- Press the RESET switch located on the back of the unit. (See RESETTING THE UNIT.)
The clock starts, indicating the current date and time as January 1, 2008, 12:00:00 a.m.
Adjusting date and time
Example: When the date is September 15, 2007, and the time is 3:38 p.m.
When the adjustment is complete, the clock starts at 3:38:00 p.m.
Operating Control
POWER SWITCH; PRINT / ITEM COUNT MODE SELECTOR:
- Power Off
- Power ON. Set to the non-print mode.
- Power ON. Set to the print mode.
- Power ON. Set to the print and item count mode.
For addition or subtraction, each time the (+) is pressed, 1 is added to the item counter, and each time the (-) is pressed, 1 is subtracted.
- The count is printed when the calculated result is obtained.
- Pressing of (×), (C/CE) (C/CE) clears the counter.
When the grand total/rate setting mode selector is in the ON position (GT), the counter will count the number of times that the calculation results have been stored in the grand total memory. To print and clear the count, press the (GT) key.
The memory item counter will count the number of times that the (M+) key has been pressed in the addition.
Note:
- Each time the (M-) key is used in the subtraction, 1 will be subtracted from the count.
- The count is printed when the memory is recalled.
- Pressing the (*M) key clears the counter.
ROUNDING SELECTOR:
Example: Set Decimal Selector to 2.
4 ÷ 9 = 0.444 …, 5 ÷ 9 = 0.555…
Note: The decimal point floats during successive calculations by the use of (×) or (÷).
If the decimal selector is set to “F,” then the answer is always rounded down.
DECIMAL / ADD MODE SELECTOR:
- “3 2 0”: Presets the number of decimal places in the answer.
- “F”: The answer is displayed in the floating decimal system.
- “A”: The decimal point in addition and subtraction entries is automatically positioned to the 2nd digit from the lowest digit of the entry number. Use of the add mode permits addition and subtraction of numbers without entry of the decimal point.
Use of (•), (×), and (÷) will automatically override the add mode, and decimal correct answers will be printed.
Overview of Keys
CLOCK / CALENDAR KEY:
- Each time this key is pressed, the mode switches.
Calculation mode→Date display mode→Clock display mode→Calculation mode

- The intermediate result of an addition or subtraction in the Change calculation is retained.
- While the POWER SWITCH / PRINT / ITEM COUNT MODE SELECTOR is placed in “P” or “P•IC”, the pay amount is printed after “• • • • • • • • • • • • •” and the change is printed with “CG”.
Note: The displayed change value will not be added to the grand total memory.
INK ROLLER REPLACEMENT
If printing is blurry even when the ink roller is in the proper position, replace the roller.
Ink roller: IR40T
WARNING: APPLYING INK TO A WORN INK ROLLER OR USE OF UNAPPROVED INK ROLLER MAY CAUSE SERIOUS DAMAGE TO THE PRINTER.
- Set the power switch to OFF.
- Remove the printer cover. (Fig. 1)
