	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.

	knob metal base (using a 1.27mm hex wrench), and remove the
	Voice Group Selection control knob metal base. Replace the 16

	base, tighten the set screw, and re-install the Voice Group
	Selection control knob.
