Model MXT100
Electrical and Rear Panel Connections
Refer to Rear Panel Connections for rear panel connector locations.
NOTE: Radio antenna is installed separately.
1. The power cord supplied with the MXT100 is equipped with a cigarette
lighter adapter for easy installation. Simply plug the connector into the
vehicle’s cigarette lighter. If a “hardwired” installation is desired,
connect the power cord to the vehicle’s electrical system as follows:
Connect the positive lead (RED wire with in-line fuse holder) to
either (a) the fuse block or (b) directly to the positive post of the
vehicle’s battery.
NOTE: The fuse block is usually the most convenient connection
point. The power cord positive lead can also be connected to the
Accessory terminal on the fuse block or ignition switch, so the
radio automatically turns off when the ignition is turned off.
Securely connect the ground lead (BLACK wire) directly to the
vehicle’s metal frame. A good direct metal-to-metal ground is
essential for optimum performance.
2. Connect the 2-pin plug-in connector of the power cable to the 13.8V DC
jack on the rear panel.
3. Attach the antenna cable to the ANT jack on the rear panel.
4. If desired, an optional external speaker (purchased separately) can be
connected to the EXT SPKR jack (see Using an External Speaker).
Connecting the Microphone
Insert the RJ11 connector into the front of the MXT100. Once the
microphone is connected, use a small tool to insert the strain relief.
The microphone bracket can then be attached to the vehicle dash or other
convenient location in a manner similar to the mounting bracket.
Using an External Speaker
The MXT100 provides a rear-panel jack for connection of an optional
external speaker (purchased separately).
