3. Unplug the Molex connectors from the RF PCB

(see Figure 5-6).

4. If the top RF cable is not already marked, label it

so that the RF cables can later be plugged into the

proper positions on the new PCB.

5. Using a

⁄16" wrench, carefully remove the two RF

cables from the RF PCB. Hold the RF connector

ferrules while loosening the connectors to avoid

excess stress on or twisting of the cables (see

Figure 5-7).

6. Using a

⁄4" nut driver/socket, remove the four 1

⁄16"

standoffs and set aside.

7. Remove the old RF PCB.

8. Install the new RF PCB, making certain to align

the PCB so that the RF connectors are facing

inward (see Figure 5-1 on page 105).

9. Apply a drop of Loctite to one end of the four 1

⁄16"

standoffs. Install the four standoffs, Loctite-

applied ends facing the RF PCB. Secure in place

using the nut driver.

10. Reattach the RF cables, making certain to connect

them in their original positions (marked cable on

top).

11. Reattach the Molex connectors to the RF PCB.

12. Insert the split rubber grommet surrounding the

Molex connector cables into the small slot on the

new RF PCB cover.

13. Secure the RF PCB cover using the nuts and

washers removed in Step 2.

Failure to hold the ferrules tightly

while loosening the RF connectors

can result in damage to the cables

and reduce the signal quality.
