AUTO SHUT-OFF, BATTERIES, RESET

ACCURACY/ERRORS

Accuracy/Display Capacity — Your calculator has a twelve-digit
display made up of eight digits (normal display) and four fractional
digits. You may enter or calculate values up to 19,999,999.99. Each
calculation is carried out internally to ten digits.
Errors — When an incorrect entry is made, or the answer is beyond
the range of the calculator, it will display the word "ERROR." To clear
an error condition you must hit the o button once. At this point
you must determine what caused the error and re-key the problem.

None
Auto-Range — If an "overflow" is created because of an input and
calculation with small units that are out of the standard seven-digit
range of the display, the answer will be automatically expressed in
the next larger units (instead of showing "ERROR") — e.g.,
10,000,000 mm is shown as 10,000 m. Also applies to inches, feet
and yards.
Note: If Exponential Notation is activated through the Preference Setting, the value
will be shown in scientific notation (e.g., 10 million mm—1.000007 mm).

AUTO SHUT-OFF

Your calculator is designed to shut itself off after about 8-12 minutes
of non-use.
