Optimus CD-3321 - Manual (Page 7)

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.
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.
