Battery And Auto-Shut-Off; Full Reset, All-Clear - Calculated Industries Construction Master III User Manual

Fractional Display — Two digits are al-
lowed for the numerator and another two
for the denominator. The largest proper
fraction allowed would be 99/99. The cal-
culator will also handle improper fractions
i.e., 24/16. Once an operation takes place,
the improper fraction is divided out and is
reduced to its lowest form. Any fraction may
be entered as above. However, once a
problem is entered and operated upon, the
fraction will be rounded and displayed to the
nearest 1/64.
BATTERY & AUTO SHUT-OFF
Your calculator is powered by a single 3-Volt
Lithium CR-2032 battery. This should last up-
wards of 800 hours of actual use (1 year plus for
most people). Should the display become very
weak or erratic, replace the battery.*
Your calculator is designed to shut itself off
after about 8-12 minutes of non-use. Note:
Values in Memory or shown on the display will
be cleared.

FULL RESET, ALL-CLEAR

Your calculator is equipped with a special
two-key sequence — [Conv] [x] — to clear all
memory registers to their initial default values.
EXTREME CAUTION SHOULD BE USED AS
ALL STORED VALUES WILL BE ALTERED.
