HOW

TO

USE

First,

adjust

the

width

(interpupillary

distance)

of

your

binoculars

so

that

when

you

look

through

them,

you

see

a

single

circular

image

Then

focus

the

binocular

for

one

eye

at

a

time

by

turning

the

ocular

(eyepiece)

until

you

see

an

equally

sharp

image

with

each

eye

If

more

than

one

person

will

be

using

the

binoculars.

you

should

mark

the

left

and

right

eyepieces

for

your

own

vision

to

permit

quick

readjustment

USING

THE

COMPASS

The

compass

is

a

precision

unit

It

has

extremely

fast

damping

so

that

there

is

almost

no

'swing'

and

is

connected

for

dip

(Latitude)

The

compass

scale

is

in

one

degree

increments

and

is

aligned

with

the

vertical

range

finding

scale.

When

using

the

compass,

always

keep

in

mind

the

local

variation

between

magnetic

and

true

north

die

HOW

TO

USE

THE

RETICLE

The

vertical

scale

(reticle)

visible

through

the

left

half

of

the

binocular,

above

the

compass

display,

allows

you

to

calculate

distance

to

an

object

if

you

know

its

height,

or

to

calculate

the

height

of

an

object

if

youknow

its

distance

from

you

Each

mark

on

the

vertical

scale

has

a

value

of

5

MIL

(1

Mil

is

equivalent

to

an

angle

that

can

determine

an

object

one

meter

in

height

at

a

distance

of

1000

meters)

Therefore,

if

a

navigation

chart

gives

the

height

of

an

object,

by

sighting

on

it

and

counting

the

number

of

MILs,

you

can

determine

how

far

away

it is
