FOREWORD
The Nikonos Speedlight SB-103, an amphibious high'
oerformance electronic llash unit with a silicon'con'
trolled rectifier and series circuitry, is designed for use
with the Nikonos-V, Nikonos lV-A, and Nikonos lll. The
SB-103 can be submerged to a depth of 50 meters
(160 feet) and withstand pressure of up to 6kg/cm2
(85 lb/in'), enabling it to be used in environments where
regular speedlights could not be taken.
In combination with the Nikonos-V, the SB-103 features
automatic through-the-lens
(TTL) flash exposure control.
This means the silicon photodiode (SPD) in the Nikonos'
V's shutter box reads the light passing through the lens
and then automatically signals the speedlight to turn
itself off when the exposure is correct. Because TTL
flash offers a wide range of useable apertures and
shooting distances, depth of field is easy to control and
shooting as close as 0.3m (t tt) is possible. Daylight
fill-in flash photography becomes easier when using the
Nikonos-V.
To enable it to be used with the Nikonos lV-A and Nikonos
lll, the SB-103 features manual control with three power
s e t t i n g s : " M F U L L , " " M 1 | 4 , " a n d " M 1 / 1 6 . "
This speedlight has the same area of coverage as
a 28mm lens. When the Wide-Flash Adapter SW-103
(provided) is used, the area of coverage increaseg to
t h a t o f a 1 5 m m l e n s .
For multiple flash photography, a double flash bracket
and a double sync cord are available as options. In
addition, a variety of other optional accessories is avail-
able to increase the versatility of the SB-103.
Even though this speedlight is extremely easyto operate,
you should still familiarize yourself with the preparatory
steps and basic operations explained in the first two
sections of this manual. For more detailed information,

STOP! READ THIS NOTICE BEFORE USING YOUR SB.1O3. THE O.RING SEALS
MUST BE EXAMINED AND LUBRICATED
BEFORE USE TO AVOID DAMAGING
THE SPEEDLIGHT.
This Nikonos Speedlight SB-103 uses O-rings to seal
and waterproof the junctions between parts. Your
Nikonos Speedlight SB-103 should not be considered
waterproof until you have examined the O-rings (one
each for the battery chamber cap (0, the sync cord's @
camera and speedlight plugs, and the synchro socket
cover @ ). They must be in perf ect, undamaged condition
and properly lubricated prior to each use. Read the
following instructions thoroughly to familiarize yourself
with the maintenance of the O-rings.
Because the outer surface of your Nikonos Speedlight
SB-103 has been specially treated to make it waterproof ,
it must be protected f rom impact. lf it becomes damaged,
send it to a qualified technician for service before the
next use.
Your Nikonos Speedlight SB-103 is watertight only when
in perfectly serviced condition, when all O-ring seals
are in perfect condition, and when all components are
properly assembled and closed.
Pay special attention to the instructions for installing
the O-rings because they are what make the Nikonos
Speedlight SB-103 watertight. For the O-rings to perform
properly, they must be in perfect condition (with no cuts,
tears, or other imperfections) and properly lubricated.
lf they are not, they will not perform properly and may
allow water to enter your flash unit. To prevent the
4
accidental use of a defective O-ring, always discard
old O-rings.
The channels into which the O-rings fit must be free ol
any foreign matter and in their original, smoothly f inished
condition. lf they are not, the O-rings will not seat prop-
erly and may allow water to enter your flash unit. lf any
channel in your Nikonos Speedlight SB-103 becomes
damaged, send the unit to a qualified technician for
service before the next use.
All of the O-rings in your Nikonos Speedlight SB-103
must be examined at the end of each dive day and, if
oossible. after each dive.
