Changing the battery: The backup battery has a long life. If the
display fades, remove both screws on the back cover. To separate
the front and back covers, carefully insert and twist a flat-blade
screwdriver between them. Gently pry out the old battery then
position the new battery so the (+) side is facing up. Snap the
covers back together, then reinsert and tighten the screws.
Caution:
• Danger of explosion if battery is incorrectly replaced.
• Replace only with same or equivalent type recommended
by the manufacturer.
• Dispose of or recycle used batteries according to
manufacturer's instructions.
• Chocking hazard. Keep batteries out of the reach of
children under 6 years of age.
Overflow: When an overflow error occurs, the overflow error sign
"E" appears on the display. Press (C/CE) to reset.
Reset: If the calculator malfunctions, use the tip of a ball point pen
(or similar sharp object) to press the "RESET" button.
