Kinds of lock key: “NP” printing mode selectable switch.
“Σ” summation mode selectable switch.
“5/4” “CUT” “UP” rounding switch.
Fixed point mode selectable switch.
“0”, “1”, “2”, “3”, “4”, “6”, “F”, “A”.
“IC+” item counter mode selectable switch.
“GT” grand total memory selectable switch.
“SET”, “CAL” tax memory selectable switch.
Duty of display: Duty = 1/17.77
Leading zero suppression
Trailing zero suppression
Tax calculation: +TAX key is calculation for included tax.
TAX key is calculation for excluded tax.
SET selects set mode for tax rate.
CAL selects normal calculation mode.
Changing lock key from SET to CAL stores number of display to tax memory.
Changing lock key from CAL to SET recalls tax rate to display from tax memory.
Depression of +TAX following data key at CAL mode performs the calculating included
tax.
Depression of TAX following data key at CAL 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.
Dual in line package.
