3.3. Setting Tracking Force

The recommended tracking force for the Ortofon 2M Red is 1.8 grams (18 mN). Refer to your turntable's manual for instructions on balancing the tonearm and setting the tracking force accurately. Incorrect tracking force can lead to poor sound quality and accelerated stylus wear.

3.4. Setting Anti-Skating

Set the anti-skating force to match the tracking force (1.8 grams). This helps prevent the tonearm from being pulled towards the center or outside of the record, ensuring even wear on the stylus and balanced channel output.

2. Place a clean record on the platter.
3. Gently lower the tonearm onto the record's lead-in groove using the cueing lever. Avoid dropping the tonearm directly onto the record.
4. After playback, use the cueing lever to lift the tonearm and return it to its rest. Always engage the stylus guard when the turntable is not in use.

5. การบำรุงรักษา

Regular maintenance ensures the longevity and performance of your cartridge.

5.2. การเปลี่ยนสไตลัส

The stylus is a consumable part and will wear out over time, typically after 500-1000 hours of playback, depending on record condition and cleaning habits. A worn stylus can damage your records and degrade sound quality. The 2M Red stylus is user-replaceable. Replacement styli (e.g., Ortofon Stylus 2M Red or an upgrade like Stylus 2M Blue) can be purchased separately. To replace, gently pull the old stylus assembly forward and off the cartridge body, then carefully push the new stylus assembly onto the body until it clicks into place.

5.3. Cartridge Body Cleaning

Wipe the cartridge body with a soft, dry, lint-free cloth. Avoid using cleaning fluids on the cartridge body or stylus, unless specifically designed for phono cartridges.
