Fixed point mode selectable switch.
“0”, “1”, “2”, “3”, “4”, “6”, “F”, “A”. (“A”: ADD mode. “F”: full floating mode,
all decimal setting lock key off.)
“IC+” “IC±” item counter mode selectable switch.
“GT” grand total memory selectable switch.
“SET/CAL” tax memory selectable switch. (ON: set mode. OFF: normal
calculation mode.)
Duty of display: Duty = 1/16
Leading zero suppression
Trailing zero suppression
Tax calculation (refer to page 5.): +TAX key is calculation for included tax.
TAX key is calculation for excluded tax.
SET/CAL lock key selects set mode or normal calculation mode.
Changing lock key from set mode to normal calculation mode stores
number of display to tax memory.
Changing lock key from normal calculation mode to set mode recalls tax
rate to display from tax memory.
Depression of +TAX following data key at normal calculation mode
performs the calculating included tax.
Depression of TAX following data key at normal calculation mode
performs the calculating excluded tax.
Electrical Features
P-MOS output buffer with pull down resistor for direct driving of fluorescent display tube.
Oscillator/clock generator internal to chip.
Key board encoding internal to chip.
Shrink dual in line package
Protection
