Note: If you do not plan to use the sys- tem for several days, or if you plan to power the system using only AC or DC power, remove the batteries.
Using AC Power
To use AC power, plug the supplied power cord into the AC 120V 60Hz jack on the back of the CD-3321. Then plug the cord’s other end into a standard AC outlet.
illus
Note: The plug’s blades are polarized (one blade is wider than the other) and it fits only one way. If the plug will not fit easily, turn it over and try again. Do not force it.
Caution: Always unplug the power cord from the AC outlet before you unplug it from the CD-3321.
Using Your Vehicle’s Cigarette- Lighter Socket
To power the CD-3321 from your vehi- cle’s cigarette-lighter socket, you need a DC adapter (not supplied), such as Cat. No. 270-1528.
Cautions:
•You must use a DC cigarette-lighter adapter that supplies 12 volts and delivers at least 1 amp. Its center tip must be set to positive, and its plug must correctly fit the CD-3321’s DC 12V jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the CD-3321 or the adapter.
•Unplug the adapter from your vehi- cle’s cigarette-lighter socket when you turn off the ignition. This pre- vents your vehicle’s battery from being drained if you leave the CD- 3321 on when you turn off the igni- tion.
•Always plug the DC adapter into the CD-3321 before you plug it into your vehicle’s cigarette-lighter socket, and unplug the adapter from your vehicle’s cigarette-lighter socket before you unplug its barrel plug from the CD-3321.
