1.Put the housing assembly (1) aside.

2.Remove the main seal/toggle support (63) from around the chassis assembly (13).

NOTE: Inspect the main-seal/toggle support for damage. If it is damaged, replace with a new seal prior to reassembly.

3.With the front of the radio facing upward, remove the three chassis bolts (60) from 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).

4.Remove the front chassis assembly (50).

5.Disconnect the encryption board (67), if present, by separating the 40-pin connector from the VOCON board (64).

6.Disconnect the 20-pin control flex connector and the 20-pin display flex connector from the VOCON board (64).

7.Remove the VOCON board (64) from the back chassis (13) by lifting the board from the bottom and pulling the board out and away from the assembly.

8.Lift out the 26-pin compression connector (62).

9.Remove the main shield (61) and transceiver board (65) from the back chassis (13) in unison by lifting both parts from the bottom of the radio until they clear the center boss of the back chassis. Once clear of the center boss, they can be pulled out and away from the assembly.

NOTE: Inspect the back chassis (13) to make sure that the thermal pad (26) is attached to the chassis. If the pad is attached to the transceiver board, remove it from the board, discard it, and attach a new thermal pad to the chassis heat sink island.

10. Separate the main shield (61) from the transceiver board (65).

NOTE: Inspect the conductive gasket of the main shield for damage. If the conductive gasket seal is damaged, discard the main shield and replace it with a new one.

NOTE: The hex lock nuts (16), which hold the housing to the chassis assembly (13), are located in recesses at the bottom of the back chassis. These nuts are retained by the hex lock nut retainers (17). If the hex lock nuts need to be replaced, they can be removed with tweezers.
