The calculator comes with one LR44 battery pre-installed. If the display becomes dim or unresponsive in low light, the battery may need replacement.

1. Turn the calculator OFF.
2. Sib il-kompartiment tal-batterija fuq wara tal-kalkulatur.
3. Bl-użu ta' tornavit żgħir, iftaħ l-għatu tal-kompartiment tal-batterija.
4. Neħħi l-batterija LR44 il-qadima u daħħal waħda ġdida, waqt li tiżgura l-polarità korretta (+/-).
5. Ibdel l-għatu tal-kompartiment tal-batterija u waħħalha.
