Be sure you connect the adapter as instructed, and disconnect the adapter from the AC outlet before you disconnect it from the system. Otherwise, the unconnected plug might touch some metal and dam- age the adapter.

Follow these steps to power the system from an AC outlet.

1.Insert the adapter's barrel plug into the system’s DC 9V jack.

2.Plug the adapter into a standard AC outlet.

Using an adapter that does not meet these specifications could seriously damage the system or the adapter.

Be sure you connect the adapter as instructed, and disconnect the adapter from the cigarette lighter be- fore you disconnect it from the sys- tem. Otherwise, the unconnected plug might touch some metal in the vehicle and damage the adapter and/or the vehicle’s electrical sys- tem.

Follow these steps to power the system from your vehicle’s battery:

1.If necessary, set the adapter's volt- age switch to 9V.

2.Insert the adapter’s barrel plug into the system’s DC 9V jack.

3.Plug the adapter’s large plug into the vehicle’s cigarette lighter socket.

Using Vehicle Battery Power

You can power the speakers from your vehicle's battery with a DC adapter (not supplied), available at your local Ra- dioShack store.

Cautions:

Your vehicle must have a 12-volt DC, negative-ground electrical sys- tem.

You must use a DC adapter that supplies 9 volts and delivers at least 500 milliamps. Its center tip must be set to positive, and its plug must cor- rectly fit the system’s DC 9V jack.
