code, the display will show “UNLOCKED” and restore the radio to normal operation.

PA OPERATION (microphone sold separately)

The ST-4000 has three PA Microphone inputs, 2 Dynamic & 1 Carbon. All PA
microphones have priority over other audio modes, and will MUTE the source audio
being played when keyed. When a PA is triggered, the front display will show
MIC 1, MIC 2 or MIC, until the trigger is un-keyed. Once released, it will return
to the previous source mode at the previous volume level.

The Dynamic MIC 1 PA input is the Primary and the other PA input MIC 2 is the
Secondary. When the two are keyed simultaneously, the MIC 1 PA microphone
will always have priority over the MIC 2 PA.

All PA inputs operate regardless of radio power status, as long as both ACC and
Battery power is applied to the radio. The volume levels of MIC 1 & MIC 2 can be
independently adjusted from the radio’s main VOL/SEL knob on the front of the
radio. Once released, their final volume levels are stored into memory as default for
the next time they are keyed. The volume levels of MIC 1 & MIC 2 can only

be
adjusted when they are keyed. The volume of the Carbon microphone, MIC, is only
adjustable on the microphone itself and therefore its level is not saved. A rear
view of the radio’s PA pin connections are shown below:

NOTE:
For easy viewing at night, the backlighting will always

be on when ACC +12V
switched power is applied. Backlighting will only shut off when the switched ACC
+12V power is removed.
