Handling

Precautions

•Your

calculator

is

made

up

of

precision

components.

Never

try

to

take

it

apart.

*Avoid

dropping

your

calculator

and

subjecting

it

to

strong

impact.

•

Do

not

store

the

calculator

or

leave

it

in

areas

exposed

to

high

temperatures

or

humidity,

or

large

amounts

of

dust.

When

exposed

to

low

temperatures,

the

calculator

may

require

more

time

to

display

results

and

may

even

fail

to

operate.

Correct

operation

will

resume

once

the'

calculator

is

brought

back

to

normal

temperature.

•

The

display

will

go

blank

and

keys

will

not

operate

during

calculations.

When

you

are

operating

the

keyboard,

be

sure

to

watch

the

display

to

make

sure

that

all

your

key

operations

are

being

performed

correctly.

•

Replace

batteries

once

every

2

years

regardless

of

how

much

the

calculator

is

used

during

that

period.

Never

leave

dead

batteries

in

the

battery

compartment.

They

can

leak

and

damage

the

unit.

•Avoid

using

volatile

liquids

such

as

thinner

or

benzine

to

clean

the

unit.

Wipe

it

with

a

soft,

dry

cloth,

or

with

a

cloth

that

has

been

dipped

in

a

solution

of

water

and

a

neutral

detergent

and

wrung

out.

•

In

no

event

will

the

manufacturer

and

its

suppliers

be

liable

to

you

or

any

other

person

for

any

damages,

expenses,

lost

profits,

lost

savings

or

any

other

damages

arising

out

of

loss

of

data

and/or

formulas

arising

out

of

malfunction,

repairs,

or

battery

replace-

ment.

The

user

should

prepare

physical

records

of

data

to

protect

against

such

data

loss.

•Never

dispose

of

batteries,

the

liquid

crystal

panel,

or

other

components

by

burning

them.

•

When

the

"Low

battery!"

message

appears

on

the

display,

replace

the

main

power

sup-

ply

batteries

as

soon

as

possible.

•Be

sure

that

the

power

switch

is

set

to

OFF

when

replacing

batteries.

•

If

the

calculator

is

exposed

to

a

strong

electrostatic

charge,

its

memory

contents

may

be

damaged

or

the

keys

may

stop

working.

In

such

a

case,

perform

the

All

Reset

opera-

tion

to

clear

the

memory

and

restore

normal

key

operation.

•

Note

that

strong

vibration

or

impact

during

program

execution

can

cause

execution

to

stop

or

can

damage

the

calculator's

memory

contents.

•Using

the

calculator

near

a

television

or

radio

can

cause

interference

with

TV

or

radio

reception.

•Before

assuming

malfunction

of

the

unit,

be

sure

to

carefully

reread

this

manual

and

ensure

that

the

problem

is

not

due

to

insufficient

battery

power,

programming

or

opera-

tional

errors.
