Manually Setting Receiver Group And Channel; Tips To Improve Wireless System Performance - Shure BLX4R Quick Start Manual

Before you begin system set up, turn all receivers ON and all transmitters OFF.
For the first receiver:
1. Perform a group scan to find the group with the most clear channels.
2. Turn on the first transmitter and change the group and channel to match the receiver.
3. Leave the transmitter on and continue with the additional systems.
Note: If the selected group does not contain enough open channels, manually select group "d" when setting up
larger systems.
For each additional receiver:
1. Manually change the receiver to match the group setting of the first receiver. Recall that each time the group
setting is changed, a channel scan is automatically done.
2. Turn on the transmitter and change the group and channel to match the receiver.
3. Leave the transmitter on and continue to the next system.
4. Once all receivers are set up, perform an audio check on all microphones.

Manually Setting Receiver Group and Channel

The receiver group may need to be changed as part of a multiple system setup.
Group (letter)
1. Hold the group button on the receiver until the display begins to flash.
2. While the display is flashing, press the group button again to advance to the next group.
Note: Only the group setting will be displayed during the manual setup.
3. Once the desired group is reached, release the group button. The receiver automatically performs a channel
scan.
Channel (number)
Always use a channel selected by the channel scan. However, if necessary, the channel can be set manually. Fol­
low the same steps above using the channel button instead of the group button.

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
• Charge or replace the transmitter battery
• Keep transmitters more than two meters (6 feet) apart
