your face and speak at a normal voice level. the microphone
is quite sensitive so it is not necessary to raise your voice or
shout. release the PTT when you have finished talking. the
icon will disappear.
IMPORTANT: Always listen to ensure the channel is free
before transmitting.
TIME-OUT TIMER
the radio has a built-in time-out timer that automatically
limits transmissions to a maximum of 3 minutes of continuous
operation. this feature is required by the AcmA to prevent
accidental blocking of the frequency should your Ptt switch
become jammed or be otherwise pressed accidentally. the
time-out period can be changed by your dealer.
When the time-out timer activates, the radio will beep for 5
seconds then the
symbol will flash continuously. normal
operation will be restored once the Ptt is released.
BaCKLIGHTING
the liquid crystal Display and keys are back lit for easy
viewing at night. the backlight remains on while the radio is

there are three back-light settings available;
BKLGT (Brightness Setting): Provides a continuously

BaNDWIDTH FILTER SETTINGS
to accommodate the blending of the newer narrowband uHF
cB 80 channel plan with the original 40 channel wideband
system, your radio is fitted with two user-selectable receiver
bandwidth filters. While either of these will provide superb
receive audio, selecting the wide filter will further increase
the tolerance of the receiver to 40 channel wideband radios
that might otherwise sound over-modulated or slightly off
frequency on channels 1 – 40. selecting the narrow receive
filter will increase the selectivity of the radio to strong
interfering signals from adjacent channels.
to select the desired filter, press and hold the MENU key
to enter the menu, then press the MENU key repeatedly
until NBFLT (narrowband Filter) or WBFLT (Wideband
Filter) is displayed. rotate the Channel knob (or press
or ) to make the desired selection.
When finished, briefly press the PTT to exit from the
menu.
