Keys in numbers from 0 to 9, 00, and 000. If the number of display digits exceeds [00, 000] 10, 12 or 14, key entry is invalid. [･].......................... If this key is pressed after a key operation except data entry, the display is cleared and entry of [･] is stored in memory. The decimal point is shifted for subsequent data entry. If the [･] key is pressed during data entry, display does not change. [+, -]...................... Add or subtract operation data and display the result. The decimal point is floating except when A mode is specified. Addition or subtraction can be performed repeatedly. If these key are pressed in multiplication/division mode or in constant calculation mode, add or subtract display data to addition/subtraction registers, then display the result. At this time, in the operation mode multiplicand or divisor do not change. These keys increment or decrement the item counter. In the following operation mode, the operations are executed, and the results are printed and displayed. At that time, addition or subtraction using the addition/subtraction register is not executed. 1) Percent discount/add-on calculation a ´ b% + .....a + (ab/100) c% +......a + (ac/100) a ´ b% - .....a - (ab/100) c% -......a - (ac/100) Percent discount/add-on with constants are calculated as above. [◊].......................... Prints and displays the intermediate result in addition/subtraction register. In item count mode, prints the contents of the item counter before the calculation result printing. Contents of data register or stored arithmetic instruction are not changed. [*].......................... Prints and displays the result in addition/subtraction register. Automatically feeds paper one line. In item count mode, the contents of the item counter are printed before the calculation result printing. After this key operation, the contents of the addition/subtraction register are cleared. The contents of the item counter are cleared at the first addition/subtraction in next step. The contents of the data register or stored arithmetic instruction are not changed. When GT mode is specified, the result of addition/subtraction is added to the GT memory. [M+, M-] ............. If the arithmetic instruction is not stored or if the mode is constant calculation mode, first prints the display contents after rounding to the specified number of decimal places, performs addition/subtraction using the data in memory, then stores the result in memory. If the multiplication/division instruction is stored, executes the arithmetic instruction, rounds the result to the specified number of decimal places, prints and display the result, adds/subtracts with the data in memory, then stores the result to memory. At that time, the multiplicand or divisor is stored together with the mode, constant calculation mode. When this key is pressed immediately after the [´] or [M+, M-] key, operation is the same as that for the [=] key; that is, adds/subtracts using data in memory. This key operation increments or decrements the item counter for memory. [M◊] ...................... Prints or displays the intermediate result of memory calculation. In item count mode, prints the contents of the item counter for memory before the calculation result printing. Contents of the data register or stored arithmetic instruction are not changed. 8 2003-03-24 TC83230-0021/JTC83230-0021S [M*] ...................... Prints and displays the result of memory calculation and automatically feeds paper one line. In item count mode, prints the contents of the item counter for memory before the calculation result printing. After the [M*] key operation, the contents of memory and the contents of the item counter for memory are cleared. Contents of the data register or stored arithmetic instruction are not changed. [M*◊]..................... Operates both [M◊] and [M*] key operations. Pressing this key once is equivalent to pressing the [M◊] key; pressing the key twice is the same as pressing the [M*] key. [´, ¸]...................... If the multiplication or division instruction is stored in memory, prints the operators, performs the operations and displays the results while simultaneously storing a new arithmetic instruction in memory. The decimal point for the result is floating. If the [´] or [¸] key is pressed in constant calculation mode, prints the displayed numeric value without performing an operation and stores a new multiplication/division instruction in memory. [=].......................... Executes a stored multiplication/division instruction, rounds the result to the specified number of decimal places, prints and displays the result, then automatically feeds the paper one line. Stores the multiplicand or divisor together with constant calculation mode in memory. If an instruction is not stored in memory, no operation is performed and the previous state is held. Pressing the [=] key immediately after the [´] or [¸] key