ON, OFF keys
1)
In touch key mode
Pressing the [OFF] key enters HOLD mode.
When entered in HOLD mode by the [OFF] key or the auto power off function, pressing the
[ON/C or ON/C, CE] key cancels HOLD mode.
When HOLD mode is canceled, the memory, TAX, and GT registers are retained. Clears
everything else, prints 0.*, then feeds the paper one line.
2)
In lock key mode
Setting the lock keys to off enters HOLD mode; to on, cancels HOLD mode.
When HOLD mode is entered by the auto power off function, turning the lock keys to off, then
on, cancels HOLD mode.
When HOLD mode is canceled, the memory, TAX, and GT registers are retained. Clears
everything else, prints 0.*, then feeds the paper one line.
(5)
Optional switch
The following optional switches are detected immediately after reset only.
1)
[TMR]
When this key is on, the auto power off function operates for about six minutes.
2)
[T/L]
When the key is on, touch key mode is entered; when off, lock key mode.
3)
[2 M]
Specifies the number of memory registers.
When the key is on, one memory register is selected; when off, two memory registers.
4)
[2 TAX]
Specifies the number of TAX registers.
When the key is on, a TAX register is selected; when off, two TAX registers.
5)
[ON/C or ON/C, CE]
Specifies the function added to the ON key: [C] or [C/CE].
(6)
Operations
1)
Operation method
Operates according to formulas.
The number of effective digits is 10, same as the display. If an operation result exceeds the
number of effective digits, the decimal fraction part is unconditionally truncated.
Tabulation (TAB) processing is performed on the operation result after the fraction part is
truncated. TAB processing includes rounding up and down, truncating, and raising the value
of the digit one below the specified decimal point. For floating points, all values are
truncated.
When the operation result is 0, the sign must be positive.
Intermediate values for addition, subtraction, multiplication, or division are displayed as a
floating representation regardless of the TAB specification.
