The radio functions in the conventional mode when using conventional communications channels (non-
trunked).  

The radio features two rotary control knobs and an emergency button mounted on the top of the radio. 
Push-To-Talk and option buttons are mounted on the side. The front mounted keypad has six buttons on 
the P5350 Scan model and 15 buttons on the P5370 System model. 

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.

 

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 voice group selection knob, loosen the set screw on the voice group 
selection knob metal base (using a 1.27mm hex wrench), and remove the 
voice group selection knob metal base. Replace the 16 channel ring with the 
channel stop ring located at the desired channel. Re-install the voice group 
selection knob metal base, tighten the set screw, and re-install the voice 
group selection knob. 

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. 

Push-To-Talk must be pressed before voice transmission begins.  

Unsquelches the receiver and allows channel monitoring prior to 
transmission. Momentarily removes the Channel Guard decoding from the 
channel. 

Activates one of a number of programmable software options selected 
during PC programming. Programmable options include hi/low power 
settings, keypad lock, LCD contrast, and LCD and keypad back lighting.
