EMG Panic Button (if wired for use in your vehicle)
1) The EMG or Panic Button can be programmed to do many things but may
not be connected in your vehicle. Check with your technical department to
understand what this button will control before you use it.
2) In Record mode: Press the EMG button on the transmitter, a beep will sound
and the relay will be triggered at the receiver.
3) In Standby mode: Press the EMG button on the transmitter, a beep will
sound, the green In-Use indicator will blink and the relay will be triggered at
the receiver.
Disabling the Beep Sound On the Transmitter
1) All of the audible beep signals on the transmitter can be disabled by setting
the BEEP switch to the off position.
Auto Talk (if video recording equipment supports)
1) The Auto Talk feature is used to turn on the microphone whenever the video
recorder is turned on. Some video record units can be triggered by other
events (lights and siren being turned on etc.) and Auto Talk ensures the
microphone starts recording at the same time. The transmitter must be
turned on and in standby mode.
2) A +5V signal on the Auto Talk line means the microphone is off.
3) 0V or ground on the Auto Talk line turns on the microphone
INSTALLATION
1. Wire the un-terminated signal wires to the control unit according to the signal chart. A 5
Amp fast blow fuse is recommend in the 12VDC power supply line to protect the
equipment.
