring or local service. Contact your telephone service provider (charges may apply).

I cannot hear a ring tone from the headset when there is an incoming call.

The headset does not have an external ringer. You can only hear the ring tone when you are wearing the earpiece.

If you have pressed MUTE/FLASH on the headset when it is ringing, it mutes the ring tone of the headset. The ring tone resumes on the next call.

You may have too many extension phones on your telephone line to allow all of them to ring simultaneously. Try unplugging some of the other phones.

The layout of your home or office might be limiting the operating range. Try moving the telephone base to another location, preferably to a higher location.

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.

Install the battery again, and then place the cordless headset in the headset charger. Wait for the cordless headset to reestablish its connection with the telephone base. Allow up to one minute for this to take place.

Your telephone line cord may be defective. Install a new telephone line cord.

If other phones in your home or office are having the same problem, the problem is in your wiring or local service. Contact your telephone service provider (charges may apply).
