Caution: The supplied power
cord has a polarized plug that fits
into the outlet only one way. If the
plug does not fit properly, turn it
over and try again. Do not force
it.
PREPARATION
Using AC Power
You can power the PA system using
the supplied AC cord.
Using Vehicle Battery Power
Cautions:
The cord’s plug must fit
the system's ~120V AC
You can power the PA system from a
vehicle’s 12V power source (such as
a cigarette-lighter socket) using the
supplied DC cord.
!
60Hz 60W jack. The sup-
plied cord meets these specifica-
tions. Using a cord that does not
meet these specifications could
damage the system or the AC
cord. You can order a replace-
ment cord through your local Ra-
dioShack store.
Cautions:
You must use a power
source that supplies 12V
!
DC and delivers at least
2500 mA. Its plug must fit the
system's DC 14.4V/2.5A jack. The
supplied adapter meets these
specifications. Using a cord that
does not meet these specifica-
tions could damage the system or
the adapter.
• Always connect the AC cord to
the system before you connect it
to AC power. When you finish,
disconnect the cord from AC
power before you disconnect it
from the system.
• Always connect the cord to the
system before you connect it to
the power source. When you fin-
ish, disconnect the DC cord from
the power source before you dis-
connect it from the system.
Set the amplifier to OFF. Plug the
power cord’s plug into the amplifier’s
~120V AC 60Hz 60W jack. Then plug
the other end of the cord into a stan-
dard AC outlet.
Set the amplifier to
OFF. Plug the DC
power cord’s barrel
plug into the DC
14.4V/2.5A
jack.
Then plug the other
end of the cord into
a standard DC source such as an au-
tomobile 12V accessory outlet.

CARE AND MAINTENANCE
To enjoy your PA system for a long
time:
In the Back of the PA System
1. Set ON/OFF to OFF and unplug it.
• Keep the system dry. If it gets it
wet, wipe it dry immediately.
2. Insert a flat-blade
screwdriver into
the fuse holder’s
cap located on
the back of the
amplifier, gently
press in the cap,
• Use and store the system only in
normal temperature environ-
ments.
• Handle the system gently and
carefully. Don’t drop it.
and
rotate
it
• Keep the system away from dust
and dirt.
counterclockwise
until the fuse cap
unlocks.
• Wipe the system with a damp
cloth occasionally to keep it look
new.
3. Remove the fuse holder’s cap
then pull out the fuse.
Modifying or tampering with the am-
plifier’s internal components can
cause a malfunction and invalidate its
warranty and void your FCC authori-
zation to operate it. If your amplifier is
not performing as it should, take it to
your local RadioShack store for assis-
tance.
4. If the fuse is blown (the inside
wire is broken), remove it and
replace it with a 1.5A/125V fuse.
5. Insert the fuse holder’s cap back
into the socket on the back of the
amplifier.
6. Carefully tighten the fuse holder’s
cap by pushing it in and rotating it
clockwise until it locks.
REPLACING THE FUSE
In the DC Cord
If the PA system stops operating
properly, you might need to replace
the fuse in the back of the system or
the in-line fuse in the DC cord.
1. Unplug the DC cord from the cig-
arette-lighter socket and then the
PA system.
2. Turn the cap counter clockwise to
open the plug, then remove the
fuse taking care not to lose the
tip.
Important: Turn off the PA system
and let it cool. Then try operating it
again before you replace the fuse.
Caution: Do not use a fuse with rat-
ings other than those specified. Doing
so might damage your amplifier.
3. Replace the fuse with a new fuse
of the same rating (3A/125V) and
type.
4. Replace the cap and turn it clockwise
to secure it closed.
