NSTALLATION
When routing cables from the cab to the front of vehicle, fasten the
cables to fixed parts of your vehicle with tie wraps. Tie wraps are
available from Heath as P/N 9996350 for 4” (per 1,000) and P/N
0419180 for 8” (each). Be sure to route cables away from exhaust
components and shift linkages.
The OMD requires six amperes of continuous current. So connect
the system power cable to the vehicle’s battery. Do not connect
the system power cable to the cigarette lighter or anywhere else
that is not rated for at least six amperes. When connecting power,
polarity must be observed. If the positive and negative leads are
reversed, the fuse will blow immediately. The red wire should be
connected to the positive terminal and the black wire connected to
the negative terminal of the battery.
Note:
Connect the battery cable up last. Be sure that the receiver cable is
connected prior to making the battery connection. Damage to the
electronics may occur if not properly connected
Display installation:
The requirements for installing the display include mounting the
display at an operator friendly height and position and then plugging
in the display cable. A floorboard mounting pedestal or a dash-
board console are two possible mounting methods. These types of
devices are available from suppliers of cellular phone equipment.
