Position the TMP cables so they will be out of the way when you install the KRX3 module. Figure 48

shows a suggested arrangement. The exact cable positions are not important as long as they are below the top of

the SUBOUT board and so they will not interfere with installing the KRX3 module. Avoid kinking the cables.

Arrange them with smooth bends. You may need to unplug one end of the cable and twist the coax slightly so it

will lie in smooth curves where needed.

Figure 48. Positioning the TMP Cables.

Connect a 5” (13 cm) TMP cable to J5 on the KREF3 board (see Figure 49).

Connect a 5” (13 cm) TMP cable between J1 on the KREF3 board and J83 on the Aux KSYN3 board as

shown in Figure 49.

Check the position of both the SUBOUT and SUBIN interface boards to be sure they are still fully seated in

their corresponding connectors on the K3 RF board.

Check to ensure the battery cover is in place protecting the top of the battery from contact with the KRX3

enclosure (see Figure 44). The top edge of the battery is the positive terminal, and touching the enclosure during

installation will short-circuit the battery.
