Fuse
In the rare event that the non-replaceable fuse blows on your RI-50 circuit board, the BLOWN FUSE
LED will light up while power is supplied to the RI-50. This indicates an internal fault and you will
need to replace your RI-50 unit.
¼ Note: A blown fuse indicates an internal fault with your RI-50. It does not indicate a fault with the
external wiring to the RI-50 or a fault with the radar pedestal.
