1 mW ≤100 ft.
10 mW ≤300 ft.
20 mW ≤420 ft.
Note: Using the 20 mW setting decreases the transmitter battery runtime
and reduces the number of compatible systems. See the specifications
section for details.

Scan and Sync

Use this procedure to tune a receiver and transmitter to the best open channel.
Important! Before you begin:
Turn off all transmitters for the systems you are setting up. (This prevents
them from interfering with the frequency scan.)
Turn on potential sources of interference such as other wireless systems or
devices, computers, CD players, large LED panels, effects processors, and
digital rack equipment so they are operating as they would be during the pre-
sentation or performance (so the scan will detect and avoid any interference
they generate).
1. Perform a channel scan on the receiver:
2. Select a group and press the
while it searches for an open frequency.
3. After the scan completes, the receiver displays the group, channel and
frequency of the best available channel. Press the flashing
save the value to the receiver.
4. Power on the ULXD transmitter.
5. Press the button on the receiver.

now tuned to the same frequency.

Multiple System Setup

A setup using networked receivers is the fastest and easiest way to distribute
the best open channel to each system. See Networking Receivers for network-
ing details.

Networked Receivers

1. Turn on all receivers.
2. Conduct a group scan on the first receiver to find the best group of frequen-
cies in your RF environment:

best channel to each receiver on the network.
4. Turn on a transmitter and sync to the receiver. Repeat this step for each
additional system.

Interference Detection

Interference Detection analyzes the quality of the RF signal and detects
interference conditions that have caused an audio signal dropout. When in-
terference is identified, the RF LEDS illuminate red and the following warning
displays on the receiver LCD panel.
Perform a Scan and Sync during a performance break if the warning display
persists or the audio drops out repeatedly.

Non-networked Receivers

1. Turn on all receivers.
2. Conduct a group scan on the first receiver to find the best group of frequen-
cies in your RF environment:
3. Select a group that contains enough open frequencies to accommodate the
entire setup.
4. Turn on the transmitter and sync to the first receiver.
