Color

Color

video

is

composed

of

red,

green

and

blue

images.

When

the

VPM500

is

cor-

rectly

adjusted,

these

three

images

are

projected

precisely

on

top

of

one

another,

and

show

only

a

very

slight

separation

(if

any)

at

the

extreme

sides

of

the

screen.

If

the

three

images

are

out

of

convergence,

you

will

see

color

outlines

around

objects.

This

is

especial

ly

noticeable

on

black

and

white

movies

and

TV

reruns.

While

the

VPM500

has

been

engineered

with

the

finest

quality

video

circuitry,

there

will

be

times

when

you

will

need

to

readjust

the

convergence

of

the

three

pro-

jection

tubes.

You

will

also

definitely

need

to

converge

the

VPM500

image

the

first

time

you

operate

it.

This

is

a

simple

operation

which

takes

just

seconds

and

can

be

done

from

the

comfort

of

your

armchair

(although

the

controls

are

dupli-

cated

on

the

control

console).

A.

First

familiarize

yourself

with

the

loca-

tion

of

the

following

controls:

1.

TEST

button

2.

RED

H,

RED

V

3.

BLUE

H,

BLUE

V

B.

Press

the

TEST

button.

Cross

lines

will

appear

on

the

center

of

the

screen.

To

get

a

feeling

for

the

adjustment

process,

press

the

RED

H

button

on

its

—

side.

Note

how

the

red

cross

line

moves

to

the

left

and

the

surrounding

picture

has

red

outlines.

C.

Simply

use

the

RED

H,

RED

V,

BLUE

H

and

BLUE

V

controls

to

produce

a

single

white

cross

line.

The

blue

cross

line

is

the

hardest

to

see

clearly.

If

you

have

trouble,

further

reduce

room

light

level

or

reduce

the

COLOR

picture

control

to

its

minimum

to

produce

a

black

and

white

picture.

D.

Press

the

"SET

PRESET"

button

on

the

rear

panel

of

the

VPM500,

behind

the

door

near

the

power

switch.

E.

Then

press

TEST

again

to

make

the

cross

line

diappear.

Why

isn't

there

a

green

control?

The

green

projector

cross

line

is

the

standard

to

which

you

adjust

the

other

two

colors.

So

it

can

be

stationary.

First

move

the

red

cross

lines

to

cover

the

stationary

green

lines.

This

will

produce

a

dark

shade

of

yellow.

Now

move

the

blue

lines

over

the

yellow,

resulting

in

white.

What

if

you

can't

get

a

pure

white

cross

hair?

The

first

suspect

is

the

placement

of

screen

and

projector.

Make

sure

the

VPM500

is

prop-

erly

centered

and

that

the screen

is

cor-

rectly

placed.

The

next

possibility

is

the

quality

of

the

video

input

source.

If

you

are

using

broad-

cast

television

for

a

test

source,

try

a

high

quality

videocassette

to

see

if

the

problem

still

persists.

If

it

doesn't,

your

tuner

may

be

the

culprit.

In

the

rare

event

that

neither

of

these

factors

is

at

fault,

internal

adjustments

may

need

to

be

made

in

the

VPM500.

Consult

your

Harman

Kardon

dealer

or

qualified

installer.

Remote

mania.

It

is

possible

to

have

separate

remote

controls

for

the

VPM500,

your

VCR/tuner

and

stereo

system

all

clustered

around

your

viewing

area.

If

this

gets

un-

wieldy,

we

suggest

you

investigate

a

new

product

development,

the

"universal"

remote.

Produced

by

several

companies,

it

lets

you

program

the

functions

of

multiple

remotes

into

a

single

compact

unit.

We

hope

you

have

many

years

of

rewarding

viewing

experiences

from

your

Harman

Kardon

VPM500.

The

same

innovation

and

quality

is

found

in

a

whole

range

of

other

Harman

Kardon

video

and

audio

products

and

JBL

loudspeakers.

Think

of

us

when

you

want

to

further

upgrade

your

Home

Theater.

And

in

the

meantime.

. .

ENJOY!
