Radio Disassembly — Detailed
NOTE The speaker is held in place with a two-legged retainer bracket. The bracket legs are
secured by slots in the front cover. Be careful not to damage the speaker when
removing the retainer bracket.
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. Using care not to pull on the flex cable, pull the rubber microphone boot from its seated position.
Unless you are replacing the microphone, leave it in the boot.
NOTE The PRO9150 radio has a different microphone and microphone boot then is used in
the other PRO series models. These are NOT interchangeable.
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 paragraph 3.8).
4. Peel-off the universal connector flex circuit escutcheon (label).
5. Carefully 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. 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.
