OPERATING CONSIDERATIONS
OPERATING TEMPERATURE
The solid-state devices in the Calculator are designed to operate normally at
;emperatures between 0 and 60 degrees Centigrade (32 to 120 degrees
-ahrenheit). If you operate the Calculator in temperatures outside of this range,
/ou may encounter inaccurate operation,
NEGATIVE NUMBERS
Negative numbers can be used in any calculations. To establish a negative
lumber, push the {—) key immediately after you enter the number.
DECIMAL PLACES
The Calculator has a floating decimal point. It is necessary to push the
DECIMAL {*) key in proper sequence to enter the decimal point in the entry,

14206.6506^-NOT SHOWN
8-DIGIT DISPLAY
Note that the last digit shown is not rounded off to indicate the value of the part
of the answer which is beyond the readout capacity of the Calculator.
The floating DECIMAL POINT gives only the most significant digit (within the
8'digit capacity of the Calculator} to the right of the decimal point as shown*
Since "5" is the fast significant digit in the answer to the addition above, the
answer displayed would be 14206.65,
A characteristic of the Calculator is that any fractional number is always
preceded by 0 (zero) ora whole number. Thischaracteristjc limits the input and
readout capacity of the Calculator to seven digits to the right of the decimal
point. The Calculator, however, can handle up to 14 places In multiplying and
dividing fractional numbers.
OVERRANGE
The overrange indicator at the left end of the display will tight (Ef when the
whole-number entered, or (a) if the final answer in a calculation, is beyond the
8-digit capacity of the Calculator. In an overrange condition, the part of the
answer shown will be correct, but the decimal point will be eight places to the
left of its correct location and the part of the answer beyond eight digits will not
be shown. The presence of the (E) does not prevent further calculations
although it would hide the presence of a minus sign.
The presence of the (o) does prevent further entry and only
pressing the (C) kev
will restore the Calculator for further calculations.
