EASY TO INSTALL: Remember the tabs on the stylus body and the slots on the bottom of the cartridge before installing. Be careful not to touch the pins. Holding the stylus by its side, insert the tab on the stylus into the slot on the bottom of the cartridge and turn the stylus body upward, making sure there is no gap between the top of the stylus and the head of the case.
