2.Use the following tools and measuring instruments.

•Digital multi meter

•Regulated dc power supply (two sets)

•Ampere meter

•Laser power meter

•CD adjustment disc TDYS-1 (Part No. : 4-963-646-01)

•MD1/HiMD1 hybrid adjustment disc MDW-74/GA2

•Hi-MD3 adjustment disc HMD1GSDJ (Part No. : 8-892-388-38) *1

•Remote commander in accessories (with LCD)

•AC adapter in accessories

*1) Hi-MD3 adjustment disc (HMD1GSDJ) is consumable. Therefore if it is used 400 times, exchange it for a new.
