RING VOLUME

You can select one of these three ring volumes for the phone:

RINGING LOW — the ring is quiet.

RINGING HIGH — the ring is loud.

SILENT SERVICE — the phone does not ring. Instead, the keypad and display back- lights flash, CALL flashes on the display, and the phone sounds a short beep when a call is received. This setting also turns off the phone’s keytones (even if the keytones feature is set to ON).

Follow these steps to set the ring volume.

1.Press MENU 9WXYZ . The phone displays the cur- rent setting (RINGING HIGH, RINGING LOW, or SILENT SERVICE).

2.Repeatedly press or to scroll through the settings.

3.When you hear or see the setting you want to use, press OK to store that setting.

Note: If you select SILENT SERVICE, the phone displays SILENT when there is no call in progress and when you are not using another function.
