Dear customer,
Tha. nk you very much for purchasing our electronic cal-
culator.
To fully utilize its features no special training is re -
quired, but we suggest you study this operation manual
to become familiar with its many abilities. To help en-
sure its ·1ongevity, do not touch the inside of the cal-
culator , avoid hard knocks and unduly strong key
pressing. Extreme cold (below 32°F or 0 °C), heat
(above 104 °F or 40°C) and humidity may also a ffect
the functions of the calculator. Never use vo latile fluid
such as lacquer thinner, benzine, etc. when cleaning
the unit. For servicing contact your retailer or ne arby
dealer.
Before starting calculation, be sure to press the@E) key
and to confirm that ''O ." is shown on the display.
* Special care should be taken not to damage the un it
by bending or dropping. For example, do not carry
it in your hip pocket.

To put the ca l culator into a desired operating mode,
or to select a specific angular unit, press IMooE] first , then
[:], [QJ, @, ... or [[).
!MooE][:J -SD is displayed. Calculate standard deviation .
[MooE][Q] - COMP mode. Carry out ordinary arithmetic
and functional calcu l ations.
!MODEi@ -DEG is displayed. Use degrees as the unit of
angle measurement .
IMDDEJ[[j -RAD is displayed. Use radians as the unit of
angle measurement ,
IMoDEJ(§] -GRA is displayed. Use grads as the unit of an-
gle measurement .
IMoDE][z] -Press any number from Oto 7 to indicate how
many decimal places you want displayed (FIX
is displayed) .
IMDDEJ(I] -Press any number from 1 (1 digit) to 8 (8
digits) to indicate how many significant digits
you want displayed (SCI is displa~d) .
IMoDEJ[[) -Releases instructions entered in ~[z] and

@Press IMoDEI[[) to switch between the Type A and Type
B lower lim i ts.
* Note that the lower limit is not changed if you press
IMoDEl(ID while the number of significant digits (SCI dis-
played) and/or the number of decimal places (FIX dis-
played) are specified. The first time you press (MODEi[[) ,
you clear the FIX and SCI specifications , and so you
must press IMoDrl[ID again to change the lowe r limit.
2/ ORDER OF OPERATIONS AND LEVELS

precedence:
. ..

1. F unc t ions
2. x >' , x·

Operations with the same precedence are performed
from left to ri ght, with operations enclosed in paren-
theses per formed first. If parentheses are nested , the
ope rat ions enclosed in the innermost set of paren-
theses .are perfo r med first.
*Registers L1 through L6 ·are provided to store opera-
tions of lower precedence (inc luding parenthetica l
ope rations). Since six registers are provided , calcu -
l ations up to six levels can be retained.
*Sin ce each leve l can contain up to three open paren-
theses, paran theses can be nested up to 18 ti mes.

4/0VERFLOW OR ERROR CHECK
Overflow or error is indicated by the
1'- E-
'' or

- [ -'
1
sign and stops further calculation . ·
Overflow or error occurs:
a) When an answer , whether intermediate or final, or
accumulated total in the memory is more than
± 9. 9999999 x 10
99 (' '
-E-' ' sign appears).
b) When function calculations are performed with a
number exceeding the input range ('' - E- '' sign
appears).
c) When unreasonable operat i ons are performed in
statistical calcu l ations (1 1 -E-'' sign appears).
d) When the total number of levels of explicity and/ or
implicity (with addition - subtraction ve~sus
multiplication - division including xY and x1 i;, ) neste d
parentheses exceeds 6, or more than 18 pairs of
parentheses are used (''-[ -'' sign appears).
Ex.) You have pressed the ((,, .. j key 18 times continu-
ou~ before designating the sequence of
~000£1.
To release these overflow checks:
a), b)I c) ..... ... Press the m9 key .
d).... ..... ......... Press the m9 key. Or press the l!J key ,
and the intermed i ate result just before
the overflow occurs is displayed and
the subsequent calculation is possible.
Memory protection:
The content of the memory is protected against over -
flow or error and the accumulated total is recalled by
pressina..!_he IMR j key after the overflow check is released
by the FD key.
