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, two-way radios, computers, media players, Wi-Fi
devices, and digital signal processors
Charge or replace the transmitter battery
Keep transmitters more than two meters (6 feet) apart
Keep the transmitter and receiver more than 5 meters (16 feet) apart
During sound check, mark trouble spots and ask presenters or performers to avoid those areas
