NET WEIGHT: 5.7 grams

INDUCTANCE: 720 millihenries

DC RESISTANCE: 630 ohms

OPTIMUM LOAD: 47,000 ohms resistance in parallel with 400 to 500 pico- farads total capacitance per channel. Load resistance can be up to 70,000 ohrns with almost n o audible change i n frequency response. Total capaci- tance includes both tone arm wiring and amplifier input circuit.

RECOMMENDED STYLUS CLEANING: Use a camel's hair brush (No. 2 slze o r smaller), trlmrncd to

approximately

6 mm (1/4 in.), dipped i n alcohol or an alcohol-distilled water solution.

Commercial

cleaning solutions may cdusf stylus darnage or corrosion. Always brush stylus irom back to front; never brush o r wipe stylus from front to back or side to side.

TO PRESERVE STYLUS LIFE:

1 . Follow turntable o r tone arm instructions when adjusling antiskating force.

2 . D o n o t handle [he tone arm while i t is i n operation since this may cause the arm to sweep across the record.

3 If ~t is necessary to manually place the tone arm i n the record groove while turntable is rotating, release 11 as soon as the stylus engages the record groove.

4. Correct improper set-down adjustment or 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 manufac- 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 tracking force setting for each cartridge.

7. D o not use badly warped, cracked or imperfect records.

8. When dusting the turntable protect the stylus with the stylus guard.

SPECIAL NOTE: To maintain the original performance standards of your cartridge, be certain that any replacement stylus you buy bears the follow-

Ing certification o n the package: "This Stereo Dynetic@ stylus is precision manufactured by Shure Brothers Inc." AVOID INFERIOR IMITATIONS. THEY
