4 x 25 Watt Trunk Mount Amplifier
(120-1976)              Care and Maintenance          Faxback Doc. # 16986

Your Radio Shack 4 X 25 Watt Trunk Mount Amplifier is an example of
superior design and craftsmanship.  The following suggestions will help you
care for your amplifier so you can enjoy it for years.

    Keep the amplifier dry.  If it gets wet, wipe it dry immediately.
    Liquids can contain minerals that corrode electronic circuits.

    Use and store the amplifier only in normal temperature environments.
    Temperature extremes can shorten the life of electronic devices and
    distort or melt plastic parts.

    Handle the amplifier gently and carefully.  Dropping it can damage
    circuit boards and cases and cause the amplifier to work improperly.

    Keep the amplifier away from dust and dirt, which can cause premature
    wear of parts.

    Wipe the amplifier with a damp cloth occasionally to keep it looking
    new.  Do not use harsh chemicals, cleaning solvents, or strong
    detergents to clean the amplifier.

Modifying or tampering with the amplifier's internal components can cause
a malfunction and invalidate your amplifier's warranty.  If your amplifier
is not performing as it should, take it to your local Radio Shack store
for assistance.

REPLACING THE FUSES

If the amplifier shuts down, you might need to replace the power wire's
10-amp tube-type fuse (such as Cat. No. 270-1072, not supplied), the 10-
amp blade-type fuse (such as Cat. No. 270-1081, not supplied) on the back
panel, or both fuses.

CAUTIONS:  Do not use fuses with ratings other than those specified here.
           Doing so might damage your amplifier.

           After replacing a fuse, let the amplifier cool down before you
           turn it on again.

Turn off your autosound system, then disconnect your vehicle battery's 
negative (-) terminal.

Replacing the Tube-Type Fuse

1.  Grasp the two ends of the power wire's fuse holder and twist them
    counterclockwise, then pull the ends apart.

2.  Insert a new 10-amp, tube-type fuse into the longer of the two fuse-
    holder's ends, then grasp the fuse-holder's two ends, push them in and
    twist them clockwise to secure them.

Replacing the Blade-Type Fuse

1.  Grasp the fuse's plastic end and pull it out.

2.  grasp the new fuse's plastic end and simply push it in.
