Fuse Replacement
The Flex-1500 contains a 3 Ampere, standard automotive type AutoFuse Mini fuse to

The fuse, component designator F1, is located on the RF Power Amplifier board

removed by pulling the fuse away from the board. It is replaced by inserting the contact
blades into the fuse holder, and pushing downwards towards the PC board.
