8.1.1  Buttons and Knobs 
This section describes the primary function of the button and knob controls. Other functions associated 
with these controls are detailed in later sections. 
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 31, which is the loudest level.

VOLUME KNOB 
CONTROL KNOB 
Selects systems or group/channels (depending on programming). 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 channel knob, loosen the set screw on the channel knob metal base 
(using a 1.27mm hex wrench), and remove the channel knob metal base. 
Replace the 16 channel ring with the channel stop ring located at the desired 
channel. Reinstall the channel knob metal base, tighten the set screw, and 
reinstall the channel knob. 
EMERGENCY/ 
HOME BUTTON 
Automatically selects the pre-programmed Group/System by pressing and 
holding for a programmed duration. It can also be used to declare an 
emergency by pressing and holding for a programmed duration. The button 
must be pre-programmed for either operation, but not both. 
PTT BUTTON 
Push-To-Talk must be pressed before voice transmission begins. In trunked 
mode the radio’s ID is transmitted upon depression of the PTT button.

associated with it) and returns the radio to the selected talk group. 
Terminates individual and telephone interconnect calls. 
In conventional mode: Unsquelches the receiver and allows channel 
monitoring prior to transmission. Momentarily removes the Channel Guard 
decoding from the channel.
