Connecting to your Vehicle’s Power

Follow these steps to power the HTX-242 in your vehicle.

1.Connect the black wire to your vehicle battery’s negative (–) terminal or to a metal part of the vehicle’s frame. Be sure the metal part is not insulated from the vehicle’s frame by a plastic part.

2.Connect the red wire to a source of voltage that turns on and off with the ignition and that can handle the transceiver’s 10-amp maximum power draw.

Or, if you do not want the HTX-242 to turn on and off with your vehicle’s ignition, connect the red wire directly to the battery’s positive (+) terminal.

!Note: You might need to connect the red wire directly to the battery if you experience ignition noise.
