5. Carefully set the optional board into place, making sure to align the
mounting holes with the threaded standoffs on the main PCB. (The
Interface Board’s rear panel connector should align with the rectan-
gular cutout at the radio’s rear panel, and the rear edge of the option
board should be parallel to the main PC board.)
6. Look under the right edge of the Interface board to ensure that J912
is aligned with the mating connector on the option board. With the
board properly aligned, push down firmly in the area directly above
J913 and then over J912 at the edge. A distinct “locking” action will
be felt as the connectors engage.
7. Install the Phillips mounting screws with lockwashers on the top of
the FT1 board.
For protected versions only: Install the plastic clip, if supplied, at the
right rear corner of the Interface board. It slips over the edge of the
main PC board and the option board. Gently tighten the hex screw to
secure the clamp.)
The Interface board must be properly seated onto the LEDR radio’s
motherboard before powering up the radio chassis. Failure to properly
install the board could result in permanent damage to the motherboard
and the optional PCB.
8. Re-install the radio’s top cover. This completes the Interface Board
installation.
