1/ NOMENCLATURE Power switch: . Move the switch forward to activate the calculator. I 0·1 Read-out: Shows each entry and result through a Digitron tube panel. suppressing unnecessary 0'8 (zeros}. c:J Numeral/Decimal point keys: Enter numerals. For decimal places, use thec:Jkey in its logical sequence. ill-en D, CI, ~, =, BFunction command/Result keys: Perform the four basic calculations when these keys are pressed in formula sequence.
B< 8) Memory plus (minus) key: Transfers the number displayed to the memory positively (negatively). Obtains answer in four functions and automatically accumulates it into the memory positively (negatively). ~Memory recall key: Recalls the contents of the memory without clearing. OOPercent key: Performs percentage calculations, including add-ons, discounts and markups. tOSquare root key: Extracts the square root ofthenumber displayed. BClearkey: Clears entry for correction. .
rJ3AIl clear key: Clears the entire machine including the memory, and releases overflow or error check. r2..., F CUT 5/4 I .. I Decimal mode selector: At the "F" position, the decimal floats and the underflow system works to protect the significant digits. At the "CUT" position, an answer is automatically cut off at 2 decimal places, applying floating mode for entry and intermediate result. At the "5/4" position, an answer is rounded off in the same way as above.
DRY BATTERY OPERATION Two AA size manganese dry batteries (UM-31 give approximately 8 hours continuous operation (16 hours on type SUM-31. When battery power decreases, the whole display darkens.
