Fix the antenna to the demo board.
Connect the DC power supply (or Battery) to the demo board. Please pay attention to the power polarity. The DC power voltage could be 3.3V-5V, but the recommend DC power is 4.0V; The current capacity should be double of the transmit current.
After connect the power supply correctly, the power Led would turn on.
When you press the PTT key，the red LED for transfer state indication will turn on. Now you may talk and then release the PTT Key. The red LED will turn off，it into the receive state，you may receive the talking from opposite side.
