an alcohol-distilled water solution. Commercial cleaning solutions may cause

darnage or corrosion. Always brush stylus from back to front; never

TO PRESERVE STYLUS LIFE:

1. Follow turntable or tone arm instructions when adjusting antiskating

force.

2. Do not handle the tone arm while it

cause the arm to sweep across the record.

If it is necessary to manually place the tone arm in the record groove

while turntable is rotating, release it as soon as the stylus engages the

record groove.

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 manufac-

turer recommends.

Take care to properly insert the stylus into the cartridge assembly and the cartridge and shell assembly into the tone arm receptacle.

Use proper vertical tracking force setting for each cartridge.

Do not use badly warped, cracked or imperfect records.

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