Important Tips for Care and Storage of Shure Rechargeable Batteries
Proper care and storage of Shure batteries results in reliable performance and ensures a long lifetime.
Always store batteries and transmitters at room temperature
Ideally, batteries should be charged to approximately 40% of capacity for long-term storage
During storage, check batteries every 6 months and recharge to 40% of capacity as needed
Important: Always fully charge a new battery before first use.
Multiple Receiver Systems
For ease of set up, frequencies are divided into groups to best match the channel requirements for your system.

Shure Incorporated

Frequencies Notes
1Up to 4 3 Initial factory setting.
2Up to 5* 3 Best multi-channel group if you experience interfer
ence.
3Up 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.
41 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.
Turn on the first receiver.
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.
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.
Turn on the transmitter: Within 5 seconds, press and hold the LINK button until the transmitter LED begins to flash
green.

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.
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.
Press the group button to select a group. The receiver automatically scans the selected group to find the best available
channel.
Turn on transmitter 1 and link it to the receiver. Adjust the gain, and then turn off the transmitter.
Turn on transmitter 2 and link it to the receiver. Adjust the gain, and then turn off the transmitter.
2.4 GHz Spectrum Overview
GLX-D operates within the 2.4GHz ISM band which is utilized by Wi-Fi, Bluetooth, and other wireless devices. The benefit of
2.4GHz is that it’s a global band that can be used anywhere in the world, license free.
Overcoming the Challenges of 2.4GHz
The challenge of 2.4GHz is that Wi-Fi traffic can be unpredictable. GLX-D meets these challenges in the following ways:
Prioritizes and transmits on the best 3 frequencies per channel (choosing from a pool of 6 frequencies across the 2.4GHz
band)
Repeats the most important information such that one frequency can be taken out entirely without audio interruption
Continuously scans during usage to rank all frequencies (both current and backup frequencies)
Seamlessly moves away from interference to backup frequencies without audio interruption
Coexisting with Wi-Fi
If you plan to use WiFi during a performance, turn on WiFi devices prior to turning on GLXD and scanning for the best chan
nel. GLXD detects and avoids other WiFi traffic by scanning the entire 2.4GHz environment and selecting the 3 best frequen
cies to transmit on. The result of this is reliable performance for your GLXD wireless system as well as avoiding WiFi trans
missions which may be important as well.
“Bursting” WiFi is harder to detect as it is periodic; however, because GLXD repeats the most important information, even
bursts at very highlevels don’t have an effect on your audio performance.
Challenging Wireless Environments
Some environments are more difficult than others for 2.4 GHz wireless system performance. Additionally, body absorption has
a greater impact in the 2.4 GHz spectrum, compared to the UHF spectrum. The simplest solution in many cases is to reduce
the transmitter to receiver distance such as placing the receivers on the stage with a clear line of sight.

Challenging environments include:
Areas with few reflective surfaces such as:
Outdoors
Buildings with very high ceilings
3 or more GLX-D receivers in use
Strong Wi-Fi presence
Competitive 2.4 GHz systems in use
Note: Unlike analog TV band wireless which typically uses the same type of transmissions across manufacturers, all 2.4GHz wireless currently on the market
use different variations of wireless transmission. These differences make it more difficult to mix and match 2.4 GHz from multiple manufacturers successfully,
as can be done with TV band wireless solutions.
Tips and Methods to Improve Wireless System Perfor-
mance
If you encounter interference or dropouts, try the following suggestions:
Scan for the best available channel (press the channel button).
Reduce transmitter to receiver distance  for example, place receivers on stage with a line of sight to the front of the re
ceiver.
Change the group for all GLX-D systems:
Single-Chanel System: use Group 4, which is optimized for single-channel use
Multi-Channel System: use Group 2, which is the most robust wireless group
Move receiver further away from WiFi access points, computers, or other active 2.4 GHz sources. Recommended dis
tance is a minimum of 3 meters (10 feet).
Disable non-critical Wi-Fi on computers, cell phones, and other portable devices
If you plan to use WiFi during a performance, turn on WiFi prior to turning on GLXD and scanning for the best chan
nel.
Keep the transmitter and receiver more than 2 meters (6 feet) apart
Avoid heavy Wi-Fi traffic activities such as downloading large files or viewing a movie.
Locate competitive 2.4 GHz receivers away from each other
Avoid placing transmitter and receiver where metal or other dense materials may be present
Move the receiver to the top of the equipment rack
Keep transmitters more than 2 meters (6 feet) apart - this is less critical at shorter receiver to transmitter distances
Note: If transmitters are within 6 inches of non-GLXD transmitters or microphone cartridges, audible noise is possible.
During sound check, mark trouble spots and ask presenters or performers to avoid those areas
If there is a known strong source of Wi-Fi and you specifically want to use frequencies within that Wi-Fi channel, use the
following Group/Channel of GLX-D (best option listed first):
Wi-Fi 1: Group 3/Channel 8, Group 3/Channel 4
Wi-Fi 6: Group 3/Channel 7, Group 3/Channel 5
Wi-Fi 11: Group 3/Channel 2, Group 3/Channel 1
