This

provides

you

with

a

Because

the

There

are

four

colored

wedges

(23)

with

trailing

range

lines

on

the

Calculator

Dial.

Each

color

represents

an

automatic

operating

mode

which

corresponds

to

an

automatic

f-stop.

Each

mode

takes

into

account

a

combination

of

two

things

—the

auto

range

and

depth

of

field

(greatest

sharpness

in

front

and

back

of

subject).

Which

colored

mode

you

select

will

depend

on

the

combination

you

want.

Select

the

will

give

you

the

-f

the

look

on

the

dial

and

find

the

colored

wedge

of

the

mode

and

the

range

line

that

trails

off

from

it.

It

looks

like

this:

The

number

at

the

end

of

the

line

is

the

closest

distance

from

your

subject

that

the

flash

can

be

properly

used.

The

number

in

the

center

of

the

wedge

is

the

longest

distance.

The

number

above

the

colored

wedge

is

the

f-stop

number

to

set

your

camera

lens

to.

If

the

colored

wedges

fall

between

two

different

f-stops,

refer

to

the

Automatic

Operation

Chart

at

rear

of

this

manual

in

order

to

determine

the

best

f-stop

to

use.

Example:

You're

using

ASA/ISO

100

(DIN

21)

film

with

the

Flash

Zoom

Head

in

the

NORM

position.

You

select

the

RED

mode.

Your

flash

range

would

be

5

to

30

feet

(1.5

to

9.t

meters)

and

the

f-stop

setting

would

be

f4.0.

position.

After

you

have

set

up

the

Calculator

position,

you

may

wish

to

operate

the

flash

unit

with

the

Zoom/Bounce

Head

in

the

WIDE

or

TELE

position.

When

the

Zoom/Bounce

Head

is

extended

or

retracted

from

the

NORM

position,

the

distance

scale

on

the

Calculator

Dial

will

change

position

automatically.

Example:

With

a

setting

of

ISO/ASA

100

(DIN

21),

when

the

Zoom/Bounce

Head

is

set

in

the

NORM

position,

the

operating

distance

'n

the

Red

mode

is

5-30

feet

(1

.5-9.1

m).

When

the

head

is

extended

to

TELE,

the

operating

range

for

the

Red

mode

becomes

6-35

feet

(1

.8-10.6

It

may

be

used

when

shooting

in

any

of

the

four

automatic

modes,

and

is

especially

helpful

in

one

of

the

following:

Set

your

flash

and

camera

to

an

automatic

mode

that

uses

a

wider

f-stop

opening;

or,

decrease

the

flash

-to

-subject

distance.

NOTE:

The

Sufficient

Light

Indicator

is

for

use

in

any

of

the

four

Automatic

Modes

and

will

not

light

if

the

or

if

the
