Not applied to this model.
DC/PS (protection detection)
DC:
DC detect protection value
Normal value: 19 to 51 (Reference: 5V = 100%)
PS:
Power supply voltageprotection value
Normal value: 54 to 84 (Reference: 5V = 100%)
When the value is outside of the normal range, the pro-
tection function works to turn off the power.
3. AD DATA CHECK
With this sub-menu used, the key scanning, A/D value of
the voltage at the abnormality detect (protection) port, etc.
are displayed. The A/D conversion value is displayed in %.
The state before audio signal processing is kept.
When K0/K1 menu is selected, keys become nonoperable
due to detection of the values of all keys.
However, it is possible to advance to the next sub-menu by
turning the INPUT of the main unit. When using this func-
tion, note that turning the INPUT more than 2 clicks will
cause the volume value to change.
* The numeric value in the diagram is for reference.

THM (temperature detection)
When the value is outside of the normal range, the protec-
tion function works to turn off the power.
500% display of the voltage based on the temperature de-
tected value. Reference voltage: 5V
* For RX-497, only R ch is effective.
K0/K1
This is the A/D value of the panel key input ports KEY0 and
KEY1 (microprocessor). The table below shows the A/D
value obtained when each key is pressed. When the value
is not within the standard value range, no correct operation
is provided. Referring to the table below, check the value of
each voltage dividing resistor of each key, solder condition,
etc.
