RECOMMENDED STYLUS CLEANING: Use a camel's hair brush (No. 2 size
or smaller), trimmed to approximately 6 mm (1/4 in.), dipped in alcohol o r
an alcohol-distilled water solution. Commerc~al cleaning solutions may cause
stylus damage or corrosion. Always brush stylus from back to front; never
brush o r wipe stylus from front to back or side t o side.
TO PRESERVE STYLUS LIFE:
1. Follow turntable o r tone arm instructions when adjusting antlskating
force.
2. D o not handle the tone arm while i t is i n operation since this may
cause the arm to sweep across the record.
3. I f i t is necessary to manually place the tone arm i n the record groove
while turntable is rotating, release i t as soon as the stylus engages the
record groove.
4. Correct improper set-down adjustment o r malfunction of the turntable
changing mechanism to prevent the stylus from striking the edge of the
turntable o r record. D o not stack more records than turntable rnanufac-
turer recommends.
5. Take care t o properly insert the stylus into the cartridge assembly and
the
cartridge
and shell assembly into the tone arm receptacle.
6. Use proper vertical tracklng force setting for each cartridge.
7. D o not use badly warped, cracked o r imperfect records.
8. When dusting the turntable protect the stylus with the stylus guard.
