CODE GUARD OPERATION
Code Guard
TM
(sometimes called tone code) allows one radio
or group of radios to be selectively called within a system. If
the radio has been programmed with Code Guard, use the
following receive and transmit instructions:
CODE GUARD RECEIVE
1. Turn power on by turning the volume
knob clockwise.
2. Select a Code Guard channel by
turning the channel selector knob.
3. Adjust volume (see Receive, step 3, on
the previous page.
4. Set Code Guard mode by pushing the
soft function button (top gray button is
the factory default) that was
preprogrammed to toggle Code Guard
on or off.
If your dealer reassigned the gray soft
function button to a different function,
you can also select Code Guard by
pushing
or
until Monitor Mode
is displayed and then push [E]nter to
toggle tone mode [ ]. Push [H]ome
for normal display.
If your radio is already set to tone
mode, the function menu will show
Tone Mode instead of Monitor Mode.
If you see tone mode in the display,
just press [H]ome for normal display.
You will only hear a message if your radio
receives the proper Code Guard value.
