Financial calculator with Large 10 digit LCD display. Hard protective case. Percentage and calendar functions. Interest calculations. Depreciation calculations.

Aurora FN1000 has been discontinued.

Note: The FN1000 has two separate test functions, an internal self-test, and a keyboard / display test. To perform the internal self-test, with the calculator off, press and hold the multiply key (or the plus key 1), press and release the ON / OFF key, then release the multiply key. The calculator will display: Fr H... for approximately nine seconds, Fr L... for approximately twenty seconds, CHE--Eb82H for approximately three seconds, and in cob until the self-test is exited. This self-test function cannot be exited by a key press until "in cob" is displayed. Exit this self-test by pressing ON / OFF, which will turn the calculator off, or by pressing any other key, which will cause the error indicator and "9" (error 9) to be displayed. (The self-test can be exited at any time by pressing the reset button on the back of the calculator). The FN1000 is curiously similar to the Hewlett-Packard HP-12C.
