Used with the dimensional unit keys
to convert between dimensions, the
Project Keys to calculate material
quantities, or with other keys to
access special functions.

Ç s - Pi (π)
Constant 3.141593.
Memory
s m (M+) - Adds or stores a value
in the semi-permanent memory (e.g.,
1 5 0 s m). Semi-permanent
means the value is cleared when the
calculator is turned off.
Ç – s m (M-) - Subtracts a
value from the semi-permanent
Memory (e.g., 1 5 0 Ç – s
msubtracts 150 from the memory).
r m (M-R/C) - Recalls Memory value
(e.g., if 150 has been stored in Memory,
pressing r m will display 150).
r r - Displays and clears Memory
value.
POCKET REFERENCE GUIDE - 4
Entering Square or Cubic
To label a dimension as “Square” or
“Cubic,” enter the value, then press the
desired dimension key twice for
Square and three times for Cubic. For
example, to enter 25 Cubic Yards,
press 2 5 y y y.
Fraction Resolution
Your calculator is set to display Fractional
values to the nearest 16th of an Inch
(default setting). Press r / to access
the fraction resolution setting. Repeated
presses of /will then revolve through
the available settings: 1/16, 1/32, 1/64,
1/2, 1/4 and 1/8. Press oto exit.
Project Keys
p- Paint
Calculates volume of paint, based on
an entered area and a stored Paint
Coverage per Gallon (see below).
Finds quantity in Gallons, Quarts or
Pints upon repeated presses.
s p - Stores Paint Coverage
Stores Paint Coverage per Gallon. To
recall this setting, press r p.
Default is 350 sq.ft. per gallon.
POCKET REFERENCE GUIDE - 5
w- Wallpaper
Calculates number of rolls of wallpaper,
based on an entered area and a stored
Wallpaper Roll Coverage Area (see
below).
s w - Stores Wallpaper Roll
Coverage Area

Feet) per Wall-paper Roll. To recall
this setting, press r w. Default
is 56 Square Feet per roll.
t - Tile
Finds the number of tiles, based on
an entered area and a user-stored
Grout Width (see below). Repeated
presses will scroll between numbers
of tiles for various “standard” tile
sizes (18”, 16”, 13”, 12”, 10”, 8”, 6”,
4”, 2”, 1” and 24”).
Note: Tile sizes shown in Inches, not Square
Inches (as used in custom tile size calculations).
In other words, a 6” tile is really 6” x 6”, or a 36
Square-Inch tile, but it is labeled as a 6” size.
s t - Stores Grout Width
Stores Grout Width in Inches; used in
calculating the number of tiles (see
above). To recall this setting, press
