MAINTENANCE

Replacing a fuse
This amplifier requires a fuse with the proper rating for protection from
power surges and short circuits. If the amplifier suddenly turns off or will
not turn on. the fuse is properly blown.
• Let the amplifier cool down and see
if it start again before you assume a
fuse needs to be replaced.
• Unplug the amplifier from the AC
outlet.
• Turn the fuse holder cap and pull out
the cap.
• Remove the old fuse and replace it
with an identical one.
CAUTION : Never use a fuse with a higher rating.
