3-26 Theory of Operation: Controller
3.2.1.2.4 Data-Side Microphone
The data-side microphone is mounted on the front chassis and connects directly to the VOCON
board through a set of pogo pins mounted on the VOCON board.
3.2.1.2.5 Side Controls Flex
The side controls flex contains the PTT, Side Top button, Side Middle button and Side Bottom button.
The flex connects to the Expansion Board through a 10-pin connector.
3.2.1.2.6 Audio-Side Microphone, Speaker, and Bluetooth Antenna
The audio-side microphone and speaker flex assembly connects to the expansion board through
spring clips. The Bluetooth antenna is also part of this flex assembly and also connects to the
expansion board through spring clips.
3.2.1.2.7 RF Board
The RF board connects to the VOCON through a 40-pin board to board connector.
NOTE: See Table 7-2 on page 7-2 for pin assignments
