Good manual. It is complete and of high quality, both text and graphics. The schematics are with the original big size, so it can be viewed or printed without any loss of resulution and sharpness.

8.6 PRECAUTION ON REPLACEMENT OF THE POWER SUPPLY UNIT
A
Attachment of the housing wire
The housing wire (J126) is attached to the P11 terminal of the POWER SUPPLY unit. As the housing wire is not provided with the POWER SUPPLY unit for service, when replacing the POWER SUPPLY unit, remove the housing wire (J126) from the old one and attach it to the new one. NEVER turn on the unit before replacement, as doing so may damage the PC boards or the product. Note: The wiring shown in the photo is different from the actual power supply unit, because the product in the photo is a prototype.
