Using Vehicle Battery Power

To power the receiver from your vehi- cle’s battery, you need an optional DC cigarette lighter adapter, such as Cat. No. 273-1802.

Caution: You must use a DC

!cigarette lighter adapter that supplies 6 volts DC and deliv-

ers at least 300 mA. Its center tip must be set to negative and its plug must fit the receiver's DC IN 6V jack. The rec- ommended DC cigarette lighter adapt- er meets these specifications. Using an adapter that does not meet these specifications could damage the re- ceiver or the adapter.

Caution: Always plug the DC ciga- rette lighter adapter into the receiver before you plug it into your vehicle's cigarette-lighter socket. Always un- plug the adapter from the vehicle's cigarette-lighter socket before you un- plug it from the receiver.

Follow these steps to power the re- ceiver from your vehicle’s battery.

1.Set the DC cigarette lighter adapter’s voltage switch to 6V.
