DC Power

With an optional DC adapter, such as Radio Shack Cat. No. 270-1562, you can power the receiver from your vehi- cle’s battery.

Cautions:

•You must use a DC adapter that supplies 6 volts with the center tip set to negative. It must deliver at

least 400 milliamps, and its plug must properly fit the receiver’s DC IN 6V jack. Using an adapter that does not meet these specifica- tions could damage the receiver or the adapter.

•To protect your vehicle’s electrical system, be sure the adapter is connected to the cigarette-lighter socket only when it is also con- nected to the receiver.
