Input Overload
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 Audio > Pad and select -12 dB.

Tone Generator
The transmitter contains an internal tone generator that produces a contin-
uous audio signal. The tone is helpful when conducting a sound check or
for troubleshooting the audio signal chain. The level of the tone is adjust-
able 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 trans-
mitter power.

Matching Audio Levels with Mic Offset
When linking two or more transmitters to a receiver, there may be a differ-
ence 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.
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 be-
tween 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.

ShowLink Test
The ShowLink Test is a tool to find the boundaries of the ShowLink cover-
age area. When the ShowLink test is activated, a five-bar display indicat-
ing 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:
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 function-
ality. Periodically, new versions of firmware are developed to incorporate
additional features and enhancements. To take advantage of design im-
provements, 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 consis-
tent 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
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 re-
ceiver. IR ports must be aligned for the entire down-
load, 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.
