REPLACING A FUSE
If the amplifier shuts down but the red PROTECTION indicator does not
light, you might need to replace the power wire's 15-amp tube-type fuse
(Cat. No. 270-1073), the blade-type fuse (Cat. No. 270-1082), or both
fuses.
Follow these steps to check a fuse and replace it, if necessary.
1. Turn off your sound system.
2. Disconnect your vehicle battery's negative (-) terminal
3. To remove the red power wire's fuse, grasp the two ends of the fuse
holder and twist them counterclockwise, then pull the ends apart.
To remove the front panel's automotive fuse, grasp the fuse's plastic
end and pull it out.
4. Remove and replace the fuse.
Caution: Do not use a fuse other than the specified fuse. Doing so
might damage your amplifier.
5. Grasp the two fuse-holder's ends, push them in and twist them
clockwise.
6. Let the amplifier cool down before you restart it.
