Explanation of lock keys
[0, 1, 2, 3]..............
[4, 6, A, AII]
Sets the specified decimal point. If no specification, floating is set.
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. When
AII mode is specified, key-entered data are multiplied by 1/100 only when the
key-entered numerical value is used for multiplication/division by [=] key. If the []
key is pressed during data entry, AII 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
P/
] ................. Switches between print and non print mode. When [ NP
P/
] lock key is off, disables
all printing except [PF] or [#/P] key.
When mode changes from non-print to print, feeds the paper one line.
[IC+]......................
[IC±]
Selects item count mode.
IC+.........Counts up by the [+] or [-] key.
IC±.........Counts up by the [+] key, down by the [-] key.
[S] ......................... If an operation is performed by the [=] or [%] key in auto accumulation calculation
mode, adds the operation result to the addition/subtraction register and
increments the item counter.
[GT] ...................... In grand total mode, adds the total register to the GT register by the [*] key.
SETI .................
SETII
When the [SETI/SETII] lock key is on, prints and express the stored tax rate. When
the [SETI/SETII] lock key is off, store the expression data to the new tax rate. The
result of tax rate is only floating-point, and not concent the decimal-point at this
function.
[FEED] ................. Feed paper.
[TMR] ................... When the [TMR] lock key is on, auto power-off functions.
(after approx. 6 minutes.)
[ /12
10
].................. Selects 10 digits display and printer when the [ /12
10
] lock key is off; Selects 12
digits display and printer when the [ /12
10
] lock key is on.
ECT
400E
................ Switches between the M400E printer and other printers (M400A, M401A, or M80)
to be used.
When the [400E/ECT] lock key is on, selects the M400E printer.
When the [400E/ECT] lock key is off, selects other printers (M400A, M401A, or
M80).
[2 TAX] ................. Switches between single tax and double tax mode.
When the [2 TAX] lock key is on, one tax rate can be set. (SETII and TAXII will be
disabled.)
When the [2 TAX] lock key is off, two tax rates can be set.
[2 M] ..................... Selects single memory or double memory mode.
When the [2 M] lock key is on, one memory can be used. (MII will be disabled.)
When the [2 M] lock key is off, two memories can be used.
