13. Securing Cartridge The screws holding to the headshell must now be tightened and it is very important to avoid moving the position of the cartridge, so tighten in the following way: slowly, one screw at a time in extremely small stages. Before screws are completely tight check that cartridge is still in alignment at position B and then at position A.Then tighten screws firmly bearing in mind whether the cartridge body is made of metal or plastic!
NOTE: If you find it impossible to align the cartridge, ie. the cartridge cannot move far enough forward in the slots of the headshell, then the tonearm is incorrectly positioned on the armboard, being too far from the record centre. If the cartridge cannot be moved far enough back in the headshell, then the arm is too near the centre of the record. In either case the tonearm will have to be repositioned on the armboard. It should be noted however, that different cartridges allow for more or less movement than others.
