10 CONVENTIONAL OPERATION
The radio functions in the conventional mode when using conventional communications channels (non-
trunked).
10.1 CONTROLS
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.
10.1.1 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.
POWER ON-OFF
VOLUME 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 31, which is the loudest level.
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 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.
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.
SIDE OPTION
BUTTON 1
Unsquelches the receiver and allows channel monitoring prior to
transmission. Momentarily removes the Channel Guard decoding from the
channel.
SIDE OPTION
BUTTON 2
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.
