If using the cable that comes with the cigarette lighter adapter, simply connect
it to the cigarette lighter outlet. If you wish to make a permanent mount to a
power supply, cut the cable between the power supply box and the cigarette
lighter adapter. Attach the red (+) and black (-) wires to your external power
source. The input voltage range for external power is 9-18 VDC.
Caution: Do not bypass the power supply box or you will damage your unit
and void the warranty.
