Bracket ®

As indicated in the diagram there are two positions for the bracket screw @: one for Nikonos-V and Nikonos IV-A and another for the Nikonos III. To reposition the bracket screw, unscrew it, then screw it back into the hole or the threaded end of the bracket slot @ . Once screwed into the bracket slot, the bracket screw can be moved to any position.

The larger hole in the center allows the sync cord to be connected through the bracket to the Nikonos III.

The small hole that goes completely through the bracket is the sensor holder socket @ . When a plastic frame finder or optical underwater viewfinder is mounted on the camera 's accessory shoe, the optional sensor holder is used to attach the Sensor Unit SU-101 to the speedlight bracket. To attach , align the sensor holder positioning pin @ on the top of the bracket with the hole

Arm @

To attach the arm to the joint © , insert the arm position- ing screw @ into the slot in the jOint from either side. Align the arm positioning screw with the arm positioning index @ on the joint by turning the arm 90°. After align- ing the arm positioning screw with the arm positioning index, turn the joint lever @ clockwise as far as it will go to lock the arm into position . When the arm is attached in this manner, the speed light'saxis will always inter- sect with the lens's optical axis, even if the flash head is moved up or down on the arm . (Normally, the joint is locked at the top of the arm.) Before diving, be sure the jOint knob @ and jOint lever are locked tightly.

To attach the arm to the bracket, turn the arm knob @ counterclockwise as far as it will go to loosen it (the two bracket pOSitioning pins on the bottom of the grip @ will be visible). Slide the open end of the bracket between the arm knob and the grip, seat the two bracket posi-

in the sensor holder ; then screw the knob clockwise until it is tight.

The small hole on the underside of the bracket is the tripod socket @l .

•When the bracket and arm are attached to the Nikonos IVA certain optical finder models for older UW-Nikkor 15mm f12.8 lenses cannot be attached. If this presents a problem for you, authorized Nikon dealers and service centers can perform the necessary modification.

tioning pins in the two indentations on the bracket, and turn the arm knob clockwise as far as it will go to lock the bracket into position. The correct arm/bracket posi- tion is with the two washers on the underside of the bracket, the rubber side of the bracket facing up, and the flat side of the grip perpendicular to the bracket.
