Setup and Installation

Proper installation of the cartridge and stylus is crucial for sound quality and to prevent damage. This section outlines the steps for replacing or installing the stylus and cartridge.

Stylus Replacement

1. Remove the old stylus: Gently locate the small notch on the front of the existing stylus. Carefully pull the stylus downwards and away from the cartridge body to detach it.
2. Prepare the new stylus: Unpack the new stylus. Ensure it is clean and free from debris.
3. Install the new stylus: Align the new stylus with the cartridge body, following the groove line. Gently push the stylus upwards and inwards until it clicks securely into place. Ensure the top of the stylus is flush with the cartridge body.

Cartridge Installation (if replacing the entire cartridge)

If you are replacing the entire cartridge, ensure your turntable's tonearm is properly balanced and aligned after installation. The cartridge comes with a fixing bolt for secure attachment to the headshell.

Operating Instructions

Once the cartridge and stylus are correctly installed, operate your turntable as usual. Ensure the tonearm's tracking force is set within the recommended range of 1.0-1.5 grams for optimal sound reproduction and to minimize record wear. Refer to your turntable's specific manual for instructions on adjusting tracking force and anti-skate settings.

Maintenance

Regular maintenance helps preserve the life of your stylus and maintain sound quality.

• Stylus Cleaning: Use a soft brush, specifically designed for stylus cleaning, to gently brush the stylus tip from back to front. Never brush from front to back, as this can damage the cantilever. Clean the stylus regularly to remove dust and debris that can accumulate during playback.
• Stylus Guard: Always use the provided stylus guard when the turntable is not in use or during transport to protect the delicate stylus tip from accidental damage.
• Storage: When not installed, store the cartridge and stylus in a clean, dry place, away from direct sunlight and extreme temperatures.
