Frequently Asked Questions - X Mark I Pro CANON

How do I replace the battery?

Locate the battery compartment on the back, slide the cover off, remove the old LR44 battery, insert a new one with the positive side facing up, and replace the cover.

Why is my calculator not turning on?

Ensure the solar panel is receiving light in a bright environment. If still off, the backup battery may be drained. Replace the LR44 battery or check the solar panel connection.

How do I reset the calculator?

Press the AC (All Clear) button to clear the current calculation. For a full reset, remove the battery for 10 seconds and reinsert it.

What does 'E' or 'Error' mean?

The E indicates an overflow or division by zero. Press AC to clear the error and start a new calculation.

How do I use the memory functions?

Use M+ to add the displayed number to memory, M- to subtract, MR to recall the stored value, and MC to clear memory.

Can I use the calculator without the backup battery?

Yes, in adequate light the solar cell powers the calculator. However, the backup battery is needed to retain memory when light is insufficient.

How should I clean my calculator?

Wipe the exterior with a soft, dry cloth. Do not use water, alcohol, or abrasive cleaners as they may damage the plastic.

Is the calculator suitable for advanced math?

This model is designed for basic arithmetic and simple scientific functions like square root and percentage. It does not support complex algebra or graphing.

What is the warranty period?

Canon provides a 1-year limited warranty against manufacturing defects. Keep your purchase receipt for claims.

How do I open the sliding cover?

Hold the calculator with one hand and slide the cover upwards (away from the keys) with the other hand. It clicks into place when open.

Inputting Expressions and Values

Input Capacity

X Mark I Pro allows you to input a single calculation with up to 99 bytes. When input capacity is less than 10bytes, the input cursor will change from “I” to “■” signaling that the memory is running now.

Input Editing

■ New Input begins on the left of display. When the input data is more than 15 characters (Line Mode) / 16 characters (Maths mode), the line will scroll to the right consecutively. You can scroll back to the left by using ◀ and ▶ to review the input.
■Dmit the multiplication sign and final close parenthesis.

Example: 2 x log 100 x (1+3) = 16 ...... EX #1

*1. Omit multiplication sign (x)

• Input before an open parentheses (1) x (2+3)
• Input before scientific functions that includes parenthesis: 2 x cos(30)
• Input before Random number function Rand
• Input before Variable (A, B, C, D, X, Y, M), π, θ

*2. Scientific functions come with the open parenthesis. Example: (·) , (·) , Pol(·) , LCM(·) . You need to input the argument and the close parenthesis [ ] .

*3. Omit the last close parenthesis before the , M+, M-, Sh and STO.

■ Insert and Overwrite Input mode

In Line mode, you can use INSERT Insert or overwrite mode for inputting.

In Insert mode (Default input mode), the cursor is a vertical flashing line "I" for inserting a new character.
- In Overwrite mode, press Shift Insert key to switch the cursor to a flashing horizontal “_” and replace the character at the current cursor position.

In Mathematics mode, you can only use the insert mode.

Whenever the display format changes from Line mode to Mathematics mode, it will automatically switch to the insert mode.

■ Deleting and Correcting an Expression

In Insert mode: Move the cursor to the right of the character or function that needs to be deleted, then press DEL. In Overwrite mode: Move the cursor under the character or function being deleted, then press DEL.

Example: 1234567 + 889900

EX #2
(1) Replace an entry (1234567 → 1234560) ..... EX #2
(2) Deletion (1234567 → 134567)..... EX #3
(3) Insertion (889900 → 2889900) ...... EX #4

Inputting and Display Result in Mathematics Mode

In Mathematic Mode, the Input and display result of fraction or certain functions (log, x² , x³ , x , √- , √[3]- , √- , x¹ .10', e', Abs) is shown in Handwriting/Mathematics format.

EX #5

(1) Some input expressions cause the height of a calculation expression to be greater than one display screen. Maximum input capacity: 2 display screens (31 dots x 2).

