THE KEYBOARD AND OPERATING
CONTROLS
SD
(1)   [ON/C ]   :  1. Power on and clear an error condition.
2. Set and clear the statistics mode.

x!
(2)   [CE ]   :  1. Clear entry key.
2. Factorial function (x!).
x! = n x (n–1) x (n–2) x (n–3) x .....x 2 x 1
(3) [OFF] : Power off key.
(4) [SHIFT] : This is the key for specifying the second function. When
this key is pressed, the special display “SHIFT” lights.
When this key press twice continuously, the second
function mode releas.
(5)   [DRG ] : a. Pressing this key will change the mode of angle unit
sequentially             DEG     RAD  GRAD     and display it
on LCD.
b. Pressing this key after [SHIFT] key shall change the
mode of angle and shall convert the displayed data.
DEG > RAD : RAD = DEG x    ?/180
RAD > GRAD : GRAD = RAD x 200/?
GRAD > DEG : DEG = GRAD x 180/200
(6)  [0] ~ [9] : Press these keys in their logical sequence to enter
numbers.
RND
(7)   [     ]     : a. Use to set the decimal point when entering numbers.
b. When press as the first number, it is regarded as [0]
and [ • ] keys are pressed.
c. Random as a second function.
Pressing this key shall display the random number.
The range of random number is 0.000~0.999.
(8) [+/–] :  a.  In setting data in the mantissa section, this key reverse
code in the mantissa section similarly for exponent
section, it reverse code in the exponent section.
b.  For the operation result, this key reverse code in the
mantissa section.
(9) [+], [–], [x], [ ? ], [ ( ], [ ) ]
a. When the key operations  are performed by these keys
according to a numerical expression, a result of operation is
obtained according to  mathematical priorities. Priorities
discriminated are:
1) 1-variable function.
2) Expression in "(    )"; (The most inner expression has priority
in case of multiple parenthesis)
y
3) x ,   y  x
4) x, ?
5) +, –
