Protecting The Disc; Troubleshooting - Hitachi AX-M68D Operating Instructions Manual

Protecting the Disc

1. To keep the disc clean, please don't touch the disc's surface when you are holding it. You should hold
the edge. (See fig. 1)
2. If the disc is dirty, it will affect the sound quality. Please use a clean, soft cloth to wipe the disc
from the centre to the edge (see fig.2). (Don't wipe the disc around the outside using a circular
motion.)

7. Never use benzene, thinners, record cleaner fluid or anti static spray.
