KCU 951 CONTROL DISPLAY UNIT OPERATION
KCU 951 CONTROLS
The controls on the KCU 951 are: OFF/VOLUME knob, SQUELCH
knob, CLARIFIER knob, MODE button, FREQ/CHAN button, PGM
(program) switch, STO (store) switch and concentric
Frequency/Channel control knobs.
OFF/VOLUME
This knob turns the system off and on and controls volume.
Clockwise rotation past the first click turns the system on. Further
rotation increases audio level. Good operating practice suggests that
the system shouldn’t be turned on until after starting the engines. It
takes about two minutes for the KHF 950/990 to warm up. Until then,
no frequencies is displayed.
