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
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 2.4 GHz
The challenge of 2.4 GHz is that Wi-Fi traffic can be unpredictable. GLX-D
meets these challenges in the following ways:
• Prioritizes and transmits on the best three frequencies per channel
(choosing from a pool of six frequencies across the 2.4 GHz band)
• Seamlessly moves away from interference to backup frequencies without audio interruption
• Optional GLX-D Frequency Manager improves RF reliability for systems
with more than two receivers
• Continuously scans during usage to rank all frequencies (both current
and backup frequencies)
• Antenna mounting accessories and directional antennas (available
separately) help reduce transmitter-to-antenna distance and connect to
antenna splitter
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 channel. GLX-D detects
and avoids other Wi-Fi traffic by scanning the entire 2.4 GHz environment
and selecting the three best frequencies to transmit on. This method
avoids Wi-Fi signals and results in reliable performance for your GLX-D
wireless system.
“Bursting” Wi-Fi is harder to detect as it is periodic; however, because
GLX-D only 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 transmitter-to-receiver distance by placing
receivers on the stage with a clear line of sight. You can also mount antennas remotely using Shure directional antennas to reduce transmitter-to-antenna distance.
Challenging environments include:
• Areas with few reflective surfaces such as:
- Outdoors
- Buildings with very high ceilings
• Three or more GLXD4R receivers in use and not connected to a GLX-D
Frequency Manager
• Areas with a strong Wi-Fi presence
• 2.4 GHz systems from other manufacturers in use
Note: Unlike analog TV band wireless system which typically use the
same type of transmissions across manufacturers, all 2.4 GHz wireless
currently on the market use different variations of wireless transmission.
These differences make it more difficult to mix and match 2.4 GHz systems from multiple manufacturers, as can be done with TV band wireless
solutions.

Tips to Improve Wireless System Performance
If you encounter interference or dropouts, try the following suggestions:
1. Place receiver at least 3 meters (10 feet) away from Wi-Fi access points, computers, or other active 2.4 GHz sources.
- Avoid heavy Wi-Fi traffic activities such as downloading large files or viewing a movie.
- Turn on any Wi-Fi prior to turning on GLX-D and scanning for the best channel.
2. Reduce transmitter-to-receiver distance by placing receivers on stage or above the audience with a clear line of sight to the transmitter.
- Move receiver to the top of the equipment rack for a clear line of sight.
- Mount antennas remotely to place closer to transmitters and improve RF reliability if receivers cannot be moved closer.
- Make sure people do not block the line of sight between receiver and transmitter.
Additional Tips
• Do not place competitive 2.4 GHz receivers near GLXD4R receivers.
• Connect more than two GLXD4R receivers to a GLX-D Frequency Manager to improve RF reliability.
• Scan for the best available channel by pressing the channel button.
• Keep transmitters more than 2 meters (6 feet) apart. This is less critical with shorter receiver-to-transmitter distances or if receivers are connected to a
GLX-D Frequency Manager.
Note: If transmitters are within 6 inches of non-GLX-D transmitters or microphone cartridges, audible noise is possible.
• Move transmitter and receiver away from metal or other dense materials.
• During sound check, mark trouble spots and ask performers to avoid those areas.
• If there is a strong source of Wi-Fi and you specifically want to use frequencies within that Wi-Fi channel, use the following Group/Channel combinations (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
Remote Antenna Placement
Follow these guidelines when mounting antennas remotely:
• Reduce distance between transmitter and antenna.
• Mount antennas farther from each other to improve performance.
• Position antennas so there is nothing obstructing the line of sight to the transmitter, including the audience.
• Keep antennas away from metal objects and any other antennas.
• Use only low-loss reverse SMA cable to avoid poor RF signal.
- Consult cable's specifications and calculate signal loss for desired cable run.
• Use one continuous length of cable from the antenna to the receiver to increase signal reliability.
• Always perform a walk-around test to verify coverage before using a wireless system during a speech or performance. Experiment with antenna
placement to find the optimum location. If necessary, mark any trouble spots and ask presenters or performers to avoid those areas.

Multiple Receiver Systems
Combo Systems
To run more than two receivers at the same time, the GLX-D Frequency
Manager is recommended to improve RF reliability.
However, you can run multiple receivers without the frequency manager.
Select the group by determining the total number of receivers in your system (channel count). All receivers in the system must be set to the same
group.
Channel
Group
1 Up to 4 3 Initial factory setting.
2 Up to 5* 3 Best multi-channel
3 Up to 8* 0 Only use Group 3 in
4 1 27 Best single-channel
*Environmentally dependent, 4 systems typical
See "Tips to Improve Wireless System Performance" section for additional
information. For information about receiver groups when connected to the
