36 — TimeCard Tabulator II
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
must hit the
o 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.
Manual Reset
If your calculator should ever freeze or
“lock up,” press Reset - a small hole
located on the back of the calculator.
It is recommended that you use a
straightened paperclip.
