Replacing the drive belt

Remove the platter as described above and set the old belt
aside. Place the new belt around the drive platter of the turn-
table. with the textured (ground) side of the belt on the inside.
Then slip the belt around the Vario-pulley and inside the guide
fork. Finally, lower the platter onto the shaft and seCure with
the decorative center ring.

Stylus care

In normal use, every stylus is subject to wear and tear. We
recommend that yours be inspected periodically, and cer-
tainly after approximately 300 playing hours in the case of
diamond styli. Worn or damaged (chipped) Styli will grind the
modulation out of the grooves and damage your records. For
replacement, obtain only the stylus type recommended in the
Technical Data for your cartridge. lmitations can cause noticeable
loss in sound quality and rapid record wear.

Please keep in mind that the stylus and cantilever are ne-
cessarily quite delicate in order to provide quality perfor-
mance. They are extremely sensitive to harsh handling, ac-
cidental blows, etc. Take the cartridge in the holder to your
Dual dealer for inspection of the stylus. (Removal of cartridge
holder is described above).

Your Dual has a limited warranty of two years from date of
purchase against manufacturing defects or faulty parts.

Note. Only factory-authorized service stations should service
