step 10. Plug the 22-pin connector at the end of the keypad 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
bottom 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.
15. 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.
16. 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 casting downward toward the
bottom of the housing until they meet. Snap the housing
assembly and casting assembly together.
The main seal o-ring should not be visible when looking
at the back side of the radio. If the seal is visible, it is
improperly installed.
17. 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 main casting,
reinstall them.
Housing Assembly 1. Inspect the housing seal surfaces for debris. Remove any debris.
2. Install the controls seal (35).
3. Reassemble the controls bracket assembly (34) into the housing
(2) by snapping in the right side of the bracket first, then
snapping in the left side.

on page 47, install the frequency knob, new frequency
escutcheon, new frequency insert, secure lever, lightpipe, volume
knob, new volume insert, and o-ring.

the PTT area of the housing assembly (2). Make sure the spring
tabs on the backer fully engage the catch features on the housing.
