KEY DEFINITIONS
Basic Operation Keys
o On/Clear — Turns power on. Pressing once clears
the display. Pressing twice clears all temporary
values.
OTurns all power off, clearing all non-permanent
registers.
+ – x Arithmetic operation keys.
÷ =
%Four-function (+, -, x, ÷) percent key. (See page 33
for examples.)
0– 9and •Keys used for entering digits.
)(DESKTOP ONLY)Enters “00” to save keystrokes (e.g.,
1 ) to enter 100).
B Backspace Key — Used to delete entries one key-
stroke at a time (unlike the ofunction, which
deletes the entire entry).
Convert ÇKey — Unit Conversions and Second Functions
The Çkey is to convert between measurement units or to access
the second functions listed below:
Ç x Clear All — Clears all values, including Memory.
Resets all permanent entries to default values
(except Preference Settings which are retained).
Note: Use only when necessary, as it resets all stored values to
factory defaults. See page 88 for a listing of default values.
Ç % x2 — Squares the value in the display. For example,
to square the value 10, enter 1 0 then Ç %.
Ç B Square Root Function ( ) — Used to find the
square root of a non-dimensional or area value
(e.g., 1 0 0 Ç B = 10).
Ç / x10y — Allows entry of an exponent. For example,
8 Ç / 1 4 is 8 times 10 to the 14th power.

U SER ’ S G UIDE — 9
Ç ÷ 1/x — Finds the reciprocal of a number (e.g., 8
Ç ÷ = 0.125).
Ç – Change Sign (+/–) — Toggles the sign of the dis-
played value to positive or negative.
Ç + Pi ( π ) — Constant = 3.141593
Ç • Degrees:Minutes:Seconds — Converts between
D:M:S and decimal degree formats.
Ç 0 Total Cost — Calculates total material cost given a
unit dimension and an entered Per Unit Cost.
Ç ß Access Preference Settings — Used to access
various customizable settings, such as dimensional
answer formats (see Preference Settings on page
89).
Memory and Storage Functions
Your calculator has two types of Memory:
1) basic memory or semi-permanent, cumulative µ;
2) non-cumulative Storage Registers (M1-M3).
µ Semi-Permanent Memory — Adds any displayed
number, dimensioned or unitless, to the semi-per-
manent, cumulative Memory. Values can be sub-
tracted from this Memory using Ç µ (M–) . ®
µwill display the value in the Memory. ® ®
will display and clear the value in the Memory. Ç
®will clear the cumulative Memory without dis-
turbing the existing display.
ß 1 – 3 Storage Registers (M1) through (M3) — Stores
the displayed value in non-cumulative, permanent
Memory (e.g., 1 0 ß 1). Good for storing a
single value, for future reference (® 1 = 10).
Note: Non-cumulative means it only accepts one value (does not
add or subtract) and a second entered value will replace the first.
Permanent means the value is stored even after the calculator is
shut off. To delete a stored value, enter a new value or perform a
Clear All Ç x .
