2-12 MAINTENANCE
7.0 Radio Assembly
7.1 Chassis Assembly (for Low Power Models)
1. Ensure that the Fuji Poly Thermal Pad is on the small pedestal located on the PA
compartment of the chassis.
2. Verify that the potentiometer is soldered properly.
3. Take the main PCB and smear thermal paste on LDMOS Power Amplifier, TO220, and Audio
Power Amplifier.
4. Slide the main board diagonally into the chassis.
5. Tighten all eight screws (Torx T10).
6. Assemble the O-ring on the RF connector and tighten it using Torque 22 lb.in.
7. Tighten the RF connector security screw M2 using Torque 1.5 lb. (through the opening in the
PCB).
8. Take the Power Amplifier Clip and insert the leg-shape side into the opening groove located
on the PCB. Tighten the screw using Torque 13 lb.in
9. Take the PA Shield and place it on the PA compartment. Tighten the three screws using
Torque 13 lb.in. Tighten the middle screw first, then the screw located on the left side, and
lastly the screw located on the right side.
10. Insert the DC cable into the slot. Ensure that it is seated correctly on the chassis hook located
below the DC cable. Attach it to the chassis and PCB by tightening the two screws using
Torque 13 lb.in (Torx T10).
11. Take the main shield and place it on the chassis. Check that the corners of the main shield
are seated properly on the corner supports.
12. Take the main seal and place it inside the top cover. Verify that the main seal is seated prop-
erly on its placement ribs and all around the groove.
13. Take the upper cover, place it properly on the chassis, and push it down. Three click sounds
are heard from both sides and back.
7.2 Chassis Assembly (for High Power Models)
1. Verify that the potentiometer is soldered properly.
2. Take the main PCB and smear thermal paste on T0220 and Audio Power Amplifier.
3. Slide the main board diagonally into the chassis.
4. Tighten all eight screws (Torx T10).
5. Assemble the O-ring on the RF connector and tighten it using Torque 22 lb.in.
6. Tighten the RF connector security screw M2 using Torque 1.5 lb. (through the opening in the
PCB).
7. Take two PA Screws and place in screw holes over PA. Tighten the screws using Torque 13
lb.in.
8. Take the PA Shield and place it on the PA compartment. Tighten the three screws using
Torque 13 lb.in. Tighten the middle screw first, then the screw located on the left side, and
lastly the screw located on the right side.
9. Insert the DC cable into the slot. Ensure that it is seated correctly on the chassis hook located
below the DC cable. Attach it to the chassis and PCB by tightening the two screws using
Torque 13 lb.in. (Torx T10).
