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

board socket labeled “Mic”. Plug in the headset headphone

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.

3. Choose appropriate plugs for the universal power supplies

depending on your location and snap them in place. Connect

each power supply to wall power with the other end connected to the boards’ power socket. Power is indicated

by the LED labeled “POW.”

4. After the above steps, you should be able to talk via one board and listen with the other. Press the SW1 switch

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.
