3. Kuweka

3.1. Ufungaji wa Betri

The calculator operates on a Twin Power system, utilizing both solar power and a single LR44 button cell battery. The battery is typically pre-installed. If the display becomes dim or unresponsive in low light, the battery may need replacement.

Hakikisha kikokotoo kimezimwa.
Tafuta sehemu ya betri nyuma ya kikokotoo.
Use a small screwdriver to open the compartment cover.
Ondoa betri ya zamani ya LR44 na uingize mpya, ukihakikisha polarity sahihi (+/-).
Replace the compartment cover and secure it with the screw.

3.2. Nguvu ya Awali Imewashwa

Bonyeza kwa ON/C button to turn on the calculator. The display will show the initial screen. If the display is blank, ensure sufficient light for solar power or check the battery.
