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.

If required, the PTT bezel and the PTT seal assembly can be disassembled using a small screwdriver 
as follows:

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. 

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.
