RECOMMENDED STYLUS CLEANING: Use a camel's hair brush (No. 2 size
or smaller), trimmed to

alcohol-d~st~lled water solution Commercial cleaning solutions may cause

an
5tylus damage or
brush or wipe stylus from front to back or side to side.

TO PRESERVE STYLUS

1. Follow turntable or tone arm instructions when adjusting antiskating
force.

2. Do not handle the tone arm while it is in operation since this may
cause the arm to sweep across the record.

3.

If ~t is necessary to manually place the tone arm in the record groove
wh~le turntable is rotating, release it as soon as the stylus engages the
record groove.

3.

Correct improper set-down adjustment or malfunction of the turntable
changing mechanism to prevent the stylus from striking the edge of the
turntable or record. Do not stack more records than turntable manufac­turer recommends.

5.

Take care to properly insert the stylus into the cartridge assembly and

the cartridge and shell assembly into the tone arm receptacle.

6. Use proper vertical tracking force setting for each cartridge.

7.

Do not use badly warped, cracked or imperfect records.

8.

When dusting the turntable protect the stylus with the stylus guard.
