Tips to Improve Wireless System Performance

If you encounter interference or dropouts, try the following suggestions:
• Choose a different receiver channel
• Reposition the receiver so there is nothing obstructing a line of sight to the transmitter (including the audience)
• Avoid placing transmitter and receiver where metal or other dense materials may be present
• Move the receiver to the top of the equipment rack
• Remove nearby sources of wireless interference, such as cell phones, two­way radios, computers, media play­
ers, Wi-Fi devices, and digital signal processors
