Diagnostics
Note that diagnostic tests generally delete any data on the calculator. Be sure to back up any important information held in the calculator before running these tests.
While holding SHIFT and 7 keys (or just SHIFT key for early models) press the ON key. Pressing the SHIFT key cycles through the 14 display test patterns. Press SHIFT one more time to change the display from 0 to 1 for the start of the keypad test - the numbers then increase as each key is pressed in the correct order (omitting the ON key which exits test mode).
