INTRODUCTION
Dear customer,
Congratulations on your purchase of this ad -
vanced personal electronic calculator.
Th is sophisticated mode l has 10 special keys
making it highly valuable for scientific and all
ki nd of research work.
Besides the basic capabilities as ordinary personal
ca l culator -constants in all 4 basic functions,
fu ll floating decimal system, and a handy palm-
sized style - this model is equ i pped with capa-
bilities for computing 10 specific scientific f nc-
lions at one touch.
To uti lize full features of this calcula to r, no
special training is required but we suggest you
take a
few minutes to be com e fa mil iar w ith this
instr uct ion manual.
It has been writte n to assist you in un derstand i ng
the various contro l keys and fun c tions of the
calculator through s imple examples and their
applications.

2 / HANDLING OF THE
CALCULATOR
Befo re operatio n, please be sure to check th e
pro per setting of the dr y batte ri es or co nne c-
tion of the AC Adaptor.
The calculator should be o perated correctly in
accordance with this instruction manual with
firm and separ
ate key pr essing. Two or more
numeral andlor comm and keys should not be
pressed simultaneously,
as this may damage
the m ac hine.
:3 / DISPOSABLE DRY BATTERY
OR AC OPERATION
This ca lculator ope rates on either dry batteries or AC with the use of the AC ADAPTOR.
3-1 DRY BATTERY OPERATION
With fo ur Alkaline dry batte ries (AM·3J it ope r at es for approximate ly 17 hours continuously. Even
when
batte ry power decreases, th e display will merely darken b ut cause no miscalculation,
When you have finished
your calcu l at i on, be su re to switch off the power switch to save battery
power .
To cha n ge batter ies, put the power switch off first. Slide open the battery cover and re place batte ries.
3-2 AC OPERATION
If you are in a 117V area, for instance. use a 117V AC ADAPTOR.
When, you use an AC ADAPTOR of a differe nt vol tage, it may cause dama ge to both the AC
ADAPTOR a nd calculator.
Plug
the applicab le AC ADAPTOR (100, 117, 220 or 240V) into the AC outlet and the cord in to
the calculato r. When plugged in, battery power supply stops automa tically, so b attery power is
not wasted,
4 / 0VERFLOW
Princip al ly. overfl ow occurs when the integer part of an answer exceeds 8 digits 17 , when the f ig ure
is negative) and stops furthe r calculation, showing D's (zeroes) on all columns.
In function calculations, however, th e overflow also occurs in the following instances:
a) When either a common or natu ral logarit hm of 0 (zero) is obtained
b) When the
trigonom etric functions are perf orme d for a degr ee exceeding ± 1440 °
c) When the exponentia l function is performed for a num ber exceed in g :1: 10.
d) When the answer of a Ta ngent is larger than ±1000.
Depress th e ell key to release the ove r f l o~ check pri or to starting a new calculation.

5 / BASIC OPERATIONAL EXAMPLES
Press the keys in exactly the same ,sequence as they appear in the problems. There is no need to
depre ss the 13 or a key prior to starting each new calculation, as automatic clearing takes place
wit h the new en tr y when you ha .... e finished the previous ca lculation on the e key.
When the answer
is negative, the minus (~) sign appe ars on the teft of the f igu r e.

Note : When u nder fl ow works in addition / subtraction wi th a constant, the deci mal places of the

For instance. if you perform 12345.6 + 0.1234 = 12345.723(4), 0.123 is set as a constant
instead of 0.1234, as the least significa nt decimal digit is dropped off by the underflow.

a / FUNCTION CALCULATION
This calculator computes 10 specific scientific functions at one touch independent of the basic
ar ithm e tic cal culations.
So it is necessary to change the order of operation when you desire to use some of the sc ie nt ifi c
functions as a subrout ine of the basic calculat ion, in order to perform the sc i entific functions
first a nd to u se the result in basic calculations.
For example, when you perform such an operat ion as [5 x sin 30 ° ], ca lculate [sin 30 " ] first and
mult iply 5 to the answer of [sin 30 ° I on display.
However, the 0 , ~ , lO and mkeys can be used as subroutine in the midst of basic calculation s.
Note that automatic clearing is also made in function calcu lati ons and there is no need to depre ss
the C3 key prior to s tarting the new problem.
* This calcula tor computes as 1T = 3.141592 and e = 2.7 182818 respectively.
SEXAGESIMAL -+ DECIMAL CONVERSION
The 8 key conve rt s the sexagesimal figur es (Degree, Minute ,and Second) to decima l scale.
