Speakerphone, Handset, and Headset Volume
While the phone is in use, during the desired mode, press the Vol (+ or -) buttons until you
reach a comfortable listening level. The phone stores the setting after the last button press.

eight different tones, or turn the ringer OFF.
NOTE: If you select OFF, the cursor automatically moves to the CID ON/OFF option. Use the Vol
(+ or -) buttons to scroll up or down to select CID ON or OFF. (ON allows the unit to detect
