3-8 Maintenance
3.6.4 Speaker, Microphone, and Universal Connector Flex Disassembly
1. If disassembly of the speaker-microphone assembly is necessary, remove the dustcover by
turning the screw at the bottom of the dustcover counterclockwise with your fingers. Lift the
dustcover out of its pocket.
2. Using a screwdriver, push down on the portion of the speaker retainer bracket pointing toward the
bottom of the radio. Then, remove the retainer by slightly pushing it toward the top of the radio
until you slide it past the front cover slot.
3. Pull the rubber microphone boot from its seated position. Unless you are replacing the
microphone, leave it in the boot.
4. Peel-off the universal connector flex circuit escutcheon (label).
5. Pry the flex circuit (adhesive held) backer board away from the front cover, and remove the
universal connector tail of the speaker-microphone assembly through its opening in the front
cover.
6. After the universal connector tail of the speaker-microphone assembly is removed, the assembly
can be completely removed. If it is necessary to replace the speaker or microphone, or both, do it
while the flex circuit is removed from the front cover. When reassembling the microphone in its
boot, make sure the microphone port faces the round hole in the bottom of the boot.
Figure 3-8. Removal Speaker-Microphone Assembly
NOTE
At this point, the Option Board Installation Procedure should be performed, if necessary.
(See page 3-12)
NOTE
The dustcover must be removed to remove the speaker-microphone assembly flex circuit.
The speaker is held in place with a two-legged retainer bracket. The bracket legs are secured
by the front cover slots. Be careful not to damage the speaker when removing the retainer
bracket.
NOTE
The speaker-microphone assembly flex circuit goes through the front cover wall to
the outside wall. To replace this assembly, you must peel-off the universal connector
escutcheon label. The existing escutcheon cannot be reassembled; a new part must
be used. (See item number 10 on the exploded view drawing on page 3-13).
