INITIAL SET-UP AND SELF-TEST
CM Initial Set-Up and Self-Test. If the CM does not operate correctly, perform the
troubleshooting procedures on page 5-13. If you still cannot operate, set RT FCTN
to SQ ON, and set the other controls as needed (this bypasses the CM so you may
continue to operate).

Test CM:
(1) Set CM FCTN to TEST.
(2) Adjust DIM and check displays.
All displays must light.
l At the end of the test, CHAN
and VAR must show ‘Gd”, and
CONTROL must be at M or S
(see example shown).
l To stop test, set CM FCTN
to a different position.
l If you are using a system that has
two CM’s, test each one after initial
set-up (steps a thru d).
Set CM RADIO switch to the RT it will be controlling.
l CONTROL must be at M; if it is at S, set CM FCTN to CONTROL; then
move INIT to DN, and release when CONTROL moves to M.
Check displays for initial RT set-up:
RF must be at LO.
RT MODE must be at SC.
CHAN must be at 0.
COMSEC must be at PT (VAR must be blank).
If CHAN and VAR show "F7”, move INIT switch to UP; then release; "F7”
must change to "Ud” (update). If CHAN and VAR show "Ud”, the RT is
setting up (initial set-up may take up to 6 seconds). All displays must show
as described in step f after "Ud” goes off.
