Please note
To avoid damages on the stylus please keep the stylus guard on the cartridge any time when mounting or dismounting the unit.

Mounting the cartridge

1. Remove stylus unit with stylus guard before working with leads and screws. Handle all parts carefully.
2. Please correlate the colour code for the terminals on the drawing with the colour codings on the cartridge.
3. Fasten the cartridge to the headshell using a pair of screws enclosed the packing. Do not tighten the screws completely before the stylus unit has been remounted.
4. Adjust tonearm parallel to record surface, set tracking force and antiskating acc. to the cartridge’s recommended technical data.

Stylus care

To maintain optimal sound reproduction and to minimize wear on your record as well as on your stylus, we recommend the following procedure before and after each playback: remove dust carefully from record surfaces by using a fi ne antistatic brush or cloth before every use. Ortofon do not recommend the use of solvents of any kind for cleaning of either record surface or stylus. If necessary, records may be washed in lukewarm demineralized water with a dash of sulphonic soap. The detergents should be allergy- & environmental friendly, without perfume or as little as possible: a few drops to a few liters of waters, no lather.

The use of solvents on the stylus and cantilever may damage stylus cement; interior parts of the cartridge can be affected seriously by the intrusion of solvents. The Ortofon warranty service will not be valid in cases where such treatment has caused malfunction of your cartridge.

For cleaning the stylus, use fi ber brush a few times along the cantilever in the direction of the stylus tip, whenever you play a new record or change sides. Use the brush in the forward direction from the rear of the cartridge towards the stylus tip and never from stylus tip to the rear of the cartridge and never from side to side. This will take all normal dust and most of the slick release agent from new records. Following this treatment there will normally be no need for further stylus cleaning.

Please remember to remove dust from the diamond tip before and after playback of each record.
