BASIC OPERATION
TURNING THE RADIO ON
Typically, mobile radio installations require the 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 setting of the vehicle ignition.
Verify with the installer how the radio has been connected.
From the OFF position, rotate the ON/OFF Volume
knob clockwise until the knob clicks. The radio
performs a diagnostic test and then sounds three short
tones to indicate the radio has passed the diagnostic test
and is ready for operation. The display comes ON and
indicates the currently selected channel.
SELECTING OR CHANGING CHANNELS
Rotate the Channel Selector Knob clockwise or
counterclockwise until the desired channel appears in

counterclockwise to decrement to the previous channel.
