POWER ON-OFF VOLUME KNOB

VOICE GROUP SELECTION CONTROL KNOB

Applies power to and adjusts the receiver’s volume. Rotating the control clockwise applies power to the radio. A single alert tone (if enabled through programming) indicates 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 programmed level of zero (displayed as OFF in the display) up to 40, which is the loudest level.

Selects pre-programmed channels. This is a 16-position rotary knob.

Note: A mechanical stop, which can limit the positions accessed, is shipped with the radio but must be installed. To install the mechanical stop, remove the Voice Group Selection control knob, loosen the set screw on the Voice Group Selection control knob metal base (using a 1.27mm hex wrench), and remove the Voice Group Selection control knob metal base. Replace the 16 channel ring with the channel stop ring located at the desired channel. Re- install the Voice Group Selection control knob metal base, tighten the set screw, and re-install the Voice Group Selection control knob.
