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

while turntable is rotating, release it as soon as the stylus ensaaes the
- -
record groove.
4. Correct improper set-down adjustment or malfunction of the turntable
changing mechanism to prevent the stylus from striking the edse of the
turntable or record. Do 'not stack more records than t6rntablemanufac-
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.
