Speaker,

Flex Disassembly
For this section, please refer to the Model III exploded view and parts list on page 35 for
part numbers and more information on the location of parts in the radio.
1. The speaker-microphone assembly can be removed without the disassembly of the
display or the keypad assemblies. If disassembly of the speaker-microphone assembly
is necessary, removal of the universal connector dust cover is optional (see Figure 23
on page 40).
2. Remove the plastic spacer at the bottom of the speaker. The spacer can be removed by
pulling upward with a slight, side-to-side motion until it clears the retaining ribs in the
front cover. Take special care to prevent damage to the tail of the speaker flex circuit
while the flex is still in place.
3. Using a screwdriver, push down on the portion of the speaker retainer bracket that is
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.
4. Remove the microphone boot retainer by inserting a penknife-sized screwdriver in the
notch between the retainer and the housing. Pry the retainer away from the housing
and remove the clip.
5. Remove the microphone rubber boot by sliding it out of the pocket in the front cover.
Take care not to pull on the flex cable while pulling on the microphone boot. Unless
you are replacing the microphone, leave it in the boot. At this point, the speaker and
microphone are disconnected, but the assembly is still attached to the universal
connector by 13 pins in the printed circuit backer board.
6. To remove the speaker-microphone flex circuit from the universal connector,
carefully grasp the flex circuit at a point directly across from the universal connector
pins. Applying firm pressure, gradually pull the flex away from the pins.
