Modifying or tampering with the calculator’s internal com-
ponents can cause a malfunction and might invalidate its
warranty. If your calculator is not performing as it should,
take it to your local electronic store for assistance.

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.

Follow these steps to replace the battery.

1. Place the calculator face down on a flat surface.

2. Use a Phillips screwdriver to remove the screw secur-

ing the back cover.

3. Slide the back cover down to remove it.

4. Remove the old battery.

5. Position the new battery so the positive (+) side is up,

then press the battery into the battery holder.

6. Slide the front and back case halves back together,

then reinsert and tighten the screw.
