REMOVING & REPLACING THE DETENT DISC
Once the Indexing Hub is removed, the detent disc can be removed from its re- cess in the bottom of the Vertical Bracket. The disc may slip out once the Index- ing Hub is removed. If it sticks inside the recess, simply insert the tip of a ballpoint pen or a pin small enough to fit into the detent disc ejection hole on the top of the bracket and push the detent disc out of the detent disc recess.
With the disc removed, a different disc can be inserted to change the angular spacing. The 14 position detent disc (included with your bracket) is for use with the optional Nikon wide angle lens (available from Nikon for the Coolpix 900/950).
To install a different disc, simply align the keyed slot and push the disc into the recess. Make sure the disc is properly seated and flush to the bottom surface of the Vertical Bracket. With the new disc inserted, reassemble by inserting the In- dexing Hub back through the bearing in the Vertical Bracket.
REPLACING THE FRICTION CAP
Replace the Friction Cap by threading the Cap back onto the axle. Continue to thread the cap so that there is no free play between the Vertical Bracket and the Indexing Hub. The rubber washer on the bottom of the Friction Cap should be slightly compressed. When the drag feels adequate, turn the Friction Cap so that the threaded shaft of the Retaining Knob is aligned with the closest flat on the axle. Tighten the Retaining Knob to lock the Cap in place.
