Installation Notes

Installation should be performed by a qualified electronics technician familiar with A/V equipment disassembly. Always disconnect the unit from AC power and allow capacitors to discharge before beginning any service work. Front panel disassembly typically requires small Phillips and flathead screwdrivers; consult the service manual for the specific unit.
