Setup
Sors tal-Enerġija
The Casio DS-2B-GD-W-DP calculator operates using a dual power system: solar power and battery power. It automatically switches between these sources based on ambient light conditions.
- Enerġija Solari: The calculator is powered by solar cells when sufficient light is available. Ensure the solar panel, located above the display, is exposed to light for operation.
- Qawwa tal-batterija: When light is insufficient, the calculator automatically switches to battery power. No user intervention is required for this transition.

Funzjonijiet tal-Memorja
The calculator includes independent memory functions for storing and recalling values.
- M+: Iżżid il-valur muri mal-memorja.
- M-: Inaqqas il-valur muri mill-memorja.
- MR: Ifakkar il-valur maħżun fil-memorja fuq id-displej.
- MC: Clears the memory.
Kalkolu tat-Taxxa
The calculator features dedicated keys for tax calculations.
- TAXXA+: Adds tax to the displayed value.
- TAXXA-: Subtracts tax from the displayed value.
Note: The tax rate must be set prior to using these functions. Refer to the full Casio manual for detailed instructions on setting the tax rate.

Manutenzjoni
Tindif
- Imsaħ il-kalkulatur b'ċarruta ratba u niexfa.
- Għal ħmieġ iebsa, ħafif dampLaħlaħ id-drapp bl-ilma u deterġent ħafif, imbagħad imsaħ niexef immedjatament.
- Do not use strong solvents, abrasive cleaners, or spray cleaners directly onto the calculator.
Ħażna
- Aħżen il-kalkulatur f'post frisk u niexef 'il bogħod mix-xemx diretta u minn temperaturi estremi.
- Avoid exposing the calculator to excessive moisture or dust.
Sostituzzjoni tal-batterija
The calculator uses a button-cell battery as a backup power source. If the display becomes dim or unresponsive in sufficient light, the battery may need replacement.
