TROUBLESHOOTING

NOTICE: The term VGM refers to the video game machine.

CAUTION: This VGM uses complex electronic components that are very sensitive to static electricity. Observe the following precautions before handling VGM electronics. Failure to do so may void your warranty and could damage electronic assemblies.

•Before servicing electronics, turn off AC power to the VGM. Wait for capacitors to discharge.

•Before touching or handling electronic assemblies, discharge static electricity on your body. To discharge this static, begin by connecting the line cord to a grounded outlet. Don’t turn on the VGM! Next, touch the safety ground stud of the power supply chassis.

•Store electronic assemblies in an anti-static area. Use anti-static bags to store or transport VGM circuit boards. Transport the hard drive in its shipping container.

•Don’t remove or connect electronic assemblies when cabinet power is on. Otherwise, you’ll damage electronic assemblies and void the VGM warranty.

•After you complete maintenance or service, replace ground wires, shields, safety covers, etc. Install and tighten ground and mounting screws.
