SERVICING
We recommend that you read the SAFETY NOTICES section thoroughly before beginning service.
This VGM uses complex electronic components that can be very SENSITIVE to static electricity.
The following precautions must be observed and followed prior to handling any of the electronics.
1. Ensure that the AC power to the VGM is turned OFF prior to servicing the electronics.
2. Discharge any static electricity build up in your body by touching the VGM cabinet metal base.
This must be done BEFORE touching or handling the electronic assemblies.
3. Store the electronic assemblies in an anti-static area. Anti-static bags are to be used to store
VGM electronic assemblies. Reuse the bag to store removed boards during service.
4. DO NOT remove or connect any electronic assemblies when the cabinet power is ON. Doing
so will damage the electronic assemblies and void the warranty.
5. Always replace ground wires, shields, safety covers, etc. when maintenance or service is
completed. Ensure that all ground and mounting screws are installed and tightened firmly.

Cabinet (Top Cover)
Switch off power to the VGM and unplug from AC power. Insert key or keys into rear door locks. Turn
each key clockwise to unlock. Lift the access door up from the cabinet. Reach inside the rear of the
cabinet to loosen and remove the thumbscrews and washers used to hold the cover in place. Store
screws and washers in a safe place. Slide the cover forward approximately 1/2 inch (12 mm) until it
stops. Lift up both side panels and remove the cover from the base. Set the cover in a safe place.
