11. AD DATA

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 % (ref-
erence voltage of 5V as 100%). The state before audio sig-
nal 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 VOLUME of the main unit. When using this func-
tion, note that turning the VOLUME more than 2 clicks will
cause the volume value to change.
* The numeric value in the diagram is for reference.

DC/PS (protection detection)

DC detect protection value
DC:
(Normal value: 1 to 13)
PS: Power supply voltageprotection value
(Normal value: 22 to 47)
When the value is outside of the normal range, the pro-
tection function works to turn off the power.

THM/Fan

The temperature detected value
THM:
When the value is outside of the normal range, the
protection function works to turn off the power.
500% display of the voltage based on the tempera-
ture detected value. Reference voltage: 5V
