7-16 Disassembly/Reassembly Procedures: Reassembly Procedures for SSE 5000 Radio

7.7.2Reassemble the Chassis Assembly

1.Ensure that the thermal pad (26) is attached to the back chassis (13). If it is not, attach a new thermal pad to the chassis heat sink island.

2.Install the transceiver board (65) by orienting the board at an angle so that it can be inserted into the antenna contact area of the back chassis (13), with the alignment post of the back chassis aligned with the alignment hole of the board. Once the chassis post and the board hole are aligned, the board can be lowered onto the support rails of the back chassis.

NOTE: Take care not to snag the RF contact clip (69) or the RF ground clip (35) on the back chassis during assembly.

3.Install the main shield (61) by orienting the shield at an angle so that it can be inserted into the antenna contact area of the back chassis (13), with the alignment post of the back chassis aligned with the alignment hole of the main shield. Once the chassis post and the main shield hole are aligned, the main shield can be lowered onto the surface of the transceiver board.

4.Install the 26-pin compression connector (62). It can only be inserted in one way: with the two-peg edge pointing downward on the right side.

5.While holding the 20-pin connectors of the control and display flex away from the surface of the main shield (61), install the VOCON board (64) by orienting the board at slight angle so that it can be inserted into the antenna contact area of the back chassis (13), with the alignment post of the back chassis aligned with the alignment hole of the board. Once the chassis post and the board hole are aligned, the board can be lowered onto the main shield.

6.Plug the 20-pin connector at the end of the LCD module flex into the mating connector on the VOCON board (64).

7.Plug the 20-pin connector at the end of the controls flex into the mating connector on the VOCON board (64).

8.If so equipped, install the encryption board (67) by orienting the board at a slight angle so that it can be inserted under the LCD bracket (21), while the board is being plugged into the 40- pin connector of the VOCON board (64).

9.Place the hex lock nut retainers (17) into the rounded end of the hex lock nuts (16).

10.Place two lock nuts (16) with retainers (17) into the lock nut recesses at the bottom of the back chassis (13), orienting the hex lock nut retainers towards the top of the radio and the flats of the nuts parallel to the sides of the nut recesses.

11.Install the front chassis assembly (50) into the back chassis assembly (13), orienting the speaker cone (56) towards the outside of the radio, and using the three chassis bolt bosses as assembly guides.

12.Insert three chassis bolts (60) through the front chassis (50). Using a ROTO-TORQ adjustable torque screwdriver with a T-10 TORX bit (see Table 7-2 on page 7-10for part numbers), tighten the three chassis bolts to 18 in-lbs.

13.Install the main seal/toggle support (63), orienting the toggle support part of the seal such that it hangs towards the bottom of the radio at the toggle switch side of the radio. Ensure that the main seal is captured between the front and back chassis and the control top (40).

14.Push the toggle switch support into the area between the front and back chassis, directly under the toggle switch backer.

7.7.3Join the Chassis and Housing Assemblies

1.While holding the chassis assembly (13) in one hand and the housing assembly (1) in the other, insert the chassis assembly into the housing, orienting the speaker towards the front of the radio.
