RADIO STATION LOCK-OUT
Radio station Lock-Out gives Fleet managers the ability to restrict AM/FM
playback. To enable operation, set acceptable stations into all the AM & FM
presets. If only one station is allowed, preset that same station into all presets of
either the FM or AM band. Once the stations are set, Press and hold both the
VOL/SEL (2) and BAND (3) buttons for 3 seconds. The display will scroll
“ENTER CODE”, at which time the user can enter a personal 4 digit code using
presets 1-6. Once entered, the display will show “LOCKED” giving the user
confirmation. The user will have access to only the AM & FM stations found in
presets 1-6. If the user attempts to change the station using the SEEK/TUNE
buttons, the display will scroll “ENTER CODE”. Entering the wrong code will
scroll “ERR CODE”. Once the user enters the correct code, the display will
show “UNLOCKED” and restore the radio to normal operation.
PA OPERATION
The VR-3000 has three PA Microphone inputs, 2 Dynamic & 1 Carbon
microphone input. All microphones have priority over all other audio modes and
MUTE the source audio being played when keyed. When the 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 input is the Primary, and the other input MIC 2 is the
Secondary. When the two are keyed simultaneously, the MIC 1 microphone will
always have priority over the MIC 2.
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 Volume/Select knob on the front
of theradio. 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.
