Features
Volume, Brightness, and Contrast Controls
Description
A keyset user can press Volume Up and Volume Down to interactively adjust the volume of the following
features while they are active:
❥ Intercom handset calls
❥ Intercom Handsfree calls
❥ Outside handset calls
❥ Outside Handsfree calls
❥ Paging receive volume
❥ Background Music
❥ Ringing
❥ Off-Hook Ringing
There are nine steps in the Volume Control adjustment range. This makes it easier for the keyset user to set
up just the right volume levels. The settings a user makes are retained after a system reset or power-down.
Volume Control Presets
The volume control presets allow the keyset user to preset the default volume for Ringing, Off-Hook Ring-
ing, and incoming Page announcements while their telephone is idle. Presets for the remaining volume con-
trols are not required since the user can easily adjust those volumes while idle. For example, to adjust the
volume of Background Music, just press
HOLD to active BGM and then adjust the volume.
Display Brightness and Contrast Control
While a keyset is idle, pressing Volume Up or Volume Down adjusts the contrast of the display. There are
eight user-selectable contrast control values. The value a user sets is “remembered” by the system and auto-
matically restored in the event of a power down or system reset.
The brightness and contrast control presets let the keyset user preset the default active brightness, idle
brightness, and contrast for their keyset display. The brightness presets are not available to a 24-button key-
set since it doesn’t offer a backlit display.
