Ukufaka/Ukushintsha Ibhethri:

1. Ensure the calculator is turned off or in a well-lit area to utilize solar power.
2. Thola isembozo segumbi lebhethri ngemuva kwesibali.
3. Susa ikhava ngokucophelela.
4. Insert a new LR-54 or LR44 battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
5. Shintshanisa ikhava yengxenye yebhethri ngokuphephile.

Note: The calculator may power on automatically once sufficient light or battery power is detected.

5. Iziqondiso Zokusebenza

Ukusebenza Kwezibalo Eziyisisekelo:

Enter numbers and use the standard arithmetic keys (+, -, ×, ÷) followed by the equals key (=) to perform calculations.

• Ukwengeza: [Number 1] [+] [Number 2] [=]
• Ukukhipha: [Number 1] [-] [Number 2] [=]
• Ukuphindaphinda: [Number 1] [×] [Number 2] [=]
• Isigaba: [Number 1] [÷] [Number 2] [=]

Clear Functions:

• [CA/C] (All Clear): Clears all entries and memory, resetting the calculator.
• [CE] (Clear Entry): Clears the last entered number or the current calculation result without affecting previous entries or memory.

Iphesentitage Ukubala:

Ukubala amaphesentitages, use the [%] ukhiye.

• Example: Calculate 15% of 200.
  Ngena [200] [×] [15] [%]. The result will be 30.
• Example: Add 15% to 200.
  Ngena [200] [+] [15] [%]. The result will be 230.

Ukubalwa Kwentela:

The calculator features dedicated keys for tax calculations. First, set the tax rate.

1. Setting the Tax Rate:
   Enter the tax rate (e.g., [8] for 8%). Press [RATE SET]. The tax rate is now stored.
2. Adding Tax:
   Enter the amount (e.g., [100]). Cindezela [+TAX]. The display will show the amount with tax added.
3. Subtracting Tax:
   Enter the amount (e.g., [108]). Cindezela [-TAX]. The display will show the amount with tax removed.
4. Recalling Tax Rate:
   Cindezela [RATE RECALL] ku view the currently set tax rate.

Imisebenzi Yenkumbulo:

The 4-key memory allows you to store and recall values.

• [M+] (Memory Plus): Adds the displayed value to the memory.
• [M-] (Memory Minus): Subtracts the displayed value from the memory.
• [RM] (Recall Memory): Displays the value currently stored in memory.
• [CM] (Clear Memory): Clears the memory content. (Often combined with RM, pressing RM twice clears memory).

Ukubalwa kwe-Square Root:

To calculate the square root of a number, enter the number and then press the [√] ukhiye.

• Example: Calculate the square root of 81.
  Ngena [81] [√]. The result will be 9.

6. Isondlo

• Ukuhlanza: Use a soft, dry cloth to clean the calculator's exterior. For stubborn dirt, slightly dampen the cloth with water and a mild detergent, then wipe dry immediately. Do not use abrasive cleaners or solvents.
• Isitoreji: When not in use for extended periods, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures.
