Kun żgur li l-kalkulatur ikun mitfi.
Sib il-kompartiment tal-batterija fuq wara tal-kalkulatur.
Bl-użu ta' tornavit żgħir, iftaħ l-għatu tal-kompartiment tal-batterija bir-reqqa.
Remove the old LR44 battery (if replacing).
Insert a new LR44 battery with the positive (+) side facing upwards.
Agħlaq sewwa l-għatu tal-kompartiment tal-batterija.
Turn on the calculator to verify proper installation.

Nota: The calculator comes with one LR44 battery included.
