CONTROLS
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
programmed (as a secondary function) to toggle the keypad keys between
their primary function and their secondary function.
POWER ON-OFF VOLUME KNOB
This rotary Knob applies power to the radio and adjusts the
receiver volume. Rotating the control clockwise out of
detente applies power to the radio. A single alert tone
sounds (if enabled through programming) to indicate the
radio is operational.
Rotating the control clockwise increases the volume level. Minimum volume
levels may be programmed into the radio to prevent missed calls due to a low
volume setting. While adjusting the volume, the display will momentarily
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.

stop. See
