Its center tip is set to negative. Using an adapter that does not meet these specifications could seriously damage the radio or the adapter.

Be sure you connect the AC adapter to the radio before you connect it to the AC outlet, and then disconnect it from the AC outlet before you disconnect it from the AC outlet before you disconnect it from the radio. Otherwise, the unconnected plug might touch some metal and damage the adapter.

Follow these steps to power the radio from a standard AC outlet.

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

2.Insert the green-tipped Adaptaplug's black end into the AC adapter's cord so it reads TIP NEG.

3.Insert the Adaptaplug's other end into the radio's DC 4.5V jack.

NOTE: Connecting an AC adapter automatically disconnects internal battery power.

4.Plug the adapter into a standard AC outlet.

USING VEHICLE BATTERY POWER

You can power the radio from a vehicle's battery using an optional DC adapter, such as Radio Shack Cat. 270-1560 (not supplied)

CAUTIONS: The vehicle must have a 12-volt DC, negative-ground electrical system.

The recommended DC adapter supplies 4.5 volts, delivers 300 milliamps, and its plug correctly fits the radio's DC 4.5V jack. Its center tip is set to negative. Using an adapter that does not meet these specifications could seriously damage the radio or the adapter.

Be sure you connect the DC adapter to the radio before you con- nect it to the cigarette-lighter socket, and then disconnect it from the radio. Otherwise, the unconnected plug might touch some metal and damage the adapter.

Follow these steps to power the radio from a vehicle's battery.

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