Replacing the Fuse

This crossover uses a 1-amp, blade-type fuse
for protection from power surges or a short cir-
cuit. If the POWER indicator turns off or does
not turn on, replace the fuse with a new one of
the same size and type.

1. Be sure the power source is off.

2. Firmly grasp the fuse's plastic end and

pull it out.

3. Holding the new fuse's plastic end, push

it firmly into place.
