REMIND
Use the remind button on the light path diagnostic panel to acknowledge that an
error has occurred without taking further action. When you push the remind button,
the system error LED will flash every 2 seconds until the error is fixed. If another
error occurs, the system error LED will then stop flashing and return to a solid on
state.

page 93.

indicate, and actions to solve the problems.
