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

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

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's axis 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-
attached
to
the
bracket

in
the sensor holder; then screw the knob clockwise
until
it
