KEY DEFINITIONS
Basic Function Keys
+-x Arithmetic operation keys.
÷=
%Four-function (+, –, x, ÷)
percent key.
0– 9Keys used for entering
and •numbers.
OOff Key — Turns all power
off, clearing all non-perma-
nent registers.
oOn/Clear Key — Turns on
power. Pressing once clears
the display. Pressing twice
clears all temporary values.
ÇConvert Key — Used with
the dimensional keys to
convert between dimen-
sions or with other keys to
access special functions.
SStore Key — Used for stor-
ing values.
®Recall Key — Recalls
stored values.

POCKET REFERENCE GUIDE — 2
Unit Keys
yYards Key — Enters or
converts to Yards.
fFeet Key — Enters or con-
verts to Feet as whole or
decimal numbers. Also
used with the iand /
keys for entering Feet-Inch
values (e.g., 6f9
i1/2). Repeated
presses during conversions
toggle between Fractional
and Decimal Feet.
iInch Key — Enters or con-
verts to Inches. Entry can
be whole or decimal num-
bers. Also used with the /
key for entering fractional
Inch values (e.g., 9i
1/2). Repeated press-
es during conversions tog-
gle between Fractional and
Decimal Inches.
/Fraction Bar Key — Used
to enter Fractions. Fractions
can be entered as proper
(1/2, 1/8, 1/16) or improper
(3/2, 9/8). If the denomina-
tor (bottom) is not entered,
the calculator's fractional
accuracy setting is auto-
matically used.
mMeters Key — Enters or
converts to Meters.
POCKET REFERENCE GUIDE — 3
Ç7 Centimeters (cm) — Enters
or converts to Centimeters.
Ç9 Millimeters (mm) — Enters
or converts to Millimeters.
Ç2 Acres (Acre) — Enters or
converts to Acres.
Length, Width and Height Keys
lEnters Length for calculation
of Area or Volume.
WEnters Width and calculates
Area, Square-up and
perimeter.
hEnters Height and calculates
Volume, wall Area and total
room Area. Calculates Height
(Depth) based on entered
Width and Slope or Percent
Grade. This is a permanent
entry; stored value holds
when turned off.
Construction Project Keys
ÍSlope — Enters or calcu-
lates a slope ratio or slope
angle. Calculates based on
entered Width and Height
(Depth).
ÇÍ Percent Grade (%Grade) —
Used to enter or solve Percent
Grade. Calculates Percent
Grade based on entered
Width and Height (Depth) or
Slope.
POCKET REFERENCE GUIDE — 4
sSquare-Up Key —
Calculates the “Square-up”
(diagonal) Length given
entered Length and Width
values.
dDrop Key — Calculates
total drop (or fall) over an
entered Length given
entered percentage drop,
Inch per Foot drop, or
degrees of drop. Continued
presses will act as a “con-
stant add,” for displaying
successive drops.
Excavation/Volume Keys
¬Loads Key — Calculates
number of loads for a given
Volume or Length, Width,
and Height (Depth) values
and stored load size.
S¬ Load Size — Stores load
size. Load size must be
entered as a cubic value
(e.g., 8yyy
S¬). The default size
is 8 cubic Yards.
FCut/Fill Key — Used to
enter or calculate the cut or
fill amount. Based on entries
of proposed and existing
benchmarks. A fill is dis-
played as a positive value; a
cut as a negative value.
POCKET REFERENCE GUIDE — 5
eExisting Key — Used to
enter or calculate an existing
benchmark, Grade or value.
pProposed Key — Used to
enter or calculate a proposed
benchmark, Grade or value.
bBank Volume Key —
Enters or calculates the
Volume for bank fill material.
Bank fill is material in an
untouched, pristine state.
çCompacted Volume Key —
Enters or calculates the
Volume for compacted fill
material. Compacted fill is
material that has been com-
pacted.
Çç Percent Shrink (%Shrink)
— Enters or recalls percent
shrink factor for converting
between bank and com-
pacted fill Volumes. Default
is 5%.
LLoose Volume Key —
Enters or calculates the
Volume for loose fill material.
Loose fill is material that has
been disturbed or excavated.
ÇL Percent Swell (%Swell) —
Enters or recalls the percent
swell factor used for con-
verting between bank and
loose Volumes. Default is
10%.

Miscellaneous Functions
aBackspace Key.
Ça ( ) Square Root.
®= Paperless Tape.
ÇS Preference Settings.
Ç÷ (1/x) Reciprocal — Finds
the reciprocal of a number
(e.g., 8Ç÷0.125).
Çx Clear All — Returns all
stored values to the default
settings. (Does not affect
Preference Settings.)
Ç- (+/–) Toggle.
Ç+ Pi (π) 3.141593.
Ç• Converts between D:M:S
and decimal degrees.
Ç% x2— Squares the value in
the display.
Ç/ Exponential Notation (x10y).
Ç0 Total Cost (based on entry
of per unit cost).
S0 Weight per Volume –
Stores a new Weight per
Volume value.
Note: After entering a value and pressing S0,
continue pressing the 0digit key until you’ve
reached the desired Weight per Volume format.
To recall your setting, press ®0.
