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-vo lt
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.
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.
OPERATION
Notes:
• Be sure the audio sources power is
off and its volume control is set to its
minimum level.
• If the audio source is stereo, the
speaker with the built-in amplifier is
the right speaker.
1. Insert the speaker system's 1/8-inch
miniplug into your audio source's
headphone jack.
