REPLACING THE BATTERY
Although your calculator uses solar power most of the 
time, the supplied backup battery will eventually become 
weak and need to be replaced. If the display dims or the 
calculator speed slows down, replace the battery with a 
type 389A button-cell battery. For the best performance 
and longest life, we recommend alkaline batteries.
