• Automatically moves away from interference without audio interruption
• RF back-channel for remote control of transmitter functions
• Globally­unlicensed 2.4 GHz and 5.8 GHz frequency band allows operation of up to 4 compatible systems in a typical set­ ting and up to 8 compatible systems under ideal conditions
• Automatic transmitter power-off to conserve battery life when transmitter is not in use

Quick Start

To reduce set up time, the transmitter and receiver automatically link to form an audio channel the first time they are powered on and never have to be linked again.
Note: When setting up multiple receiver systems, turn on and link each transmitter/receiver pair one at a time to prevent cross-linking.

Step ①| Connect power supply to the receiver and plug cord into an AC power source. Connect the audio output to an amplifier or mixer.
---|---
Step ②| Install charged transmitter batteries.
Step ③| Turn on the transmitter and receiver. The blue RF LED will flash while the transmitter and re­ ceiver form a link. When the link has successfully formed, the RF LED will remain illuminat­ed.
Note: The transmitter and receiver will remain linked for future usage. At power-up, the blue RF LED will illuminate, skipping the linking step.
Step ④| Check the audio and adjust the gain if necessary.

Installing Transmitter Batteries

Bodypack Transmitter

1. Move the locking lever to the open position and slide the battery door open.
2. Place the battery into the transmitter.
3. Close the battery door and slide the latch to lock.

Handheld Transmitter

1. Unscrew and remove the battery cover.
2. Place the battery into the transmitter.
3. Replace and tighten the battery cover.

Multiple Receiver Systems
For ease of set up, frequencies are divided into groups to best match the channel requirements for your system.
Select the group by determining the total number of receivers in your system (channel count). All receivers in the system must be set to the same group.

Group| Channel Count (Number of Re­ ceivers)| Number of Backup Frequencies| Notes
---|---|---|---
1| Up to 4| 3| Initial factory setting.
2| Up to 5| 3| Best multi-channel group if you experience interfer­ ence.
3| Up to 8| 0| For large multi-channel systems. Only use Group 3 in controlled Wi-Fi environments because there are no backup frequencies to avoid interference.
4| 1| 27| Best single-channel group if you experience interfer­ ence.

*Environmentally dependent, 4 systems typical
See “Tips to Improve Wireless System Performance” section for additional information.
Setting Up Receivers and Transmitters
Note: Before beginning, turn off all receivers and transmitters. Turn on and set up each receiver/transmitter pair individually to prevent cross- linking.

1. Turn on the first receiver.
2. Press and hold the group button to select a group (if necessary) or if the group is already set, press the channel button to scan for the best available channel.
3. Turn on the first transmitter. The blue rf LED will illuminate when a link is established.

Repeat steps 1-3 for each additional receiver and transmitter. Remember to set each receiver to the same group. Note: Dashes appearing on the group and channel display during a channel scan indicate that frequencies are not available in the selected group. Choose a group that supports more receivers and repeat the set up steps.
Manually Linking a Transmitter to a Receiver
Use the manual linking option to change the transmitter linked to a receiver. A common use for manual linking is changing the linked transmitter from a bodypack type to a handheld type.

1. Turn on the transmitter: Within 5 seconds, press and hold the LINK button until the transmitter LED begins to flash green.
2. Press and hold the link button on the receiver: The blue rf LED will flash, and then remain on when the link has been established.
3. Test the audio to verify the link and adjust the gain if necessary.

Combo Systems
A combo system is created by linking two transmitters to a single receiver. Only one transmitter can be active at a time to pre­ vent cross interference. Gain settings for each transmitter can be independently set and stored when the transmitter is active.
Important! Do not turn on and operate both linked transmitters at any time.
Turn off both transmitters before beginning.

1. Press the group button to select a group. The receiver automatically scans the selected group to find the best available hannel.
2. Turn on transmitter 1 and link it to the receiver. Adjust the gain, and then turn off the transmitter.
3. Turn on transmitter 2 and link it to the receiver. Adjust the gain, and then turn off the transmitter.

Firmware
Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are devel­ oped to incorporate additional features and enhancements. To take advantage of design improvements, new versions of the firmware can be downloaded and installed using the Shure Update Utility tool.
Software is available for download from http://www.shure.com/update-utility.

Operation

Gain Adjustment
Use the gain buttons on the receiver to increase or decrease the gain of a linked transmitter:

• Turn on the linked transmitter and momentarily press the gain buttons to adjust the gain in 1 dB increments
• For faster gain adjustments, press and hold the gain buttons

Tip: Monitor the audio and observe the receiver audio meter level while adjusting the gain to prevent signal overload.
Locking and Unlocking the Controls
The controls of the receiver and transmitter can be locked to prevent accidental or unauthorized changes to settings.
Note: Locks are not affected by power cycles.
Locking the Receiver Controls
Simultaneously press and hold the group and channel buttons until LK appears on the LCD. Repeat to unlock.

• LK is displayed if a locked control is pressed
• UN is displayed momentarily to confirm the unlock command

Locking the Transmitter Power Switch
Starting with the transmitter set to off, press and hold the LINK button while turning on the transmitter. Continue to hold the link button until the lock icon appears on the receiver LCD. Repeat sequence to unlock. Optionally, the transmitter power switch can be remotely locked from the receiver front panel:
Simultaneously press and hold the group and link buttons for approximately 2 seconds until the flashing lock icon appears on the receiver LCD. Repeat sequence to unlock.
Identifying Linked Transmitters and Receivers with Remote ID
Use the Remote ID feature to identify linked transmitter and receiver pairs in multiple receiver systems. When Remote ID is ac­tive, the receiver LCD will blink and display ID. The status LED of the corresponding transmitter will alternately flash red and green for approximately 45 seconds.
To activate Remote ID:

1. Momentarily press the link button on the transmitter or receiver.
2. The LCD of the linked receiver will blink and display ID and the status LED on the linked transmitter will flash red/green.
3. To exit Remote ID mode, momentarily press the link button or allow the function to timeout.

Manually Selecting a Group and Channel
Specific groups and channels can be assigned to the receiver instead of using the automatic scan function.
Note: Group 3 should only be used in controlled Wi-Fi environments to prevent interference from unexpected Wi-Fi devices.
Selecting a Group

1. Press and hold the group button for 2 seconds until the group display flashes.
2. Press the group button to scroll through the available groups.
3. The receiver will automatically save the selected group.

Selecting a Channel

1. Press and hold the channel button for 2 seconds until the channel display flashes.
2. Press the channel button to scroll through the available channels.
3. The receiver will automatically save the selected channel.

Note: A double dash symbol– displayed on the receiver screen during a channel scan indicates that there are no available channels within the selected group.
Choose a group with more channels and repeat set up steps.
