P1. SYSTEM MONITOR
This menu is used to display the A/D conversion value of the microprocessor which detects panel keys of this unit and
protection functions by using the sub-menu.
When "P1-7. KEY1/KEY2" sub-menu is selected, keys become non-operable due to detection of the values of all keys.
However, it is possible to advance to the next sub-menu by pressing the "SCENE RADIO" (forward) or "SCENE CD"
(reverse) key of the remote control.
* Numeric values in the figure are given as reference only.

Power amplifier DC (DC voltage) output is detected.
The voltage at 1 pin (DC_PRT) of IC902 is displayed.
Normal value: 32 to 74 (Reference voltage: 3.3 V=255)
* If DC becomes out of the normal value range, the protection function works to turn off the power.
