SERVICE REMINDER Two years have passed or the heating muffle has been in use for more than 1200 firing hours since the last inspection of the furnace. Ivoclar Vivadent therefore recommends that your furnace should be inspected. Please refer to the Equipment Service Passport or the Operating Instructions for further information. The interval until the next appearance of the note can be set in the Settings.
"If it ain't broke don't fix it". So basically if everything is fine and your calibrations are good and your pressings are good then stay the course. Like Terry says, Service Reminder.
