9.10 Setting The Volume Control
The volume control on your telephone is a multipurpose control you can
use to set the volume of the ringer, speaker, handset, headset, background
music, and the group listening mode. You can press the VOLUME UP or
VOLUME DOWN button once for each change in loudness you desire.
You can adjust the loudness of the distant party at any time during a call
whether you are listening over the speaker, the headset, the handset, or
the group listen mode by pressing the VOLUME UP or VOLUME
DOWN button. When the call ends, the system resets the loudness to the
default setting.
You can change the default setting for any volume control setting by
pressing ✳✳ 7 when the loudness is at the desired level. The volume
level remains at this setting until you select a new default.
NOTE: Impact SCS 8324S-**, 8324F-**, and 8312S-** telephones
support the optional ICVOL-** handset. The ICVOL-** is an
amplified handset with its own volume control, making it
useful in noisy environments. For ordering information,
contact your Comdial dealer.
