Reassembly

If your K3 is equipped with the KRX3 Subreceiver, turn to your KRX3 Subreceiver Installation and

Operation manual, Installing the KRX3 Subreceiver Module section to replace the KRX3 module. Be especially

careful to do the following as described in that procedure:

Be sure the cover on battery BT1 on the K3 RF board is in place. The cover is essential to avoid

shorting the battery. The outer rim of the battery is the positive terminal, and may come in contact with

the grounded bottom of the KRX3 enclosure if the cover is not in place.

Be sure all the TMP cables are properly connected or your K3 will not operate properly.

Be sure the TMP cable to J85 on the subreceiver module is routed as shown to prevent signal leakage

between the KRX3 and the K3 main receiver.

REPLACE ALL THE SCREWS!

The K3's chassis has excellent rigidity despite its light weight. The screws that hold the top

cover in place are an important part of the structural design. Be sure to replace all the

screws and verify they are tight whenever you replace the cover or other panels

If you removed it, replace the chassis stiffener bar as shown in Figure 13. Some stiffener bars do not have

permanently-attached PEM nuts for the screws attaching them to the KPA3 shield. If not, you found 4-40 nuts

when the bar was removed. Place the lock washers under the nuts instead of under the screw heads.
