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.

1. Pry back the T-tab found inside the front cover (in between the four buttons on the PTT
assembly).
2. Remove the PTT bezel by slightly bowing it until the top and bottom tabs are released from the
slots in the front cover.
3. The PTT seal can be easily lifted from the bezel without the use of tools.

3.6.6 Control Top Disassembly

1. To remove the control top assembly, place a screwdriver next to the antenna boss, then pry it
against the control top escutcheon. This lifts the control top escutcheon away from its
double-sided adhesive. Grab the double-sided adhesive near the volume potentiometer, then lift it
away.
2. Remove the integrated control top seal, emergency button, and transmit light pipe.
