SPECIAL NOTE
As the only source of contact between the record groove and the balance of your
high fidelity system, the stylus in your cartridge plays a crltlcal role in the ultimate
quality of sound reproduction. Additionally, because records can be irreparably
damaged by a worn stylus, it is essential to ensure that your Shure stylus is in peak
condition in order t o preserve your records in "mlnt" condition. Your cartr~dgecan
perform at original operating specifications for many years with these simple
maintenance steps:
1. Follow the stylus cleaning instructions given on page 4
2. See your Shure dealer at least once a year for a checkup of your cartridge's
stylus. He'll clean it and inspect i t for wear.
3. When it becomes necessary t o replace your stylus, insist on a genulne Shure
replacement Extensive testing of imitations of Shure styli revealed numerous
grave flaws To be c e r t a ~ nthat your replacement stylus meets orlglnal
specifications, look for the name SHURE@on the stylus grip and the words
"This Stereo DYNETIC@stylus is precision manufactured by Shure Brothers
Inc." on the stvlus box.
