ADDENDUM: Installation of
2.4GHZ Wireless Microphone System (Optional)
If your department opted for our new 2.4ghz wireless microphone system,
congratulations. This is an incredible wireless microphone with excellent
range and clarity. The installation is easy and straight forward.
All of the wires are labeled from the factory. For this installation, some wires
will not be used and 1 other will be optional.
First, find a suitable place in the vehicle for the base station/receiver. A bracket is
included. It should be mounted in an easily accessible position. Be sure there is room to
easily insert and remove the transmitter in the cradle.
Connect the RED wire(labeled PWR) to a positive 12v source and the BLACK(labeled
PWR GND) to a ground.
There are 3 wires that will
not
be used for this installation: small white wire labeled
‘Mute Indication’; small black wire labeled ‘Trigger Gnd’; and small orange wire labeled
‘ TX indication’. These wire can be cut or tucked away.
1 wire’s use is optional; the small brown wire labeled ‘ Trigger REC’. If this wire is
connected to the Brown trigger lead from the back of the DVR, then the DVR will begin
recording when the talk button on transmitter is active and lit. In other words, if an officer
keeps their mic on stand-by when not in use, then when they activate with the ‘talk’
button to begin transmitting it will activate the recorder. This is useful when outside the
car and not recording, and then a situation comes up and the officer needs to activate the
recorder remotely to begin recording. This is only optional and should be left up to the
department or officer of the vehicle.
The last wire is the large black one labeled ‘Audio Out’. This will be plugged into the
Red RCA lead coming from the back of the DVR. It is part of the same cable where the
camera is plugged in.
Now plug the antennae into the gold plug on the top of the cradle and secure by
tightening the lock nut. Run the wire down under the dash or other hidden location,
somewhere toward the front of the vehicle. Velcro or 2 sided tape works great for
securing the antennae end to a flat surface on the vehicle.
