-25- Abstract of the Disclosure Programmable Service Reminder Apparatus and Method Electronic hourmeter devices having service reminders are useful, for example, in industrial vehicles. Advantageously, such service reminders should be field programmable for a variety of predetermined service intervals. The subject electronic service reminder is readily field programmable by authorized personnel and is protected from being programmed or reset by unauthorized personnel. A service status indicator apparatus is activated in response to the elapsed hourmeter time exceeding the programmed service interval time, and both the hourmeter elapsed time and the service reminder programmed time are resettable in response to a predetermined magnetic flux applied to respective Hall effect switches. Data is advantageously maintained in a non-volatile memory device without need for a battery back-up.
