Power on the transmitter.
Press the SYNC button on the receiver.
Align the IR windows between the transmitter and the receiver so that the IR LED illuminates red. When complete,
Sync Success! appears. The transmitter and receiver are now tuned to the same frequency.
Note:
Any change to the encryption status on the receiver (enabling/disabling encryption) requires a sync to send the settings to the
transmitter. New encryption keys for the transmitter and receiver channel are generated on every IR sync, so to request a new
key for a transmitter, perform an IR sync with the desired receiver channel.
Setting the Frequency Manually
The transmitter can be manually tuned to a specific group, channel, or frequency.
Navigate to the Radio menu and select Freq.
Scroll to select G: and C: to edit the group and channel, or select the frequency parameter (MHz). When editing the fre
quency, press enter once to edit the first 3 digits, or twice to edit the last 3 digits.
Use the ∧∨ buttons to adjust the group, channel, or frequency.
Press enter to save, and then press exit when finished.
Updating 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, you can upload and in
stall new versions of the firmware by using the Shure Update Utility. The Shure Update Utility is available for download from
http://www.shure.com/.

Firmware Versioning
When performing an update, first download firmware to the receiver, and then update transmitters to the same firmware version
to ensure consistent operation.
The firmware numbering for Shure devices uses the following format: MAJOR.MINOR.PATCH (e.g., 1.2.14). At a minimum, all
devices on the network (including transmitters), must have the same MAJOR and MINOR firmware version numbers (e.g.,
1.2.x).
Updating the Transmitter
Download the firmware to the receiver.
Access the following menu from the receiver: Device
Configuration > Tx
Firmware
Update.
Align the IR ports between the transmitter and the receiver. IR ports must be aligned for the entire download, which can
take 50 seconds or longer.
Tip: The red alignment LED will turn on when the alignment is correct.
Press ENTER on the receiver to begin the download to the transmitter. The receiver will display the progress of the up
date as a percentage.
RF Mute
RF Mute prevents transmission of the audio by suppressing the RF signal while allowing the transmitter to remain on. The
home screen displays RF MUTED in this mode.
From the Radio menu, navigate to Output.
Choose one of the following options:
On: RF signal is active
Mute: RF signal is disabled
Press enter to save.
Turning the transmitter off and on or replacing the battery will restore Output to On.
Safe Start
Power on in Safe Start mode to prevent interference with other devices. Hold the exit button while powering on your device un
til the Safe Start menu appears.

Tip: To exit the Safe Start menu, cycle the power or momentarily remove the battery.
Note: Previous settings for locks and RF will be retained when the transmitter is powered on in Safe Start.
Input Overload
The OVERLOAD message is displayed when the audio input experiences a high-level input signal. Reduce the input signal or
move mic away from the source to remove the overload.
Tone Generator
The transmitter contains an internal tone generator that produces a continuous audio signal. The tone is helpful when conduct
ing a sound check or for troubleshooting the audio signal chain. The level of the tone is adjustable from -60 dB to 0 dB and the
frequency can be set to 400 Hz or 1000 Hz.
Tip: Always start with the level set to -60 dB to avoid overloading speakers or headphones.
From the Audio menu select Tone Gen.
Set the frequency to 400 Hz or 1000 Hz.
Select Level and use the arrow buttons adjust the value between -60 dB and 0 dB.
Turn off the tone by selecting Off from the menu or by cycling the transmitter power.

Matching Audio Levels with Offset
When linking two or more transmitters to a receiver, there may be a difference in volume levels between microphones or instru
ments. If this occurs, use the Offset function to match the audio levels and eliminate audible volume differences between trans
mitters. If using a single transmitter, set Offset to 0 dB.
Turn on the first transmitter and perform a sound check to test the audio level. Turn off the transmitter when finished.
Turn on the second transmitter and perform a sound check to test the audio level. Repeat for any additional transmit
ters.
If there is an audible difference in the sound level between the transmitters, navigate to the Offset menu (Audio >
Offset) in the transmitter to increase or decrease the Offset in realtime to match the audio levels.
