Adjusting the Ringer, Earpiece and Speaker Volume

Adjusting the Ringer Volume

You can choose from four ringer volume settings (off, low, medium, and high)

separately on each handset or the base.

With the phone in standby, press or on the handset or VOLUME or

VOLUME on the base. The handset or base sounds the ringer at that level.

Use on the handset or VOLUME on the base to make the ringer volume

louder. Use on the handset or VOLUME on the base to make it softer or

turn it completely off.

When you hear the ringer volume level you want to use, stop pressing keys.

The handset or base will use the new ringer volume starting with the next incoming call.

Note: If you set the ringer volume to Off, the handset or base won't ring. Other handsets or base will ring according
to their individual settings.

You may download a copy of the manual here. To adjust the ringer volume, see the instructions on page 37. To adjust the voice volume during a call, press up/down-arrow.

I believe the problem is even with the ringer off, if you are on one line the other line will ring which is annoying if you are on the phone. I have yet to figure out how to prevent that but would be glad to post an answer when and if I find one.

Make sure the ringer is on (page 8).

The handset may be too far from the telephone base. Move it closer to the telephone base.
There may be too many extension phones on the telephone line to allow all of them to ring simultaneously. Try unplugging some of them.
If the other telephones in your home are having the same problem, the problem is in the wiring or local service. Contact the local telephone company (charges may apply).
Other electronic products can cause interference to your cordless telephone. Try installing your telephone as far away as possible from the following electronic devices: wireless routers, radios, radio towers, pager towers, cellular telephones, digital telephones, intercoms, room monitors, televisions, VCRs, personal computers, kitchen appliances, and other cordless telephones.
Test a working telephone at the telephone wall jack. If another telephone has the same problem, the problem is in the telephone wall jack. Contact your local telephone company (charges may apply).
The telephone line cord might be malfunctioning. Try installing a new telephone line cord.
Wait for the handset to synchronize with the telephone base. Allow up to one minute for this to take place.
