Controls; Power On-Off Volume Knob; System/Group Channel Knob - Ericsson EDACS ORION Operator's Manual

This section describes the buttons, keys and rotary knobs used to control the
Orion Scan and System Model radios. All functions and controls of the Scan
radio operate the same as the corresponding functions and controls on the
System radio. The Scan radio is equipped with a 4-button keypad and the
System radio is equipped with a 16-button keypad.
Many of the control buttons and keys have or can be programmed to have a
primary function and a secondary function. The SCAN button can be pro-
grammed (as a secondary function) to toggle the keypad keys between their
primary function and their secondary function.

POWER ON-OFF VOLUME KNOB

Rotating the control clockwise increases the volume level. Minimum volume
levels may be programmed into the radio to prevent missed calls due to al-
low volume setting. While adjusting the volume, the display will momentar-
ily indicate the volume level (i.e. VOL = 31). The volume range is from a
minimum level of zero (displayed as "OFF" in the display) up to 31 which is
the loudest level.
