i - Inch Key
Enters or converts to Inches. Entry
can be whole or decimal number.
Also used with the / key for entering
Fractional Inch values (e.g., 9i
1 / 2 ). Repeated presses during
conversions toggle 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).
m - Meter Key
Enters or converts to Meters.
Convert Key Functions
Ç - Convert Key
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 x - Clear All
Clears all stored values and sets calculator back to defaults.
Ç / - Percent (%)
Four-function (+, -, x, ÷) percent.
POCKET REFERENCE GUIDE - 3
Ç – - Change Sign (+ / -)
Toggles displayed value to positive or
negative. (Repetitive presses of Ç
– will change sign from positive or
negative.)
Ç ÷ - Square Root
Finds Square Root of value in display.
Ç + - x
2
Finds Square of value in display.
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
m subtracts 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.

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 o to exit.

for deck or fence calculations. To recall
this setting, press r d. Also used
to store the board On-center for Fence
Spacing. Default is 5-11/16 Inches.
F - Fence
Multi-function key that finds the
number of fence boards, number of
posts and number of rails based on
an entered distance, Board
Width/O.C. and post spacing.
