Maintenance
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.
A minimal amount of maintenance is required for the 4380A. It is designed to operate continuously over
long periods of time with little to no interaction. The primary factor in maintaining a working unit is to
verify that it remains dust free and the antenna and antenna cable are in good condition. The following
maintenance schedule is applicable.
Removing power is not required to perform maintenance on this unit.

5.1 Fan Filter
The fan filters help protect the system from accumulating dust inside the unit as well and allows the fans to
provide the proper level of cooling for the internal components. It is important to keep this filter clean to
allow the proper level of air flow to prevent the system from overheating. To clean the filter:
1.
Remove the fan assembly from the front by loosening the two captive screws.
2.
Remove the filter from the fan assembly.
3.
Use a vacuum cleaner to clean the fan filter of any accumulated dust.
4.
Re-install the filter and assembly into the chassis. Take care to feed the cable into the chassis
while inserting the fan assembly.
5.2 Antenna and Antenna Cable Inspection
The Antenna and antenna cables are a common source of failure because they are exposed to harsh
environmental elements. The following process outlines the steps required in performing an inspection of
the antenna and antenna cable.
1.
Follow the antenna cable from the rear of the 4380A to the antenna. Look for any severe bends in
the cable or damage to the shielding of the cable.
2.
Remove any severe bends in the cable and replace any cables that have damaged shielding.
3.
Examine the portions of the cables that are exposed to the elements. Look for signs of excessive
weathering such as a deterioration of the outermost insulator. Replace any cables that appear
severely weathered.
4.
Inspect the antenna. Clean any buildup of dirt or other contaminants from the surface of the
antenna. These contaminants may degrade the strength of the GPS signal. If the antenna has been
damaged by the weather, replace it.
5.
Verify that the antenna is still securely mounted.

In extreme operating environments it may be necessary to clean the fan filter more frequently.
