3. Gosod

3.1 Ffynhonnell Pwer

The Sharp EL-W531 calculator operates using both solar power and a single AAA battery. The solar panel provides power in well-lit environments, while the battery ensures operation in low-light conditions.

3.2 Gosod/Amnewid Batri

1. Gwnewch yn siŵr bod y gyfrifiannell wedi'i diffodd.
2. Lleolwch glawr adran y batri ar gefn y gyfrifiannell.
3. Gan ddefnyddio sgriwdreifer bach, tynnwch y sgriw sy'n sicrhau'r clawr yn ofalus.
4. Llithrwch y clawr i ffwrdd.
5. Remove the old AAA battery (if applicable) and insert a new AAA battery, ensuring correct polarity (+/-).
6. Amnewid gorchudd adran y batri a'i ddiogelu gyda'r sgriw.

3.3 Pŵer Cychwynnol Ymlaen
