APPENDIX
Display Accuracy
TimeCard Tabulator has a 10-digit internal
accuracy with a 5/4 rounding technique
for an accurate 8-digit display.
Errors
When you make an incorrect entry, or
the answer is beyond the range of the
calculator, it will display the word
"Error." To clear an error condition you
o
must hit the
button. At this point you
must determine what caused the error
and rekey the problem. An error will
also occur if you enter a mathematical
impossibility such as division by zero.
Automatic Shut-off
If left on more than eight minutes without
activity, the Auto Shut-off feature shuts
the calculator off. When this occurs, all
values shown on the display are
cleared. An activated Timer/Stopwatch
disables the Automatic Shut-off.
Full Reset/Clear All
Your calculator is programmed with a
special two-key sequence, C x.
This key sequence clears all Memory
registers and resets the calculator to its
default state.
