FOREWORD

_ _ _ _ _ _ _ _ _

The Nikonos 8peedlight 88-103, an amphibious high

performance electronic flash unit with a silicon-con-

trolled rectifier and series circuitry, is designed for use

with the

Nikonos-V, Nikonos

IV-A,

and Nikonos III. The

88-103 can be submerged to a

depth

of 50 meters

(160 feet) and withstand pressure of up to 6kg/cm2

(85Ib/in

2 ),

enabling it to be used in environments where

regular speedlights could not be taken

In combination with the

Nikonos

-V, the

-103 features

automatic through-the-Iens (TTL) flash exposure control.

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 ft) is

possible.

Daylight

fill-in flash photography becomes easier when using the

Nikonos-V.

To enable itto be used with the Nikonos IV-A and Nikonos

III

the 88-103 features manual control with three power

settings

"MFULL,"

M1/4

and

"M1/16."

This speedlight has the same area of coverage as

a 28mm

lens.

When the Wide-Flash Adapter 8W-103

(provided)

is used, the area of coverage increases to

that of a 15mm

lens.

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

88-103.

Even though this speedlight is extremely easy to 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,

refer to

CONTROL8 IN

DETAIL"

and

TIP8 ON 8PEED-

LIGHT

PHOTOGRAPHY."

A few minutes wisely invested

now will payoff later in years

rewarding photographic

experiences.

PREPARATION

_ _ _ _ _ _ _ _ _

STOP! READ THIS NOTICE BEFORE USING YOUR SB·103. THE O·RING SEALS

MUST BE EXAMINED AND LUBRICATED BEFORE USE TO AVOID DAMAGING

THE SPEEDLIGHT.

This Nikonos 8peedlight 88-103 uses O-rings to seal

and waterproof the junctions between

parts.

Your

Nikonos 8peedlight

88-103

should not be considered

waterproof until you have examined the O-rings (one

each for the battery chamber cap @, the sync cord's

camera and speedlight plugs

and the synchro socket

cover

® ).

They must be in

perfect,

undamaged condition

and properly lubricated prior to each

use.

Read the

following instructions thoroughly to familiarize yourself

with the maintenance of the O-rings.

8ecause the outer surface of your Nikonos 8peedlight

88-103 has been specially treated to make it

waterproof,

it must be protected from

impact.

If it becomes damaged,

send it to a qualified technician for service before the

use.

Your Nikonos 8peedlight 88-103 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

8peedlight 88-103 watertight. For the O-rings to perform

properly,

they must be in perfect condition (with no

cuts,

tears,

or other imperfections) and properly lubricated.

If they are not, they will not perform properly and may

allow water to enter your flash unit. To prevent the

accidental use of a defective

O-ring,

always discard

old

O-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 prop-

erly and may allow water to enter your flash unit. If any

channel in your Nikonos 8peedlight 88-103 becomes

damaged, send the unit to a qualified technician for

service before the next

use.

All of the O-rings in your Nikonos 8peedlight 88-103

must be examined at the end of each dive day and

possible

after each

dive.
