Classe Audio CAV-100 Owner's Manual page 17

If the protection circuit of the unit is triggered or any of the
fuses has blown, the front panel power LED will go to
BLINKING GREEN mode, indicating a "fault" condition. Turn
OFF the CAV-100 Multichannel Power Amplifier
immediately. Only after the fault has been clearly identified
and corrected should you attempt to re-start the unit. If the
amplifier returns to protection mode immediately, or it
appears the main AC fuse has blown DO NOT continue
troubleshooting. Contact your local dealer for further
assistance.
