1.Set the adapter’s voltage switch to 4.5V.

2.Line up the 5.5 mm outer diameter/2.1 mm inner diameter bar- rel plug with the adapter’s socket so it reads –TIP, and insert the plug into the socket.

3.Insert the barrel plug into the receiver’s DC IN 4.5V jack.

4.Plug the adapter into a standard AC outlet.

Using Vehicle Battery Power

To power the receiver from your vehicle’s battery, you need an op- tional DC cigarette lighter adapter, such as Cat. No. 270-1560.

Cautions:

•The DC cigarette lighter adapter must be capable of delivering 4.5 volts, its center tip must be set to negative, it must deliver at least 200 milliamps, and its barrel plug must properly fit the receiver’s DC IN 4.5V jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the receiver or the adapter.

•Always plug the DC cigarette lighter adapter into the receiver before you plug it into your vehicle's cigarette-lighter socket. Always unplug the adapter from the vehicle's cigarette-lighter socket before you unplug it from the receiver.

Follow these steps to power the receiver from your vehicle’s battery.
