2. Errors checking mode (Displaying the protection history)
2.1. Operation specifi cations
Error mode (Displaying the protection history):
When started up, the error information is displayed.
Starting up:
●All model commonness
With the "STATUS" and "MULT EQ" buttons pressed, press the "ON/STANDBY" button to turn the power on. The error
(protection history display) mode is set.
Now, press the "STATUS" button to turn on the FL display.
2.2. About the display on the FL display
When the "STATUS" button is pressed after setting the error (protection history display) mode, a history like the one
shown below is displayed, depending on the conditions.
(1) Normally (when there has been no protection incident)
FLD
NO PROTECT
(2) For ASO (when the last protection incident was ASO protection)
FLD
PRT:ASO
Cause: The line between speaker terminals is shorted, or use speakers having impedance less than that specifi ed.
Supplementary information: As the excess current is detected after operation of the speaker relay, the shorted
speaker terminal and the connected speaker can be identifi ed.
Turning on the power without correcting the abnormality will cause the protection function to work about 5 seconds
later and the power supply will be shut off.
(3) For DC (when the last protection incident was DC protection)
FLD
PRT:DC
Cause: DC output of the power amplifi er is abnormal.
Turning on the power without correcting the abnormality will cause the protection function to work about 5 seconds
later and the power supply will be shut off.
(4) For THERMAL (when the last protection incident was THERMALprotection)
FLD
PRT:THERMAL
Cause: The temperature of the heat sink is excessive.
Turning on the power without correcting the abnormality will cause the protection function to work about 5 seconds
later and the power supply will be shut off.

Additional causes of protection can be due to loose connections, associated components, Microprocessor, etc.
When the "STATUS" button is pressed again after the above protection history is displayed, the normal display reappears.
