The second time the display appears the O's are changed to 1 's,
the third time to 2's and so on until all 9 ' s appear. Once the
cycle, O's through 9 's, has been completed the program auto-
matically recycles and will continue to do so until the 'STOP'
key has been pressed.
One cycle of 0' through 9 's is sufficient to verify that the calcu-
lator is operating satisfactorily.
The calculator is not operating correctly:
if there is no display at all after about
10
seconds,
if the display appears but remains fixed,
if there is a display, fixed or flashing, different from the
display shown above.
lf one of these should occur, first make sure that the four
swit ches (in particular the ' DEGREES / RADIANS' switch), lo-
cated above the keyboard, are correctly set; then carefully re-
peat the entire procedure to ensure that no error was made the
first time.
lf the cafculator still will not operate then refer to the warranty,
on the inside front cover of th1s manual, for assistance from
your nearest Sales and Service Office.
