   • Press the SYNC button on the receiver for the selected channel. The IR indicator on the receiver will flash.
   • Align the IR sensor on the handheld microphone (usually near the bottom of the display) with the IR window on the receiver. Hold them close (within 10-20 cm) until the microphone's display shows the same frequency as the receiver and the SYNC indicator on the receiver stops flashing.
   • Repeat this process for the second microphone on the other channel.
7. Úvodní zvuková zkouška: Speak into each microphone while observing the audio level indicators on your mixer or PA system. Adjust the volume controls on the receiver and your audio system as needed.
