NET WEIGHT: 6.2 grdnls
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 ohms with almost no audible change in frequency response. Total capaci- tance includes both tone arm wiring and amplifier input circuit.
FOUR-CHANNEL: This Stereo Dynetic@ cartridge is compatible with all four-channel matrix systems.
MONOPHONIC OPERATION: Set function switch on amplifier to "MONO" or "A+B." If amplliier is not equipped with this switch, connect left and right channels in parallel.

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 operat~onsrrlce this may cause the arm to sweep across the record.
3.I f it is necessary to manually place the tone arm in the record groove while turntable is rotating, release it 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 or record. Do not 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 asscmbly into the tone arm receptacle.
6.Use proper vertical tracking force setting for each cartridge.
7.Do not use badly warped, cracked or imperfect records.
8.When dusting the turntable protect the stylus with the stylus guard.
