BATTERY

LIFE

When

a

new,

normal

battery

is

installed,

your

watch

will

operate

for

approximately

2.5

years.

*

If

the

alarm

is

used

more

than

once

a

day

and/or

if

the

stopwatch

or

timer

is

used

more

than

5

minutes

a

day,

the

battery

life

may

be

less

than

2.5

years.

*

As

the

battery

in

your

watch

is

a

monitor

battery

inserted

at

the

factory

to

check

the

function

and

performance

of

the

watch,

its

actual

life

once

in

your

possession

may

be

less

than

2.5

years.

*Battery

replacement

will

be

made

at

cost

even

within

the

guarantee

period.

CONSUMPTION

OF

BATTERY

POWER

•

Battery

power

is

consumed

even

though

the

hands

are_

not

moving.

An

extremely

small

amount

of

electricity

is

always

sup-

plied

to

the

electronic

circuit

in

order

to

make

the

watch

start

moving

immediately

and

correctly

after

it

is

stopped

and

the

battery

itself

discharges

electricity.

BATEERY

CHANGE

When

replacing

the

battery,

please

specify

the

"SEIKO

SB

Battery"

at

the

retailer

from

whom

your

watch

was

purchased

or

at

an

authorized

SEIKO

DEALER.

We

suggest

that

the

battery

should

be

replaced

as

soon

as

possible

when

you

see

the the

second

hand

moving

in

two

second

intervals.

If

an

old

battery

is

kept

in

the

watch

for

a

long

time,

electrolyte

leakage

from

the

battery

may

damage

the

module.

*

When

a

battery

is

taken

out

of

a

watch,

it

must

be

kept

at

a

place

beyond

the

reach

of

an

infant.

In

case

it

is

swallowed

by

an

infant,

consult

a

doctor

immediately.
