INTRODUCTION
Thank you for your purchase of the SHARP scientific calculator, model EL-506H.
This manual will introduce you to the Sharp EL-506H scientific calculator.
Each section in this manual may be divided into basic and advanced material. The
advanced material is labeled "supplementary." The supplementary sections may be
skipped without hampering your ability to operate the calculator. You may wish to
return to the supplementary sections as your skill in operating the EL-506H
OPERATIONAL NOTES
Since the liquid crystal display is made of glass material, treat the calculator
with care. Do not put the "EL-506H" in your back pocket as it may be
damaged when you sit down.

To insure trouble-free operation of your SHARP calculator, we recommend the fol
lowing:
1. The calculator should be kept in areas free from extreme temperature changes,
moisture and dust.
During summer weather, vehicles left in direct sun light are subject to high tem
perature build up.
Prolonged exposure to high temperature may cause damage to your calculator.
2. A soft, dry cloth should be used to clean the calculator. Do not use solvents or a
wet cloth.
3. If the calculator will not be operated for an extended period of time, remove the
batteries to avoid possible damage caused by battery leakage.
4. If service of your calculator is required, use only an authorized SHARP service
center.
5. Keep this manual for further reference.
Name label
Write your name on the attached name label and stick it on the back of the
calculator.

Scientific Functions
• Direct formula entry for entering formulas as they are written with no need
for translation into machine language.
Example 5 + 2 x sin 30 + 24 x 5' =
Operation CEl E [2][X] [B foil sin I [+1 FB [4]
[X] (T][S[I] S
• 3 levels of parentheses and 4 levels of pending operations for solving more
complicated formulas.
• Hexadecimal <-► decimal notation conversion
Hexadecimal notation system is mainly used in computer programming.
Computer engineers and programmers have been in urgent need for a simple
conversion of decimal and hexadecimal notations.
Now, EL-506H has solved the problem. Simply enter a number in base 16 or
10, the EL-506H will then give you the answer instantly.

• Preprogrammed for 48 functions: trigonometric. Inverse trigonometric, logari
thmic, hyperbolic, arc hyperbolic, statistical and others.
Useful Keys for Solutions of Math Problems
• Statistical calculations with statistical mode [STAT], number of samples/S;*:
[nSA:], mean/Sx^ [je 1, standard deviation [so], enter data/correct data
[DATA CD] keys.
• Independently accessible memory.
• DEG/RAD/GRAD selector key.
• Degree/minute/Second conversion key for decimal degree transformation.

priority level
The machine, provided with a function that judges the priority level of individual
calculations, permits keys to be operated according to a given mathematical formula.
The following shows the priority level of individual calculations.
(1) Function m+
(2)
(Calculations which are given the same priority level are
' executed in sequence.)
(4) +, —
(5) =, A%,
The calculation in parentheses has priority to others.
