Pressing once clears the display. Pressing twice clears all temporary values. O Off ─ turns all power off, clearing all non-permanent registers. + – x ÷ = Arithmetic operation keys. 0 – 9 and • Digits used for keying in numbers. % Percent (%) ─ four-function (+, -, x, ÷) percent. Dimensional Unit Keys y Yards Key ─ enters or converts to yards. f Feet Key ─ enters or converts to feet as whole or decimal numbers. Also used with the i and / keys for entering feet-inch-fraction values (for example, 6 f 9 i 1 / 2). Repeated presses during conversions toggle between feet-inch-fractions and decimal feet. (cont'd)

inches. Entry can be whole or decimal number. Also used with the / key for entering fractional inch values (for example, 9 i 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 – Change Sign (+/-) ─ toggles displayed value to positive or negative. (cont'd) Ç ÷ Ç x Ç % Memo Ç + Ç – Ç + Ç = Ç o

to ecimal key for for eated gle nter red as per s to the onvert h other nctions. gles e or Ç ÷ Square Root (√¯x) ─ finds square root of value in display. Ç x Value Squared (x2) ─ finds square of value in display. Ç % Pi (π) ─ constant 3.141593. Memory Ç + M+ ─ adds or stores a value in the semi-permanent memory (for example, 1 5 0 Ç +). Semi-permanent means the value is cleared when the calculator is turned off. Ç – Ç + M- ─ subtracts a value from the semi-permanent memory (for example, 1 5 0 Ç – Ç + subtracts 150 from the memory). Ç = MR ─ recalls memory value (for example, if 150 has been stored in memory, pressing Ç = will display 150). Ç o MC ─ clears memory value.

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. Fractional Resolution Your calculator is set to display fractional values to the nearest 16th of an inch (default setting). Press Ç / to access the fractional resolution setting. Repeated presses of / then revolve through the available settings: 1/16, 1/32, 1/64, 1/2, 1/4, and 1/8. Press o to exit. Project Keys p Paint ─ calculates volume of paint, based on an entered or calculated area. Finds quantity in gallons, quarts, or pints with repeated presses. w Wallpaper ─ calculates number of rolls of wallpaper, based on an entered or calculated area. t c C Ç •

Repeated presses scroll between numbers of tiles for various standard tile sizes (18″, 16″, 13″, 12″, 10″, 8″, 6″, 4″, 2″, 1″, and 24″). Tile sizes are shown in inches, not square inches. 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. c Carpet ─ calculates carpet length required, based on entered or calculated area. Repeated presses of c scroll between values for 12′, 13′, and 15′ rolls. C Concrete ─ calculates the number of bags of concrete required, based on an entered or calculated volume (for example, cubic feet or cubic yards). Ç • Cost ─ allows you to calculate total material cost.
