6.4 Speaker, Microphone, and Universal Connector Flex Disassembly

1. Turn the screw at the bottom of the dustcover counterclockwise with your fingers. Lift the dust-

cover 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 micro-

phone, 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.

Figure 3-7 Removing the Keypad Retainer and Other Boards from the Radio Body

NOTE

At this point, the Option Board Installation Procedure should be performed, if necessary.

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 out-

side 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.)
