About
Displays the following transmitter information:
Reset All
Restores all transmitter parameters to factory settings.
Use IR Sync to form an audio channel between the transmitter and receiver.
Note: The receiver band must match the band of the transmitter.
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.
The transmitter can be manually tuned to a specific group, channel, or frequency.
RF mute prevents transmission of the audio by suppressing the RF signal. The home screen displays RF MUTED in this mode.
When a transmitter is in RF mute mode, the RF will remain muted when the power is cycled and when the battery is replaced. To restore the RF signal, return to the Output menu and select On.
Power on in Safe Start mode to prevent interference with other devices. Hold the X button while powering on your device until the Safe Start menu appears.
Safe Start menu options:
Use the navigation buttons to make changes.
To exit the Safe Start menu, cycle the power or momentarily remove the battery.
Previous settings for locks and RF will be retained when the transmitter is powered on in Safe Start.
The OVERLOAD message appears when the audio input experiences a high-level signal. The power LED turns red as an additional indicator of an overload. Reduce the input signal or enable the input pad to remove the overload condition.
Tip: To enable the input pad, navigate to and select -12 dB.
The transmitter contains an internal tone generator that produces a continuous audio signal. The tone is helpful when conducting 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.
Always start with the level set to -60 dB to avoid overloading speakers or headphones.
Turn off the tone by selecting Off from the menu or by cycling the transmitter power.
When linking two or more transmitters to a receiver, there may be a difference in volume levels between microphones or instruments. If this occurs, use the Offset function to match the audio levels and eliminate audible volume differences between transmitters. If using a single transmitter, set Offset to 0 dB.
The ShowLink Test is a tool to find the boundaries of the ShowLink coverage area. When the ShowLink test is activated, a five-bar display indicating the link quality is shown on the screen. As the transmitter moves away from the access point, the number of bars will decrease. ShowLink control is maintained as long as 1 bar is displayed.
If the transmitter is beyond the coverage range, ShowLink control will not be possible. However, the audio signal will not be affected or interrupted as long as the transmitter is within range of the RF signal.
To improve coverage, adjust the location of your access points or place additional access points to extend coverage.
To activate the ShowLink Test:
Tip: During a ShowLink test, press O (enter) to drop a marker in Wireless Workbench.
Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are developed to incorporate additional features and enhancements. To take advantage of design improvements, you can upload and install new versions of the firmware by using the Shure Update Utility, available on the Shure Update Utility page.
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).
Tip: The red alignment LED will turn on when the alignment is correct.

Make sure that the receiver and transmitter are receiving sufficient voltage. Check the battery indicators and replace the transmitter batteries if necessary.
Adjust the system gain on the front of the receiver. Ensure the output level on the back of the receiver corresponds to the mic/line input setting of the mixing console, amplifier, or DSP.
Check that all cables and connectors are working correctly.
The transmitter and the receiver can be locked to prevent accidental or unauthorized changes. A locked feature or button will produce the Locked screen on the LCD panel or the lock icon will flash on a transmitter.
Re-sync all receivers and transmitters after enabling or disabling encryption.
Paired transmitters and receivers must have the same firmware version installed to ensure consistent operation. See Firmware topic for firmware update procedure.
If the transmitter battery does not cool off, the transmitter will shut down. Let the device cool down and then consider swapping the transmitter battery to continue operation.
Identify any possible external heat sources to the transmitter and operate the transmitter away from those external heat sources.
All batteries should be stored and operated away from external heat sources in reasonable temperature conditions for best performance.
If neither blue RF Diversity LED is illuminated, then the receiver is not detecting the presence of a transmitter.
The orange RF Signal Strength LEDs indicate the amount of RF power being received. This signal could be from the transmitter, or it could be from an interfering source, such as a television broadcast. If more than two of the orange RF LEDs are still illuminated while the transmitter is off, then that channel may be experiencing interference, and you should try a different channel.
The red RF LED indicates RF overload. Overloads have the potential to cause interference in multiple system installations. If you are experiencing an overload, turn off the receiver to see if it is causing interference with other components.
The numerical channel select button also turns red to indicate interference.
If the transmitter is more than 6 to 60 m (20 to 200 ft) from the receiver antenna, you may be able to increase range by doing one of the following:
If you see the red RF LED on a receiver, try the following:
The Antenna Fault red LED indicates a short circuit condition or excessive load at an antenna port.
