Data input precautions
D inputs the same data twice.
D You can also input multiple entries of the
same data using . To input the data
"20 and 30" five times, for example, press
20 30 5 .
D The above results can be obtained in any
order and not necessarily that shown
above.
D To delete data you have just input, press
.
Degrees, Minutes, Seconds calculations
D You can perform sexagesimal calculations
using degrees (hours), minutes and se-
conds and convert between sexagesimal
and decimal values.
Example 1.: To convert the decimal value
2.258 to a sexagesimal value
2.258
J Technical Information
When you have a problem...
If calculation results are not what you expect or
if an error occurs, perform the following steps:
1. (COMP mode)
2. (DEG mode)
3. (NORM 1 mode)
4. Check the formula you are working with to
confirm it is correct.
5. Enter the correct modes to perform the cal-
culation and try again.
If the above steps do not correct your problem,
press the P button on the back of the calculator
to reset it. Pressing the Reset" button deletes all
data stored in calculator memory. Make sure you
always keep written copies of all important data.
J Error messages
The calculator is locked up while an error mes-
sage is on the display. Press to clear the error
or press or to display the calculation and
correct the problem.
Ma ERROR
D Cause
D Calculation result is outside the allowable
calculation range.
D Attempt to perform a function calculation
using a value that exceeds the allowable
input range.
D Attempt to perform an illogical operation
(division by zero, etc.)
D Action
D Check you input values and make sure they
are all within the allowable ranges. Pay spe-
cial attention to values in any memory
areas you are using.
Stk ERROR
D Cause
D Capacity of the numeric stack or operator
stack is exceeded.
D Action
D Simplify the calculation. The numeric stack
has 10 levels and the operator stack has 24
levels.
D Divide your calculation into two or more se-
parate parts.
Syn ERROR
D Cause
D Attempt to perform an illegal mathematical
operation
D Action
D Press or to display the calculation
with the cursor located at the location of the
error. Make necessary corrections.
Arg ERROR
D Cause
D Improper use of argument
D Action
D Press or to display the location of
the cause of the error and make required
corrections.
J Order of operations
Calculations are performed in the following order
of precedence.
1. Coordinate transformation:
Pol (x, y) Rec (r, )
2. Type A functions: With these functions, the
value is entered and then the function key
is pressed.
x

6. Type B functions: With these functions, the
function key is pressed and then the value
is entered.

8. Permutation and combination: nPr, nCr
9. X , ÷

Operations of the same precedence are perfor-
med from right to left, e

In 120 > e
X
{In( 120)}.
Other operations are performed from left to right.
Operations enclosed on parentheses are perfor-
med first.
J Stacks
This calculator uses memory areas, called
"stacks", to temporarily store values (numeric
stack) and commands (operator stack) accor-
ding to their precedence during calculations. The
numeric stack has 10 levels and the operator
stack has 24 levels. A stack error (Stk ERROR)
occurs whenever you try to perform a calculation
that is so complex that the capacity of a stack is
exceeded.
D Replacing the battery
Dim figures on the display of the calculator indi-
cate that battery power is low. Continued use of
the calculator when the battery is low can result
in improper operation. Replace the battery as
soon as possible when display figures become
dim.
D To replace the battery
1. Press to turn power off.
2. Remove the screws that
hold the battery cover in
place and then remove the
battery cover.
3. Remove the old battery.
4. Wipe off the side of the new
battery with a dry, soft cloth.
Load it into the unit with the
positive side facing up
(so you can see it).
5. Replace the battery cover
and secure it in place with
the two screws.
6. Use a thin, pointed object to press the Re-
set button. Be sure not to skip this step.
7. Press to turn power on.
D Auto power off
Calculator power automatically turns off if you do
not perform any operation for about six minutes.
When this happens, press to turn power back
on.
