Option 4 may be available if there is a keypad error. The CLEAR SERIAL # OR TAMPER ERROR function may be accessed if you have encountered either a SPED Serial # error 617 (usually when keypad has been replaced) or if a tamper condition has occurred.

Press option 4 (if available) to attempt clearing either of these error conditions.

NOTEIn the event the terminal displays error codes in the 592-617 range (keypad specific), option 4 in the Keypad functions may be an available option. If it is, attempt to clear the error by selecting this option.
