How to confirm the quality of a calculator:
1. When the calculator's power is supplied by double-power AA batteries or a solar panel, first remove the AA batteries, check if the solar panel has a digital display, and if the display is not clear, please sway it within the light secondary area. When the screen displays the character "0", it can be proven that this solar panel is functioning normally.
2. At any time, you just need to input '8÷9' and then press the '+8' key. If your calculator is a 12-digit model, the screen will display a 12-digit '8', and if it's an 8-digit model, the screen will display an 8-digit '8'. The next step is to carefully check the clarity of each '8' character and whether there are any missing parts. If there are no such two situations, it can be indicated that your calculator is normal.
