    The recommended maintenance schedule for the 4380A is outlined in Table 6. Although this schedule is sufficient for most applications, it may be necessary to increase the number of scheduled maintenance events for extremely dusty or dirty environments. Contact Microsemi if there are questions about the scheduled maintenance cycle.
