getting started KEY DEFINITIONS Basic Function Keys +-x *= Arithmetic operation keys. 0-9 and . Keys used for entering numbers O Off Key — Turns all power off, clearing all non-permanent registers. o On/Clear Key — Turns on power. Pressing once clears the display. Pressing twice clears all temporary values. Q Convert Key — Used with the dimensional keys to convert between dimensions or with other keys to access special functions.
QL Memory Clear (M-R/C) — Subtracts the displayed value from Memory. LL Memory Clear — Clears Memory and displays Memory Total. Dimension 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 values (e.g., 6f9i1/2). Repeated presses during conversions toggle between Fractional and Decimal Feet. i Inch Key — Enters or converts to Inches. Entry can be whole or decimal numbers.
m Meters Key — Enters or converts to Meters. c Centimeters Key — Enters or converts to Centimeters. M Millimeters Key — Enters or converts to Millimeters. b Board Feet Key — Enters or converts Cubic values to Board Feet. One Board Foot is equal to 144 Cubic Inches. w Weight Key — Enters or converts (a volume value) to Tons, Pounds, Metric Tons or Kilograms. Repeated presses will cycle through these units.

j Jack Key — Calculates Jack rafter lengths on the Regular-pitched roof side. Qj Irregular Jack — Calculates Jack rafter lengths on the Irregularpitched roof side. P Rake-Wall Key — Finds the stud sizes based on entered Right Triangle values and the stored On-Center spacing. If a dimensional value is entered before pressing P, that value is considered the base and will be added to the stud lengths.

For example, enter 190 mm: 190M. Q9 Tread Width — Stores a desired Tread width other than 10" (default). For example, enter 300 mm: 300M.
Q- Change Sign (+/-) — Toggle displayed value between negative and positive value. Q+ Pi — Displays the value of π (3.1415927). Q> x2 — Squares a linear or nondimensional value. Q. Total Cost — Based on entry of per unit cost. Q0 Store Weight per Volume — Stores a new Weight per Volume value as listed below: Note: After entering a value and pressing Q0 , continue pressing the 0 digit key until you’ve reached the desired Weight per Volume format. To recall your setting, press L0.
Q= Paperless Tape — Useful for checking figures, as it scrolls through your past 20 entries or calculations. Press L= to access Paperless Tape mode. Press + or - to scroll forward or backward. Press = to exit mode and continue with a new entry or calculation. See example below. PAPERLESS TAPE EXAMPLE Add 6 m, 5 m and 4 m, then access the paperless tape mode and scroll back through your entries. Then, back up one entry, exit the tape mode and add 10 Feet to the total.

Battery This model uses one (1) CR2016 battery (included). This should last approximately 800 hours of actual use (1 year plus for most people). Should your calculator display become very dim or erratic, replace the battery. While the calculator is off, turn the calculator over and use a #1 Phillips screwdriver to remove the battery holder screw located near the center at the top. With the screw removed, pull battery holder out, remove old battery, and slide new battery into holder.
