REMEMBER: YOU ARE ALIGNING THE CARTRIDGE NOT THE

HEADSHELL



Double check the adjustments made above. The cartridge needs to be

both centered and "square" between the gird lines and have the stylus

resting on the dot or very close to it.



The alignment gauge does not have a hole or dimple to hold the stylus.

While the printed dot makes it harder to keep the stylus in place, this

method was chosen to avoid the possibility of damaging the stylus

cantilever or the diamond tip as the cartridge is positioned.



Place the arm back in its rest.



Without letting the cartridge move, tighten the screws holding the

cartridge to the arm head. Do not over do it as you will damage the

JMW-3D arm headshell.

D- TRACKING FORCE (VTF):



Tracking force is adjusted by moving the counterweight forward and back

just a bit at a time. A little light oil on the counterweight shaft will let you

move the counterweight easier and you can wipe it up when done.



The JMW-3D tonearm does not have a built-in tracking force gauge, but a

Stylus Force Gauge is supplied with your complete arm on a new unit.



A stylus force gauge does not come with the purchase of just an

armtube
