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

click menu 3 times. click either repeat/rew or skip/ff to set to either 2 for 2 rings or 4 for 4 rings or 6 for 6 rings or h5 for toll saver THEN press set/ringer to save your change. Answering machine will answer after 4 rings if you wanted the 4 & saved by pressing set/ringer. Thats all there is to it.

Pick up the handset.
Use the volume up and down key to pick the ringer volume level.
Your ring will come back

usually this is done one of two ways
if the phone has a menu button
press it once then use the arrow keys until you see "ring" or "ring tone" in the display
then use the arrow keys again and you should hear different ring tones. when you find the one you like press the menu button to lock it in

if the phone has a program button and no menu button
keep pressing the program button until you see "ring tone" in the display.then use the arrow keys until you hear the ring tone you like. then press the program button several times until you exit the programming mode.

you can follow the above steps to set the ringer volume also

Follow the instructions on page 36 of the manual.
