PRECAUTIONS FOR INSPECTIONS AND REPAIR WITH POWER OFF

Before beginning repair work after turning OFF the main switch, be sure to first remove CN932 (EHBP) of the power
board. When assembling the equipment, be sure to plug this connector last.

This is because, even with the main switch turned OFF, electric charges stilt remain in the smoothing capacitor in
the power board. Therefore, if another flexible board is inserted or removed, a terminal of the power supply may
short an adjacent terminal while destroying the device.
