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.

Muting the Ringer (One call only)
While the phone is ringing, press /Mute or END on the handset or on the base to mute the ringer

These can be the only things that are causing your problems:

Ringer mute
You can mute the ringer temporarily when the telephone is ringing.
Press OFF/CLEAR or MUTE to temporarily silence the ringer. The next call will ring normally.

Ringer volume
You can change the handset ringer volume to a comfortable level. The ringer can also be turned off so the telephone does not ring when there are incoming calls.
To adjust the ringer volume:
Press MENU/SELECT to display the menu when the handset is not in use.
Press or to select >RINGER VOLUME, then press MENU/SELECT.
Press or to adjust the volume. A sample of each volume level will be played as you adjust it.
Press MENU/SELECT to save your selection. You will hear a confirmation tone.


Make sure the ringer is on (page 8).
Make sure the telephone line cord and power adapter are plugged in properly (page 2).
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.

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

To increase the volume for the ringer, the volume buttons located on the charging stand can adjust the volume. To change the ringer volume on the phone instead of using the stand, go to the menu on the phone and type 1 then 1 again. This will take you to the ringer volume screen. You can select between the options:{1}: Low {2}: Medium {3}: {0}: Off.

While you're in the middle of a call use the same button to adjust the ringer volume. It should only adjust the in call volume.

If the ringout volume is very low, then try not to select a soft, silent or low ringing tone. Try to choose a ringing tone that is loud so that you can hear your phone ringout.
Hope that was helpful?

Without the exact model it is difficult to find the manual.

Here the manual for 900 series/996:Uniden EZI996.

I also quote from manual:

Selecting the Ringer Tone and Volume

Base ringer on/off
The ringer switch allows you to set the base ringer on or
off. If you set the switch to off, you never hear the base
ringer tone.

Base ringer tone
Press the ringer tone button in standby mode to select one of 7 ringer tones.

Base ringer volume
Slide the ringer volume adjuster to set the base ringer volume.

Handset ringer tone and volume
Press the volume up key or volume down key (labeled as the volume/ /+ or volume/ /- key) in standby mode to select one of five ringer tones and volume combinations

Try adjusting the ringer volume, dial tone volume, and speaker volume. Make sure that the ringer type selection is not set to off. Also make sure that you are not bridging your call.

You can also use the Upgrade feature built into the phone to look for updates which may resolve your issue.

If this has only started happening recently, Restore the default settings and see if it resolves your issue.
