Adjusting the Audio Tone and Clarity Boost
If you aren’t satisfied with the audio quality of your phone, you can adjust the Audio Tone of the earpiece while on a call. Your phone gives you three audio tone options: low, natural, and high; the default setting, Natural Tone, is rec- ommended for hearing aid users. Audio tone adjustments only apply to the earpiece, not the speakerphone. To ad- just the audio tone:
1.With the phone in talk mode, press 
to cycle through the three audio tone options.
2.When the desired option appears on the display, stop.
3.After two seconds, the displayed audio tone is set, and the display returns to normal.
If you encounter interference while using your phone, you can manually improve the sound by setting the Clarity Boost to on. This works only when the phone is in use, so while you are on a call:
1.Press [menu/clear].
2.Move the cursor to CLARITY BOOST, and then press 
. BOOST ON and B appear on the display. Use the same procedure to turn off Clarity Boost. BOOST OFF appears.
