USING VEHICLE

BATTERY POWER

You can power your Concertmate 575 from your vehicle’s cigarette lighter socket using a DC adapter (not sup- plied), such as RadioShack Cat. No. 270-1560.

Cautions:

•You must use a DC adapter that supplies at least 7.5 volts and delivers at least 300 milliamps. Its center tip must be set to negative, its voltage switch must be set to 7.5 volts, and its plug must cor- rectly fit the Concertmate 575’s DC 7.5V jack. The recommended adapter meets these specifica- tions. Using an adapter that does not meet these specifications, or using the recommended adapter at a different voltage setting, could damage the Concertmate 575 or the adapter.

•Always plug the DC adapter into the Concertmate 575 before you plug it into the cigarette lighter socket. Always unplug the DC adapter from the cigarette lighter socket before you unplug it from the Concertmate 575.
