Personalizing Your Telephone
Changing Volume Levels
You can change the following volume levels:
• Ringer (alerting tone)
• Handset
• Headset
• Background music
• External speaker
You must be using the feature to change the volume level. For example, if you want to change
handset volume level, you must be using the handset. However, you can adjust the ringer
(alerting tone) volume level when the telephone is idle.
To change a volume level:
While using the feature, press (Up) to increase the volume or press (Down) to
decrease the volume.
To save the volume level:
Press (Up) and (Down) simultaneously. Handset volume 11 cannot be saved.
Changing the Ring Tone
You can select one of nine different ring tones.
To change the ring tone:
1. With the handset on-hook, dial 398.
2. Do one of the following to listen to (or turn off) ring tones:
• Press 0 or the RINGER OFF menu button to turn the ringer off.

3. Press (Speaker), #, the ACCEPT menu button, or lift and replace the handset to
select the ring tone.
Adjusting the Display Contrast
You can adjust the display Contrast setting.
To adjust the Contrast setting:

NOTE
Turning the external speaker volume down to the lowest levels may prevent you
from hearing the feature “warning tones” that notify you when errors occur (for
example, when you enter an incorrect feature code).
