FOREWORD

The Nikonos 8peedlight 88-102
,
an amphibious
high-
performance electronic flash unit with a sil
icon-con-
trolled rectifier and series
circuitry,
is designed for use
with the
Nikonos-V,
Nikonos
IV-A,
and Nikonos III. The
88-102 can be submerged to a depth of 50 meters
(160 feet) and withstand pressure of up to 6kg/cm
2
(85 Ib/in
2 )
,
enabling it to be used in environments where
regular speedl ights could not be taken
.
In combination with the
Nikonos-V,
the 88-102 features
automatic through-the -Iens (TTL) flash exposure con-
trol. This means the silicon photodiode (8PD) 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. 8ecause
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 (1 tt) is possible
.
With the optional 8ensor Unit 8U-101
,
the 88-102 can
be used for non-TTL automatic flash photography in
combination with the Nikonos -V, Nikonos
IV-A,
and
Nikonos III. In this mode, flash output is automatically
controlled by the 8 U-101
.
This speed light has the same area of coverage as a
28mm
lens.
When the Wide-Flash Adapter 8W-102
(provided) is
used,
the area of coverage increases to
that of a 15mm
lens.
The 88 -102 also features manual control with three
power settings
("FULL," " M1/4,"
and "
M1/16" ),
slave
firing capability for wireless multiple flash
photography,
and a target-light for close -up
shooting.
The
target-light,
pOSitioned in the center of the flash
head,
shoots a
beam of light at the subject to help you aim the flash
head at the subject. In addition to the equipment men-
tioned
,
a variety of optional accessories is available to
increase the versatility of the 88 -102.
Even though this speedlight is extremely easy to oper-
ate, you should still familiarize yourself with the pre-
paratory steps and basic operations explained in the
first two sections of this manual. For more detailed
information, refer to
"CONTROLS IN
DETAIL"
and
"TIPS ON FLASH
PHOTOGRAPHY."
A few
minutes
wisely invested now will payoff later in
years
of
reward-
ing photographic
experiences.
PREPARATION
_ _ _ _ _ _ _ _ _
STOP! READ THIS NOTICE BEFORE USING YOUR
SB·102.
THE O·RING SEALS
MUST BE EXAMINED AND LUBRICATED BEFORE USE TO AVOID DAMAGING
THE SPEEDLIGHT.
This Nikonos 8peedlight 88-102 uses O-rings to seal
and waterproof the junctions between
parts.
Your
Nikonos 8peedlight 88-102 should not be considered
waterproof until you have examined the user-service-
able O-rings (one each for the battery chamber cap
@
,
the sync cord's
@
camera and speedlight plugs
,
and
the synchro socket and sensor socket covers
®
@).
They must be in perfect, undamaged condition and
properly lubricated prior to each
use.
Read the follow-
ing instructions thoroughly to familiarize yourself with
the maintenance of the
O-rings.
8ecause the outer surface of your Nikonos 8peedlight
88-102 has been specially treated to make it water-
proof,
it must be protected from impact. If it becomes
damaged, send it to a qualified technician for service
before the next use.
Your Nikonos 8peedlight 88-102 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-ri ngs because they are what make the Nikonos
8peedlight 88-102 watertight. For the O-rings to per-
fo rm properly, they must be in perfect condition (with
no cuts, tears,
or
other imperfections) and properly
lubricated.
If they are
not,
they will not perform properly
and may allow water to enter your flash unit. To prevent
4
the accidental use of a defective O-ring
,
always discard
old rings
.
The channels into which the O-rings fit must be free of
any foreign matter and in their original
,
smoothly finished
condition. If they are
not,
the O-rings will not seat pro-
perly and may allow water to enter your flash unit. If any
channel in your Nikonos 8peedlight 88 -102 becomes
damaged, send the unit to a qualified technician for
service before the next
use.
Your Nikonos 8peedlight 88-102 contains a
series
of
O-rings.
80me are factory-installed and cannot be
serviced by you
.
Once each year, send your flash unit
to a qualified technician so that these O-rings can be
serviced. Do not attempt to disassemble the unit and
service these O-rings yourself.
All of the O-rings in your
Nikonos
8peedlight S8-102
that can be serviced by you must be examined at the
end of each dive day and, if possible
,
after each dive.
