Postavljanje

Battery Installation and Power Source

The OSALO Scientific Calculator OS 991ES PLUS II operates on both solar power and a single LR44 battery (included). The solar panel provides power in sufficient light, while the battery ensures operation in low-light conditions or when solar power is insufficient.

1. Provjerite je li kalkulator isključen.
2. Pronađite odjeljak za baterije na stražnjoj strani kalkulatora.
3. Po potrebi otvorite poklopac baterije malim odvijačem.
4. Insert the LR44 battery, ensuring the correct polarity (+/-).
5. Čvrsto zatvorite poklopac baterije.

The calculator will automatically switch between solar and battery power as needed. For optimal performance, use the calculator in a well-lit environment.
