Sega products have warning display stickers, labels or printed instructions attached to or incorporated in the places where a potentially hazardous situation can arise. The warning displays are intended for accident prevention for the customers and for avoiding hazardous situations while performing maintenance and servicing work. There are some portions of the cabinet, which are subject to high tension voltage, etc., where accidents can be caused merely by touching the machine. When performing service work, be very careful of the warning displays. Especially, any complex repair or replacement work not mentioned herein, should be performed by those technical persons who have knowledge of electricity and are trained to perform such work. For accident prevention, caution any customers to avoid actions which might cause a hazardous situation.
