FEATURES

The

CE·l

59

is

a program module with

an

8 K

by

te memory capacity

RAM

(o.apablc

of

being

entered

or

read) for use on the

PC

·

1500

. Itcan be used to

as.s

ign

a

part

of

the

RAM

capacity as an area for exclusi

ve

use in readouts, allowing no entry

of

new

data

or

pro·

gram change into the area.

Ev

en when disconnected from the PC·1

500.

the CE·159

retains the p

ro

y

ra

rn contents in this area due to

it

~

built-in lithium

ce

ll. This isavailable

for

imm

edi

ate

use

when

reconnect

ed

to t

he

computer

.

Therefore,

if

programs are stored in several CE-159 modules, they

can

l>e

executed only

by

When

the

CE·159

is

used as a RAM area, the reserve area can

be

secured inside

the

mod·

ule, as illustrated. (The reserve area inside the

PC

·1500 can be cleared.) The BASIC

program is written from the CE·159, while variables are

secured

from the PC·1500.

With

the

CE·159 connected

to

the

PC·

1

500,

the

tota

l memory capacity becomes

10

K

bytes

including t

he

reserve area.

When

U$Cd

as a

RAM

area, this rnemory

capacity

makes

it

possible

to

write

a program,

secure variables, char\ge and write the r

eserve

contents.

When an e:xclusive readout area is set, writing

or

program change in this area

becomes

im

·

possible. Therefore, only

the

remaining

RAM

areacan

be

used as variable$. (The reserve

a

te

a can

also

be

made

f

or

exclusi

ve

use

in readouts. making writi

ng

or program change

impossible.t

CELL LIFE

AND

REPLACEMENT

Cell

life

The

life

of

a lithium cell in

the

CE·159

is

about

5 years at normal temperature (25°C)

when

the

CE·159

is

connec

ted

to

the computer,

Md

about

2 years

when

disconnected

from the computer. The contents

of

the

CE·t 59 can

be

therefore r

etained

for these

periods

of

time, respectively.

The CE·

159

is provided with the following

da

ta label:

This

data

indicates

the

day when the

li

thium cell

is

placed

in

the

CE.·159. The cell

life

in

t

he

CE-159

is about 5 years or 2 years according to this date u

nder

normal tem·

perature

(25

°C}

. However. it

may

be

s

horte

ned depending on

an

oper

ating

en

vironm

ent

where

th

e temperature

is

too

high or

too

low. causing the program in the exclusiYe read·

out

a

re

a

to

disappear.

To

prevent th

is,

it

is

recornmended that you

re

cord the program

or

data Or'1 tape

for

storage.

When

battery

power declines, the following will occur:

(1} Program execution

is

not

pos.sib

lc.

(2) lncor

rr

ect displays are indicated.

(3) Errors take place.

For trouble-free operation, replace the

ce

at

your

nearest Sharp servi

Caution

sh

ould be taken if there

is

a l

apse

of

more than 5 yea

from

th

e date on the

cell label

or

the

ce
