3. Wireless Voice Transceiver Reference Design Demonstration
The following steps are necessary to assemble and demonstrate the operation of this reference design:
1. Screw-in the provided antennas to the wireless voice transceiver boards. Do not over-tighten.
2. Plug in the headset microphone connector (pink color) to the

connector (green color) to the board socket labeled
“Headphone.” Make sure that both connectors are plugged in
all the way into the sockets. The sockets might be tighter than
normal on the first use. Repeat the same for the second board.

each power supply to wall power with the other end connected to the boards’ power socket. Power is indicated
by the LED labeled “POW.”
to transmit a low frequency tone that can be heard on the other end. The LED labeled P15 will light up
whenever the local audio level is above the configured audible threshold. The LED labeled P16 will light up
during transmission.
