The screws should be tightened diagonally. Fasten the upper right screw of the top Diplexer
and then the lower left screw of the bottom Diplexer, then fasten the upper left screw of
the top Diplexer and then the lower right screw of the bottom Diplexer. Once the outer
screws have all been partially tightened, repeat this process in a similar fashion with the
central screws. Then proceed to fully tighten all the screws in the same order.

Attach the Radio unit to the Diplexer unit using the 8 M5 captive screws supplied with the Radio kit. Position
the Radio unit on the Diplexer unit so that the two location pins mounted on the TRX ports of the Diplexer
unit fit into the corresponding holes in the Radio unit. Perform the fastening in diagonal fashion as in the
previous steps. The location pins are located on either the left of the upper TRX port and the right of the
lower TRX port or the right of the upper TRX port and the left of the lower TRX port, depending on the
frequency.
