To enjoy your MPA-40 20-Watt PA Amplifier 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 amplifier'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 amplifier's fuse.

1.  Unplug the amplifier's power cord.

2.  Using a flat-blade screwdriver, push and turn the fuse holder's cap
    counterclockwise 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.
