When there is a history of protection
function due to abnormal DC output
Version (1 alphabet)
Cause: DC output of the power amplifier is abnormal.
Turning on the power without correcting the abnormality
will cause the protection function to work 3 seconds later
and the power supply will be shut off.
Cause: The temperature of the heat sink is excessive.
Supplementary information: The abnormal voltage is
displayed in % based on 5V as 500%.
Turning on the power without correcting the abnormality
will cause the protection function to work 1 second later
and the power supply will be shut off.
* Additional causes of protection can be due to loose
connections, associated components, CPU, etc.
* For the protection voltage value, refer to DIAG menu
No.10 described later.
• Display during menu operation
During the DIAG operation, the function at work is
indicated on the FL indicator. The contents displayed
during the function operation are described in the later
section on details of functions.
• History of protection function
When the protection function has worked, its history is
stored in memory with a backup. Even if no abnormality
is noted while servicing the unit, an abnormality which
