All the controls for the P
ANTHER
300M mobile radio are located on the front of
the control unit and described below:
ON/OFF Volume Knob
This knob powers the radio ON/OFF and controls the volume level of the
received audio at the speaker. When the knob is in the OFF position, rotate
the knob clockwise until the knob clicks to turn the power to the radio ON. To
turn the power to the radio OFF, rotate the knob counterclockwise until it
clicks and stops. Rotate the knob clockwise to increase the volume of
receive audio. Rotate the knob counterclockwise to decrease the volume of
receive audio.
Typically, mobile radio installations require a vehicle ignition switch to be in
the Accessory or Run position before the radio will power ON. In some
applications, the radio is wired directly to the battery and the radio will power
ON regardless of the vehicle ignition switch setting.
Channel Knob
This six position rotary knob selects the desired channel from a programmed
list of channels. Rotate the Channel Knob clockwise or counterclockwise
until the raised rib aligns with the desired channel number. The displayed
channel number is consistent with the Channel Knob position.
