Contact Tracfone customer service on this, but my guess is the phone is defective.

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

The headset volume is turned to zero. Hit the "menu" key on the headset and it should take you to "ringer setting", hit select for the ringer volume and turn the volume up. Not very intuitive but that should get you going!

To turn off the ringer on my Vtech cordless phones, I have had to turn off the base ringer & all handsets.

Base Ringer:
Press Menu and listen carefully, continue to press menu until you hear "Base Ringer, to change base ringer press change", hit change and it will say "Off", then you must hit the PLAY/STOP button to save your change.
Handset:
Press the program button and use your "up/down" key to cycle until you see the Ringer selection. Press SELECT and then use your "up/down" key(s) to cycle until the OFF selection is see on the handset screen. Press select.

To turn your ringer back on, you do the following. For your handset, you push Menu, scroll to ringer settings, then push select, Press select again for ringer volume, then scroll up to turn on and increase the ringer volume. Then press Save once its at the desired volume. To change your base ringer, while it is not in use, push the ringer up button until you hear the desired setting. That should fix your problems.
