COMPASS

CALIBRATION

The digital

compass

in CXR-I is

calibrated

from

the factory and does not

require, under normal

circumstances,

any

further

maintenanc

e.

In

certain instances,

ho

w

e

v

er

,

such as

aft

er

exposure

to

e

xtr

emel

y

intense magnetic

fields,

it may be

necessary

to

recalibrate

the

c

ompas

s

to

ensure

its

accuracy.

If you notice an

obvious

deviation in the indication of the

c

ompas

s,

access

this

menu

and

perform

the

calibration

as

described bel

o

w

.

First

you

must enter

the

security

Then the image shown in Figure 7

appears on

the

.

Now hold CXR-I

horizontal

to the

almost

any

inclination.

The

compass

can be called up at any

moment

SETTING

A BEARING

With you can set a

reference bearing. This

is

useful

for

instance

if you are on a boat

and

there

is a

landmark

on the

shore

that you

c

an

use for

alignment

to

reach

a specific spot

on

that dive site.

Press

and a dot will

appear

to

indicate

the set

bearing.

Additional

symbols

will

appear

as well:

squares

at 90

degr

ees,

triangles

at 120

degrees

and two

par

allel

lines at 180

degrees,

as an aid in

navigation

for square, triangular

and

reciprocal

c

our

ses.

The

number

at the bottom

represents the

deviation of the

direction

you are pointing

at

with

reference

to the set

bearing.

Once

underwater,

align the dot with the

arr

o

w

and

start swimming

in that

direction.

If

y

ou

press

again, the new

bearing

will

o

v

erride

the one in

memory.

If you

press

and

hold

you

erase

the

bearing.

3.2. UNITS

Y

ou

can

choose between metric

(depth

in

meters, temperature

in °C, tank

pressure in

bar) and

imperial

(depth in feet,

t

emperatur

e

in °F, tank

pressure

in

psi).

3.3. CLOCK

This

menu

allows you to set the time

f

ormat,

time, date, time zone shift and

wake-up

alarm.

3.4. BRIGHTNESS

COMPASS

DECLINATION

Depending

on the exact location on the

planet,

there

can be a deviation

between

true

North

and

magnetic

North.

Any

compass

will

al

ways

show

magnetic

North, so via this

menu

you

c

an

set a value for the

so-called declination

that will

make the

compass

show true North
