P1-8. KEY1/KEY2
Panel key is detected.
When the A/D conversion value of the panel key becomes out of the specified range, normal operation will not
be available.
In that case, check the constant of voltage dividing resistor, solder condition, etc. Refer to table.
* When "P1-8. KEY1/KEY2" 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 pressing the "SCENE RADIO" (forward) key or
"SCENE NET" (reverse) key on the remote control.
