CARTRIDGE REPLACEMENT

NOTE: Factory screw tightness is based on the thickness of the included 
slip mat. If a thinner or thicker 3rd-party slip mat is used, gently adjust the 
screw as needed following the steps in the last two situations.

5.   Connect the wire leads to the new cartridge’s terminals. The wire lead 
      color are as below:

6.   Adjust the cartridge’s position to make sure it is precisely aligned on 
      the headshell so that the stylus will be tracking the grooves in parallel 
      perfectly. To achieve this, place the included paper cartridge alignment 
      protractor over the turntable spindle, carefully lift the tone arm and 
      place the tip of the stylus on the points marked 130mm and 250mm 
      respectively. Fine tune the cartridge’s position on the headshell until
      the cartridge is perfectly in parallel with the reference lines at both  
      posits.
7.   Tighten the screws completely once the perfect alignment is achieved.

NOTE:
·     Design and specifications are subject to change without notice.

1.    Do not touch the stylus tip with your fingers. Avoid bumping the stylus 
      on the turntable mat or a record’s edge.
2.   Clean the stylus frequently with a soft brush with a back-to-front 
      motion only.
3.   Clean the records to get rid of dust or grease with a record cleaning 
      brush and record cleaning solution.
4.   Clean the turntable lid and turntable cabinet with a slightly damped 
      microfiber cloth.

NOTE: Do not use cleanser other that contains alcohol, benzene or any 
other harsh chemicals, with might damage the paint and finish of the
