8. MANUAL TEST
The built-in noise generator of DSP outputs the test noise through the channels specified by using the sub-menu.
8-1. TEST ALL
The test noise is output to all channels.
9. A/D DATA CHECK
This menu is used to display the A/D conversion value of the microprocessor which detects panel keys and protection
functions by using the sub-menu.
When "9-5. K1/K2" menu is selected, keys become inoperable due to detection of the values of all keys.
However, it is possible to advance to the next menu by turning the "VOLUME" knob.
