mm
(1/4

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

TO PRESERVE STYLUS LIFE:
1.
Follow turntable or tone arm instructions when adjusting antiskating
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 or record. D o r ~ o t stack more records than turntable manufac-
turer 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.
D o not use badly warped, cracked o r imperfect records.
8. When dusting the turntable protect the stylus w i t h the stylus guard.
SPECIAL NOTE: To ma~ntain the o r ~ g i n a l performance standards of your
cartridge, be certain that any replacement stylus you buy bears the follow-
ing certification on the package: "This Stereo D y n e t ~ c O stylus is precision