performs the following operation. a ´ =.......aa a ¸ =.......1 [%]......................... If an arithmetic instruction is stored in memory, performs percentage calculation, rounds the result to the specified number of decimal places, prints and displays the result. Stores the multiplicand/divisor together with constant calculation mode in memory. If a percentage calculation for multiplication is performed, percent discount/add-on calculation can be done by using the [+] or [-] key. At that time, addition/subtraction using the addition/subtraction register is not performed. If an arithmetic instruction is not stored in memory, no operation is performed and the previous state is held. Pressing the [%] key immediately after the [´] or [¸] key performs the following operation. a ´ % = ...aa/100 a ¸ % = ...100 % key operation example: percent discount/add-on calculation a ´ b%....ab/100 +.............a + (ab/100) c% ..........ac/100 +.............a + (ac/100) a ´ b%....ab/100 -.............a - (ab/100) c% ..........ac/100 -.............a - (ac/100) [MU/D].................. If a multiplication/division instruction is stored in memory, cancels the data. The decimal point for the result is floating. MU/D key operation example: aMU/Db =................. a/(1 - (b/100)) - a (prints profit) a/(1 - (b/100)) (mark-up) c =................. a/(1 - (c/100)) - a (prints profit) a/(1 - (c/100)) (mark-up) aMU/Db +/- =........... a/(1 + (b/100)) - a (prints profit) a/(1 + (b/100)) (mark-down) c +/- =........... a/(1 + (c/100)) - a (prints profit) a/(1 + (c/100)) (mark-down) 9 2003-03-24 TC83230-0021/JTC83230-0021S [D%] ...................... If a multiplication/division instruction is memorized, cancels the data. D%key operation example: aD% b =..................... b - a (b - a)/ïaï (prints difference) c = ..................... c - a (change delta percent) (c - a)/ïaï (prints difference) aD% b +/- =............... -(b + a) (change delta percent) -(b + a)/ïaï (prints difference) c +/- = ............... -(c + a) (change delta percent) -(c + a)/ïaï (prints difference) [+/-]....................... Inverts sign of the displayed number at key entry. [®] ........................ Shifts the contents of the display to the right by one digit at key entry. For an estimation calculation error, cancels the error. [IC]........................ Calls the contents of the item counter. Does not change current state. [GT] ...................... Calls the contents of GT memory. If the key is pressed once, calls the contents of GT memory, but does not change current state. If the key is pressed twice, calls the contents of GT memory and clears them. [C] ......................... Cancels all arithmetic instructions and errors, clears the contents of all the registers except the memory register, and prints 0.C. [CE] ...................... If pressed at key entry, clears only the contents of the display; does not change the stored arithmetic instruction or the contents of the data register. Invalid if pressed after one of the following keys: [C] [´] [¸] [+] [-] [=] [%] [D%] [M+] [M-] [M◊] [M*] [M*◊] [MU/D] [IC]. The result of pressing the [CE] key after the [#/P] key depends on the state before the keys were pressed. [C/CE]................... If pressed at key entry, operates same as the [CE] key. If pressed after one of the following keys, operates same as the [C] key: [C/CE] [´] [¸] [+] [-] [=] [%] [D%] [M+] [M-] [M◊] [M*] [M*◊] [MU/D] [IC]. The result of pressing the [C/CE] key after the [+/-] or the [#/P] key depends on the state before the keys were pressed. [#/P] ...................... If pressed after the numerical key entry, prints the contents of the key entry data register together with the # symbol, but does not change the current state. If the key is pressed after a key except the numerical keys or [+/-] key, does not change the contents of the displays or the current state. If the key is pressed in clock mode, automatically prints the displayed date and time. [ON (1)] ............... If pressed in HOLD mode, cancels HOLD. At that time, cancels all arithmetic instructions and errors. The contents of the memory register and the TAX RATE before HOLD mode are retained; all other registers are cleared. While the [ON (1)] key is pressed, the [OFF] key is invalid. [ON (2)] ............... If pressed in lower frequency (32.768 KHz for CLOCK) operation mode, drives higher frequency (4 MHz) operation mode (normal calculation mode). At the same time, cancels all arithmetic instructions and errors. The contents of memory register and TAX are retained before [OFF] key; all other registers are cleared. While the [ON (2)] key is invalid. [OFF] ................... Forcibly enters HOLD mode or lower frequency (32.768 kHz for CLOCK) mode. [] ........................ Feeds paper. 10 2003-03-24 TC83230-0021/JTC83230-0021S [P/NP] ................... Switches between PRINT and NON-PRINT mode. At reset, NON-PRINT mode is set.

