Mobile Installation - Realistic TRC-490-18 Owner's Manual

MOBILE INSTALLATION
For Negative Ground Electrical Systems: Connect the Black with stripe wire (with in-line fuse holder) to
the Accessory terminal on the ignition switch of your vehicle. Make a good mechanical and electrical
connection to the frame of the vehicle for the black (negative) wire. Set DC-AC switch to the DC
position.
For Positive Ground Electrical Systems: Connect the Black wire to the Accessory switch "hot" terminal
and connect the Black with stripe Wire to the metal frame of the vehicle. Thus, Black always goes to
negative (-) and Black with stripe! always goes to positive (+). Set DC-AC switch to the DC position.
You can use an auto accessory plug (Radio Shack Catalog No. 274-331) to connect your Transceiver to
the vehicle's cigarette lighter socket. However, it is better to connect the DC power cord directly to the
accessory terminal of the ignition switch. This will prevent unauthorized usage of the Transceiver, and
will also prevent you from leaving the Transceiver on unintentionally.
