Disassembly/Reassembly Procedures: Radio Reassembly
6. Plug the coaxial cable's connector (52) into the transceiver board's (48) surface-mount con-
nector, making sure to lead the coax's connector straight into the surface-mount connector.
An angled lead-in can damage the surface-mount connector or the center of the coax.
7. Reinstall the 26-pin compression connector (46). It can only be inserted in one way—with the
two-peg edge pointing downward on the left side.
8. If the radio is equipped with an encryption board (45), connect it to the back of the VOCON
board (44) through the 40-pin connector. Ensure that these connectors are properly engaged.
9. Reinstall the VOCON board (44). Tuck the tab at the top of the VOCON board into the reten-
tion slot on the casting, rotate the board into position, and engage the 26-pin connector.
10. Reinstall the VOCON board shield assembly (41), with keypad (models II and III only) and
four clips (40) attached, onto the casting. Snap the shield's clips down, alternating diagonally
across the shield.
11. If you are reassembling a model I radio, skip to step 14; if you are reassembling a model II or
III radio, complete the remainder of step 10. Plug the 22-pin connector at the end of the key-
pad flex's (43) tail into the connector on the VOCON board (44).
12. Reinstall the LCD module (38) and display locator pad (39). Position the LCD module, with
the display locator pad facing upward, so that the connector on the flex points toward the bot-
tom of the radio. Press the display locator pad (39) down over the two locator posts on the
casting, making sure that the locator pad's loops are fully captured by the casting posts.
13. Plug the 22-pin connector at the end of the display module (38) flex into the mating connector
on the VOCON board (44).
14. Reinstall the main seal (55) around the casting assembly (51). Start at the top of the casting
and work the seal around the perimeter of the casting until it is completely in place.
8.9.3 Join the Casting and Housing Assemblies
To join the casting and housing assemblies:
1. While holding the casting assembly (51) in one hand and the housing assembly (2) in the
other, plug the 40-pin connector on the controls flex assembly (18) into the connector on the
VOCON board (44).
NOTE: This can easily be done using the thumb of the hand holding the casting.
2. With the fronts of both the casting assembly (51) and housing assembly (2) facing downward,
carefully insert the top of the casting into the top of the housing assembly. Making sure that
the antenna bushing is inside the antenna hole in the control top, pivot the bottom of the cast-
ing downward toward the bottom of the housing until they meet. Snap the housing assembly
and casting assembly together.

3. Referring to the appropriate section in this manual, reinstall the universal connector cover or
any accessory connected to the radio, the antenna, and the battery.
NOTE: If the volume knob (6) or frequency knob (13) were removed prior to servicing the
