Thank

you

for

purchasing

this

Canon

product.

The

Canon

Speedlite

540EZ

is

a

high-performance

flash

unit

designed

for

use

with

EOS

Series

cameras.

The

540EZ

incorporates

a

rich

selec¬

tion

of

based

on

user-selected

shutter

speed

and/or

aperture

settings,

manual

Metering

for

Multi-Point

Autofocus

Systems

When

the

540EZ

is

used

with

an

EOS

camera

that

has

multiple

focusing

points,

the

flash

automatically

weights

the

in

the

area

of

the

active

focusing

point

using

the

camera’s

three-zone

flash

metering

system.

(4)

flash

unit

lights

for

two

seconds

to

indicate

that

proper

flash

exposure

was

achieved.

(5)

The

flash

head

automatically

zooms

to

set

the

head

can

be

tilted

upward

or

can

be

surveled

to

the

right

or

left

for

bouncing

flash

off

of

nearby

surfaces

such

as

a

ceiling

or

wall

to

create

a

repair.

(2)

The

540EZ

is

not

resistant

to

water

and

should

not

be

used

outdoors

in

snow

or

rain.

If

momentarily

exposed

to

snow,

rain

or

water

spray,

immediately

wipe

water

drops

from

the

flash

unit’s

surface

with

a

dry

cloth.

(3)

Always

slide

the

540EZ’s

power

switch

to

the

OFF

position

after

use.

If

left

on,

the

flash

circuitry

will

drain

the

battery

power.

(4)

Be

sure

to

keep

the

out

of

direct

sunlight,

and

away

from

“hot

spots”

such

as

the

trunk

or

rear

win¬

dow

shelf

of

a

car.

Extended

expo¬

sure

to

high

temperatures

can

cause

the

flash

unit

to

malfunction.

Preparations

for

Use

1.

Loading

the

Batteries

The

540EZ

uses

four

AA-size

batteries.

Use

either

of

the

following

battery

types:

(1)

Four

AA-size

alkaline-manganese

batteries

(LR6/AM-3)

(2)

Four

AA-size

Ni-Cd

batteries

(KR15/51)

“j

Open

the

battery

cover

by

sliding

it

downward

slightly

and

then

swinging

it

outward.

2

Load

the

batteries

with

their

+

and

-

ends

oriented

as

shown

in

the

diagram

inside

the

bat¬

tery

chamber.

3

Close

the

battery

cover.

Battery

Notes

•

Use

four

new

batteries

of

the

same

type,

and

always

replace

all

four

batteries

at

the

same

time.

•

AA-size

manganese

batteries

(R6/UM-3)

can

also

be

used,

but

will

provide

fewer

flashes

than

alkaline-manganese

or

Ni-Cd

batteries.

•

The

terminals

of

some

AA-size

Ni-Cd

batteries

are

of

different

shape

than

stan¬

dard

AA-size

batteries.

Make

sure

the

batteries

are

usable

before

purchasing.

•

When

you

will

not

use

the

flash

for

a

long

period

of

time,

be

sure

to

remove

the

batteries

and

store

them

separately.

•

In

cold

environments,

prepare

two

sets

of

fully-charged

Ni-Cd

batteries

and

keep

one

set

in

a

warm

location

such

as

an

inside

pocket.

When

the

set

in

the

flash

becomes

weak,

exchange

it

with

the

warm

set.

The

weak

set

can

be

used

again

later

after

it

returns

to

a

warmer

temperature.

•

Dirty

battery

contacts

can

prevent

the

flow

of

electrical

power

to

the

flash

circuit¬

ry.

To

prevent

corrosion

and

dirt

built-up,

wipe

the

contacts

with

a

clean

cloth

each

time

you

exchange

the

batteries.

•

AA-size

lithium

batteries

(FR6)

can

also

be

used

in

the

540EZ.

Recycle

Time

Short

recycle

times

are

invaluable

in

fast-changing

situations

where

quick

shooting

is

necessary.

For

this

purpose,

the

540EZ

provides

a

quick

firing

mode

in

addition

to

its

normal,

full-power

firing

mode.

In

quick

firing

mode,

the

flash

can

be

fired

before

it

is

fully

charged

to

provide

fast

recy¬

cle

times.

You

can

tell

whether

the

flash

is

operating

in

normal

firing

mode

or

quick

firing

mode

by

the

color

of

the

ready

lamp,

as

described

below.

•

What

is

a

guide

number?

The

guide

number

of

a

flash

unit

is

a

numerical

indicator

of

its

light

output

capaci¬

ty.

The

appropriate

shooting

distance

or

lens

aperture

required

for

proper

flash

exposure

can

be

calculated

from

the

guide

number

using

the

following

formulas:

Guide

number

-f

shooting

distance

(m)

=

proper

aperture

value

Max.

shooting

•

The

film

speed

is

usually

assumed

to

be

ISO

when

stating

guide

numbers.

At

different

film

speeds,

the

guide

number

increases

or

decreases

accordingly.
