Toggle/Reset Switch; Hour Meter Replacement - Freestyle MN126-1 Service Manual

5.11.4 Toggle/Reset Switch

This switch toggles the display or resets the maintenance channel depending
on the activation time and the current display mode.
Upon power-up, the display defaults to the historical display mode. The
display will remain in historical mode until the pushbutton is used to toggle
the display into maintenance mode. The hour meter will remain in this
mode until toggled or until power is removed. The "h" icon will remain
on and a "wrench" icon will be displayed below the "h" icon. As with the
historical display mode, the "h" icon will flash to indicate that time is
being accumulated and the "wrench" icon will remain on solid. The
historical channel cannot be reset. To reset the maintenance channel,
begin with the module in maintenance mode, and then press the
toggle/reset switch for five seconds. A reset is indicated by a "0" display.
