Maintenance

If the FTI fails to indicate or respond, first check that the power supply is correct and turned on.

If the Remote Key-Switch input is connected, disconnect and try unit again.

If the unit still does not function it should be replaced by a new unit. FTI units are interchangeable and require
no setting up.