Example of [A ® B] key operation when rate value is 130: a [A ® B].................. a130 Pressing the < [A ® B] key after clearing display calls the rate value. < [B ® A] ................. When the [TIME] key is on, moves the cursor to the left as the [<] key. When the [CAL] key is on, executes rate conversion as [B ® A] key. Example of [B ® A] key operation when rate value is 130: a [B ® A].................. a/130 Pressing the < [B ® A] key after clearing display calls the rate value. 11 2003-03-24 TC83230-0021/JTC83230-0021S (3) Explanation of lock keys [0, 1, 2, 3].............. Sets the specified decimal point. If no specification, floating is set. [4, 6, A] When processing floating point data, the operation result is zero-shifted. When A mode is specified, key-entered data are multiplied by 1/100 only when the key-entered numerical value is used for addition/subtraction or memory addition/subtraction. If the [･] key is pressed during data entry, A mode is invalid. The operation result is treated the same as the specified decimal point, 2. [CUT, UP] ............ Rounds-off in CUT mode; rounds-up in UP mode; when no specification is made, half-adjusts. When a decimal point is specified, the digit (s) in the subsequent decimal place is (are) half-adjusted, rounded-off, or rounded-up (??). If floating point is specified, the value of the least significant digits which cannot be displayed is rounded off. [NP] ...................... Switches between print and non print mode. In non-print mode, disables all printing except [] or [#/P] key. When mode changes from non-print to print, feeds the paper one line. [IC+]...................... Selects item count mode. [IC±] IC+ ......... Counts up by the [+] or [-] key. IC±.........Counts up by the [+] key, down by the [-] key. [S] .........................

Valid when the [14] lock key is off; selects 10 digits display and printer when the [ 10/12 ] lock key is on; selects 12 digits display and printer when the [ 10/12 ] lock key is off. [ CLOCK ] ............. When [ CLOCK ] lock key is off, CLOCK function is operatable. In this case, [ON (2)] and [OFF] keys are available for ON/OFF function. When [ CLOCK ] lock key is on, CLOCK function is not operatable. In this case, [ON (1)] and [OFF] keys are available for ON/OFF function. 12 2003-03-24 TC83230-0021/JTC83230-0021S Explanation of Functions (1) Auto power-off function When the [TMR] lock key is on and there is no key input for 10 minutes, automatically enters HOLD state. The [ON] key is used to cancel HOLD mode or to drive higher frequency (4 MHz) mode. When power is turned on by the [ON] key, cancels all arithmetic instructions and errors, stores states before power off in memory and GT memory, and clears all other contents in the RAM. If any key is pressed within 10 minutes, the automatic power-off timer is cleared and resumes counting. Auto power-off functions even though a lock key is kept being pressed (under off-chatter). (2) Clock function Time is input and displayed using a 24-hour clock. In clock display mode, a hyphen “-” between hours and minutes blink. In date display, a hyphen “-” between month and day does not blink. To set or change the time or date, use the [TIME] key to enter clock/date setting mode. CLOCK function is only available when [ CLOCK ] lock key is off. 1) How to set or change time and date a) Enter clock display mode using the [TIME] key. (the current time is displayed.) b) Press the [TM･S] key to set to clock/date setting mode. (year and data setting when the [TM･S] key is pressed the first time.) At that time, the cursor blinks at the year. In clock/date setting mode, the display is not zero-suppressed. c) Move the cursor using the cursor keys to the position where the data are to be changed. Input the year, month, day, hour, or minute to be changed using numeric data keys. After a numeral is input, the cursor automatically moves to the next position. d) After inputting the year and date, pressing the [TM･S] key a second time ends date setting and clock setting mode is entered. Input numerals for time the same way as year or date. e) Pressing the [TM･S] key a third time sets the hours and minutes, then returns to clock display mode. 2) Clock/date input error If a value which does not exist is specified for the month, day, hour, or minute, a clock/date setting error occurs. When an error occurs, the cursor returns to the beginning of the position where the error occurred and the system stands by for fresh input. The error mark is not displayed on LCD. 3) Clear or mode key operation during clock/date setting Pressing the [C] or [C/CE] key cancels clock/date setting mode and returns to clock display mode. While clock function is operative, the [OFF] or auto power-off function cannot be used. 4) Initial values at reset 01 01-01 (YY MM/DD), 00: 00: 00 (HH: MM: SS) 13 2003-03-24 TC83230-0021/JTC83230-0021S 5) Setting example 1: to set data, 15: 34 July 10’93, a) Press the [TIME] key (12-digit display) 0 b) e) f) g) 0 Clock display mode 1 0 1 - 0 1 Inverted display represents blinking. 3 0 7 - 1 0 Press the [TM･S] key. 0 0 - 0 0 1 5 - 3 4 1 5 - 3 4 5 - 3 4 Press the [1], [5], [3], and [4] keys.
