ERRORS
When an incorrect attempt to convert between liquid measures, dry meas-
ures, or temperature occurs, the calculator will display the word “Sorry” for a
few seconds before showing the initial value on the display. If an error is dis-
played, press any key.
RESET
If your calculator’s display should ever freeze, or “lock up,” press Reset—a
small hole located to the right of the [On/C] key—using the end of a paper
clip.
ACCURACY
Each calculation is carried out internally to 10 digits.
AUTO SHUT-OFF & BATTERY
Auto Shut-Off: After 11 min. of non-use, except when in timer mode (see
page 12 for details).

REPLACING THE BATTERY
To replace the battery, use a small Phillip’s head screwdriver (or you can
also use a screwdriver found in eyeglass repair kits) and unscrew the two
screws on the base of the unit, located on the back of the calculator. Care-
fully remove the lower back housing, remove the old battery from the clip and
replace it with a new CR-2032 battery. Make sure the positive side (+) is fac-
ing up. Replace the backplate and re-attach the screws.
Note: Replacement CR-2032 batteries are available at most discount or elec-
tronics stores. Or, call Calculated Industries at 1-800-854-8075.
