[-]
Minus symbol
Indicates that the displayed number is negative
[M]
Memory symbol
Displayed when a number is stored in calculator’s memory.
[E]
Error symbol
Displayed when overflow or error is detected.
[2ndF]
Second function symbol
Displayed when second function is selected.
[hyp]
Hyperbolic function symbol
Displayed when hyperbolic function is selected.
[DEG]
Degree mode symbol
Displayed when the calculator is in degree mode or when results are displayed
in degrees.
[RAD]
Radian mode symbol
Displayed when the calculator is in radian mode or when results are displayed
in radians.
[GRAD]
Gradian mode symbol
Displayed when the calculator is in gradian mode or when results are displayed
in gradians.
[( )]

hexadecimal number.
[CPLX]
Complex symbol
Displayed when the calculator is in complex number mode.
[STAT]

3. Display system
The calculator displays the result from calculation (x) with floating point if it is in
the range 0.000000001 ≤ x ≤ 9999999999, otherwise the calculator displays x
in scientific notation. It is still possible to display numbers in the range above in
scientific notation by pressing the
[F↔E]
key.
E.g.
[2ndF][TAB][9]
(displays 9 decimals after decimal point)
[.][5][÷][9][=]
(displays 0.055555556, tenth decimal rounded)
[F↔E]
(displays 5.5555555-02, tenth decimal of mantissa rounded)
[F↔E]
(displays 0.055555556, tenth decimal rounded)
[2ndF][TAB][.]
(displays 0.055555555)
The calculator calculates this in format 5.55555555556x10
-2
. By rounding the
11th digit in the mantissa, the number will be 5.55555555556x10
-2
. Rounded
parts may not be displayed as in this example when you shift between floating
decimal point and scientific notation.
Battery change
If the display turns dark or weak, change batteries according to the following.
Type of battery: 2 batteries. L1131 or /LR1130 / SR54 / AG10.
1. Turn off the calculator.
2. Open the two screws in the battery hatch. Remove battery hatch by sliding
it in the direction of the arrow.
3. Change batteries. (+ facing upward)
4. Replace battery hatch.
5. Press
[OFF]
and
[ON/C]
keys after each other after the change of batteries
to reset the calculator. ”DEG 0” is shown on the display. If the display is
blank, shows the wrong characters or that the calculator does not function,
remove the batteries and replace them. Press
[OFF]
and
[ON/C]
keys after
each other and check the display again.
NB!
• Always change both batteries.
• The manufacturer reserves the right to change data and functions without
any preceding notification.
