while turntable is rotating, release it as soon as Lhe stylus engages the
record groove.
4. Correct Improper set-down adluslment or malfunction of the turntable
changing rneclianism to prevent the stylus from ~trikingthe edge of the
turntable or record. Do not stack more records than turntable manufac-
turer recommends.
