- Stylus Guard: Ensure the stylus guard is in place during mounting to protect the diamond tip.
- Alignment (Crucial): Proper cartridge alignment is critical for optimal sound quality and to prevent record wear. Refer to your turntable's manual for specific alignment instructions, which typically involve adjusting overhang and azimuth. Tools like an alignment protractor may be necessary.
- Tracking Force: Set the tracking force on your tonearm to 3.0 grams. The acceptable range is 2.5 to 3.5 grams. Use a stylus force gauge for accurate measurement.
- Anti-Skate: Adjust the anti-skate setting on your tonearm according to your turntable's manual, typically matching the tracking force value.
