SECRET

CODE

This

unit

is

equipped

with

a

secret

code

function.

The

secret

code

(4-digit)

electronically

locks

the

unit

to

reduce

the

danger

of

theft.

The

code

is

preset

to

[! [}

J

[fat

the

time

of

purchase,

and

the

unit

can

be

used

normally

without

altering

the

code

as

preset.

It

is

recom-

mended,

however,

that

the

user

change

the

code

to

another

value

to

take

full

advantage

of

the

anti-theft

properties

of

this

system.

Once

a

code

is

set,

the

unit

will

operate

normally

without

input

of

the

secret

code,

even

if

the

ignition

of

the

vehicle

is

switched

OFF

and

then

ON

again.

Should

power

to

the

unit

be

interrupted

due

to

a

battery

change,

repairs,

or

theft,

however,

the

unit

will

fail

to

operate

when

power

is

restored

unless

the

preset

secret

code

is

first

entered.

Three

consecutive

wrang

inputs

of

the

code

will

cause

the

unit

to

lock

electronically

to

accept

no

input

of

code

for

three

hours.

Once

operation

is

restored,

three

more

wrong

code

inputs

result

in

another

three

hours

of

electronic

lock

up.

This

feature

helps

to

prevent

breaking

of

the

secret

code

through

sequen-

tial

or

random

input.

These

features

mean

that

once

the

power

supplied

to

the

unit

is

com-

pletely

cut,

further

operation

is

impossible

except

for

those

who

know

the

secret

code.

This

makes

the

unit

unuseabie

if

stoien,

thus

reducing

the

danger

of

theft.

.

¢

When

taking

the

unit

to

a

service

station

for

repair,

be

sure

to

either

tell

the

service

personnel

the

registered

code

or

the

value

Should

you
