Te Hiko / Whakaweto
- Hei whakakā: Pēhia te ON/C kī.
- Hei whakaweto: Pēhi Te Whare Tuarua katahi WATE (usually located above the ON/C key).
Display Modes (WriteView / Line)
The calculator features a WriteView display that shows fractions, roots, and formulas as they appear in textbooks. You can switch to a traditional line mode if preferred.
- To toggle between WriteView and Line mode: Press MODE and select the desired display option. Refer to the on-screen menu for specific selections.
Nga Mahi Waihanga Taketake
Enter numbers and operations in sequence. The D.A.L. (Direct Algebraic Logic) input method allows you to input equations exactly as they are written.
- Tāpiritanga: +
- Tangohanga: -
- Whakarea: x
- Wehenga: ÷
- Ōrite: =
Nga Mahi Putaiao
The calculator includes 414 pre-programmed functions covering statistics, n-base calculations, logical operators, trigonometry, logarithms, and more. Access these functions using the dedicated keys or by pressing Te Whare Tuarua followed by the key with the desired secondary function.
- Taumahinga Trigonometric: hara, cos, tan and their inverse functions (accessed via Te Whare Tuarua).
- Ngā Mahi Tauira: rangitaki, ln.
- Ngā Mahi Mana me te Pūtake: x², √, xʸ.
- Tauanga: Enter STAT mode via MODE to perform statistical calculations.
- N-Base Calculations: Perform calculations in binary, octal, decimal, and hexadecimal bases.
Nga Mahi Mahara
The calculator features 4 shortcut memory buttons (D1, D2, D3, D4) for quick access to frequently used functions or constants. Additionally, standard memory functions (M+, M-, RCL, STO) are available.
- STO (Toa): Stores a value into a memory variable.
- RCL (Whakamahara): Recalls a value from a memory variable.
- M+ / M-: Adds to or subtracts from the independent memory.

Te tiaki
Te horoi
Hei horoi i te tātaitai, murua mārire ki te kakahu ngohengohe, maroke. Kaua e whakamahi i ngā kaihoroi whakakoi, ngā whakarewa, ngā kakahu mākū rānei, nā te mea ka kino pea te pūnaha.asing ranei nga waahanga o roto.
Rokiroki
When not in use for extended periods, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. Keep it in its protective cover to prevent scratches and damage.
Tiaki Pūhiko
If the calculator will not be used for a very long time, it is advisable to remove the LR44 battery to prevent potential leakage and damage to the device.
Raparongoā
Whakaatu Take
- Whakaaturanga Pātea: Check battery level. Replace the LR44 battery if necessary. Ensure sufficient light for solar operation.
- Whakaaturanga ngoikore: This may indicate a low battery. Replace the LR44 battery.
Nga Tatau Hapa
- Hua Hē: Verify the input method (D.A.L.) and ensure all values are entered correctly. Check if the calculator is in the correct mode (e.g., DEG/RAD for trigonometric functions, STAT mode for statistics).
- Karere Hapa: Refer to the calculator's on-screen error codes (if any) for specific issues. Common errors include division by zero or invalid function arguments.
Te tautuhi i te Calculator
If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the small reset button (often on the back or side, requiring a thin object like a paperclip to press) or perform a soft reset via the WHAKATAHI menu. Note that resetting may clear all memory and settings.
