systems you can install at a single venue. It scans for wireless interfer-
ence and finds the group with the most open channels.

Multiple Systems

To maximize performance, set all wireless systems to different channels
from the same group. These channels are selected to work well together.
Follow these steps when using group and channel scan with multiple
systems.
1. Power off all system transmitters. Turn on all other wireless or digital
devices as they would be during the performance or presentation.
2. On the first receiver: Perform a group scan. Note the selected group,
then use channel scan to find the first open channel in that group.
3. Power on the first transmitter and set it to the selected group and
channel.
4. IMPORTANT: Leave the first transmitter powered on while setting up
the next system.
5. For each additional system: Set to the same group as the first.
Perform a channel scan and set the receiver and transmitter to the
selected channel.
6. Leave each transmitter on while setting up additional systems.
Note:
• Keep each transmitter at least two meters (6 feet) apart.
• If using systems from different bands, set up all systems from the same
band together.
Tip: To reduce setup time, you can manually set up the group and chan-
nels before arriving at the venue. Visit www.shure.com for a list of groups
and channels that are anticipated to be free of interference in a particular
city or region.
