OPERATOR’S CONTROLS, INDICATORS, AND CONNECTORS
Control-monitors are used in some vehicles. They enable the remote control of up
to two mounting adapters with up to three RT.
1. J1 connector. Cabled to main
mounting adapter: RADIO switch
position 1 selects RT in position A of
mounting adapter: position 2 selects
RT in position B.
2. J2 connector. Cabled to second
mounting adapter (when used);
RADIO switch position 3 selects RT in
position A of second mounting adapt-
er.
CM (front view)
3. DIM control. Adjusts brightness of displays. Turn DIM right (clockwise) to brighten
displays; turn it left (counterclockwise) to dim displays. Turn DIM fully left when
you are wearing night-vision goggles.
4. INIT (initiate) switch. Used with FCTN switch to change functions of RT and
CM. Moving INIT to UP makes FCTN position’s display marker move right: moving
INIT to DN (down) makes it move left; function of RT controlled is changed accord-
ingly. When FCTN is at CHAN, moving INIT to UP or DN makes display num-
ber increase or decrease; RT channel is changed accordingly.
5. FCTN (function) switch. Used with INlT switch to change functions of RT and CM.

TEST. Only used to run CM self-tests. Displays show results. Tests will contin-
ue until FCTN is moved out of TEST.
RF. Used to set power output of RT. INIT switch is used for adjusting.
RT MODE. Used to set RT mode, including power off. INIT switch is used for
adjusting. RT MODE display shows operating mode.
CHAN (Channel). Used to select RT channel (including MAN and CUE) and
FH hopset. INIT switch is used for selecting. CHAN displays shows channel
selected. 0 on display indicates MAN (manual). C on display indicates CUE.
VAR (variable), Used to select COMSEC variables.
COMSEC. Used to select RT COMSEC mode (plain or cipher text).
CONTROL. Used to change CM operation from stand by (S) to main (M).
When two units are used, only one will be on main (M) at any one time. The
other will be on stand by (S). The main (M) unit controls the RT. The INIT
switch is used to switch unit from S to M. CONTROL display shows operating
condition.
6. RADIO switch. Selects RT to be controlled. Positions 1 and 2 are for the RT in
positions A and B of mounting adapter having two RT. Position 3 is for the
RT in position A of the second mounting adapter (when used).
7. J3 connector. Cabled to J3 of second CM (when used).