■Display of results using √

Calculation results may be displayed using √ when in all of the following cases:

1. When intermediate and final calculation results are displayed in the following form:

± a √ bc ± d √ ef

0 ≤ a lt; 1 0 0, 1 ≤ d lt; 1 0 0

0 ≤ b lt; 1 0 0 0, 1 lt; e lt; 1 0 0 0

1 ≤ c lt; 1 0 0, 1 ≤ f lt; 1 0 0

1. When the number of terms in the intermediate and final calculation result is one or two.

Order of Operations

This calculator will automatically determine the operation priority of each individual command as EX #7

Cubic equation : ax ³ + bx² + cx + d = 0 (an equation with cubic polynomial)

Quart equation : ax ⁴ + bx³ + cx² + dx + e = 0

Example: Solve the cubic equation 5x³ + 2x² - 2x + 1 = 0

EX #45

Solve Function

■You can solve custom calculation expressions in COMP mode. Simply input the expression with different variables and press the Shift key.

• Solves for X , for example, when an equation is input as: X = Y + 5 , X
• Solves for Y, for example, when an equation is input as: Y = X + 5 , Y

Example: A cone with height "h" and a circular base with radius "r"; find the cone volume using this formula:

V = 1/3 πr ^ 2 h [X = 1/3 πB ^ 2 C ]

Replace the variable "V" with X, variable "r" with "B", and variable "h" with "C".

■ Radius is 5cm, cone height is 20cm, calculate the cone volume. And if the cone volume is 200cm³ , with radius 2cm, calculate the cone height. ..... EX #46

! If the expression does not have the equal sign (=) and perform the Solve calculation, the calculator will transform the solution as zero (0).
! Solve function cannot be solved an equation.
! When the expression cannot be solved, [Solve ERROR] will be displayed.

CALC Function

■CALC function is a memory zone with a maximum of 79 steps to store a single calculation expression which can be recalled and calculated a number of times with different values.
■After inputting the calculation expression and pressing the calculator will request for the current value of your input variables.
■CALC function can only be used in COMP mode or CPLX mode.

Example: For the equation Y = 5x² - 2x + 1 , calculate the value of Y if x = 5 or x = 7. ..... EX #47

! The CALC stored expression will be cleared as you start a new calculation, change into another mode, or turn off the calculator.

Differential Calculations

■Press MODE 1to enter COMP mode.

To perform a differential calculation, you have to input the expression in the form of:

Shift 4 differential expression a x )

• The differential expression must contain the variable x.
• "a" is the differential coefficient.
• "△x" is the change interval of x (calculation precision).

Example: To determine the derivative at point x = 10, x = 10⁸ , for the function f(x) = (3x + 30) . ..... EX #48

! You can leave out the x in the differential expression and the calculator will automatically substitute a value for x .
! The smaller the entered value Δx is, the longer the calculation time will be with more accurate results, the larger the entered value Δx is, the shorter the calculation time will be with comparatively less accurate results.
! Discontinuous points and extreme changes in the value of x can cause inaccurate results or errors.
! When performing differential calculations with trigonometric functions, select radian (Rad) as the angle unit setting.
! Log _a b, i\~Rand, Rec ( and Pol ( functions can not join to differential calculations.

Integration Calculations

■Press MODE 1 to enter COMP mode.
■To perform an integration calculation you are required to input following elements:

integration expression 'a' 'b', 'n')

• The integration expression has a variable x.
- "a" and "b" defines the integration range of the definite integral.
- "n" is the number of partitions (equivalent to N = 2ⁿ ).

■The integration calculation is based on Simpson's rule.

_ a ^ b f (x) dx, tol

As the number of significant digits is increased, internal integration calculations may take considerable time to complete. For some cases, even after considerable time is spent for performing a calculation, the calculation results may be erroneous. Particularly when significant digits are less than 1, an ERROR might be occurred.

Example: Perform the integration calculation for

_ 2 ^ 3 (5 x ^ 4 + 3 x ^ 2 + 2 x + 1) dx, with n = 4. ... ... . EX # 4 9

! When performing integration calculations with trigonometric functions, select radian (Rad) as the angle unit setting.
! Log _a b, i\~Rand, Rec ( and Pol ( functions can not join to integration calculations.
