Cause:
The voltage in the power supply section is abnormal.
Supplementary information:
The abnormal voltage is displayed in % based on
5V as 100%.
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.
Cause:
DC output of the power amplifier is abnormal.
Supplementary information:
The abnormal voltage is displayed in % based on
5V as 100%.
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 menu list described in the section of the startup screen appears on the superimposed screen
and 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.
• Operation procedure of DIAG menu and SUB-MENU
There are 18 MENU items, each of which has some SUB-MENU items.
DIAG menu selection
Main unit: Select the menu using (Forward) and
(Reverse) keys of PRESET/
TUNING located in the sealing panel.
Remote control unit: Select the menu using (Forward) and (Reverse) keys.
SUB-MENU selection
Main unit: Select the sub-menu using (Forward) and (Reverse) keys of PROGRAM
located in the sealing panel.
Remote control unit: Select the sub-menu using (Forward) and (Reverse) keys.
• 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 has occurred previously can be defined as long as the backup data has
been stored.
The history of the protection function is cleared when DIAG is cancelled by selecting PRESET RESERVED (Memory
initialized) of DIAG menu No.10 or when the backup data is erased.
