• Description: Single-chip Cmos Lsi For Calculators With Printers
• Manufacturer: TOSHIBA Semiconductor CORPORATION

[D%] ...................... If a multiplication/division instruction is memorized, cancels the data.
[+/-]....................... 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
[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
[C] ......................... Cancels all arithmetic instructions and errors, clears the contents of all the
[CE] ...................... If pressed at key entry, clears only the contents of the display; does not change the
[C/CE]................... If pressed at key entry, operates same as the [CE] key.
[#/P] ...................... If pressed after the numerical key entry, prints the contents of the key entry data
[ON (1)] ............... If pressed in HOLD mode, cancels HOLD. At that time, cancels all arithmetic
[ON (2)] ............... If pressed in lower frequency (32.768 KHz for CLOCK) operation mode, drives
[OFF] ................... Forcibly enters HOLD mode or lower frequency (32.768 kHz for CLOCK) mode.
[­] ........................ Feeds paper.
D%key operation example:
estimation calculation error, cancels the error.
GT memory, but does not change current state. If the key is pressed twice, calls
the contents of GT memory and clears them.
registers except the memory register, and prints 0.C.
stored arithmetic instruction or the contents of the data register. Invalid if pressed
after one of the following keys: [C] [´] [¸] [+] [-] [=] [%] [D%] [M+] [M-] [M¹] [M*]
[M*¹] [MU/D] [IC].
The result of pressing the [CE] key after the [#/P] key depends on the state before
the keys were pressed.
If pressed after one of the following keys, operates same as the [C] key: [C/CE] [´]
[¸] [+] [-] [=] [%] [D%] [M+] [M-] [M¹] [M*] [M*¹] [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.
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.
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.
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.
