Care
To enjoy your MPA-50 40-Watt PA Am-
plifier for a long time:
• Keep the amplifier dry. If it gets wet,
wipe it dry immediately.
• Use and store the amplifier only in
normal temperature environments.
• Handle the amplifier gently and
carefully. Don’t drop it.
• Keep the amplifier away from dust
and dirt.
• Wipe the amplifier with a damp cloth
occasionally to keep it looking new.
Modifying or tampering with the amplifi-
er’s internal components can cause a
malfunction and invalidate its warranty.
If your amplifier is not performing as it
should, take it to your local RadioShack
store for assistance.
REPLACING THE FUSE
The power fuse protects your amplifier
from power (voltage or current) surges
when operating it from an AC power
source. If the POWER indicator does not
light when you press
POWER
, check the
fuse and replace it with one of the same
size and type. (A spare fuse is included.)
Follow these steps to replace the ampli-
fier’s fuse.
1. Unplug the amplifier’s power cord.
2. Using a flat-blade screwdriver, push
and turn the fuse holder’s cap coun-
terclockwise until the fuse holder
pops out.
3. Remove the fuse holder and replace
the fuse.
4. Slide the fuse holder back in place
then, using a flat-blade screwdriver,
push and turn the fuse holder’s cap
fully clockwise to secure it.
