Tone Generator
The transmitter contains an internal tone generator that produces a continuous
audio signal. The tone is helpful when conducting a sound check or for trouble-
shooting 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.
1. From the Audio menu select Tone Gen.
2. Set the frequency to 400 Hz or 1000 Hz.
3. Select Level and use the arrow buttons ad-
just 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 Mic Offset
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 differ-
ences between transmitters. If using a single transmitter, set Offset to 0 dB.
1. Turn on the first transmitter and perform a sound check to test
the audio level. Turn off the transmitter when finished.
2. Turn on the second transmitter and perform a sound check to
test the audio level. Repeat for any additional transmitters.
3. If there is an audible difference in the sound level between the transmit-
ters, navigate to the Offset menu (Audio > Offset) in the transmitter to
increase or decrease the Offset in realtime to match the audio levels.

ShowLink Test
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 addi-
tional access points to extend coverage.
To activate the ShowLink Test:
1. From the Utilities menu, navigate to SL Test.
2. Press the O button to start the test and walk the transmitter around
the coverage area. Monitor the number of bars displayed and
the state of the ShowLink icon. Coverage boundaries are indi-
cated by 0 bars displayed or the ShowLink icon is empty.
3. Press the X button to exit the ShowLink test.
Tip: During a ShowLink test, press O (enter) to drop a marker in Wireless
Workbench.

Updating Firmware

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. 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 (in-
cluding transmitters), must have the same MAJOR and MINOR firmware ver-
sion numbers (e.g., 1.2.x).
Updating the Transmitter
1. Download the firmware to the receiver.
2. Access the following menu from the receiver:
Device Configuration > Tx Firmware Update.
3. 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.
4. Press ENTER on the receiver to begin the download to the transmitter.
The receiver will display the progress of the update as a percentage.
