Жайгашуу

Батарея орнотуу

Your OSALO Scientific Calculator comes with an LR44 battery pre-installed. The calculator also utilizes solar power for extended battery life and operation in well-lit environments.

1. Калькулятордун ӨЧҮК экенин текшериңиз.
2. Калькулятордун артындагы батарея бөлүкчөсүн табыңыз.
3. Батарея бөлүкчөсүнүн капкагын ачуу үчүн кичинекей бурагычты колдонуңуз.
4. If replacing, remove the old LR44 battery.
5. Жаңы LR44 батареясын оң (+) тарабын өйдө каратып салыңыз.
6. Батарея уясынын капкагын ордуна коюңуз жана аны бурама менен бекитиңиз.

Note: The solar panel assists in powering the calculator in sufficient light, reducing reliance on the battery.
