RX-V3300/DSP-AZ2
RX-V3300/DSP-AZ2
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.
When there is a history of protection
function due to abnormal voltage in
the power supply section
Version (1 alphabet)
Voltage display in %
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.
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.
When there is a history of protection
function due to excessive heat sink
temperature
Version (1 alphabet)
Voltage display in %
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.13 described later.
