Important Tips for Care and Storage of Shure Recharge-
able 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 transmitter­to­antenna dis­
tance and connect to antenna splitter
Coexisting with Wi-Fi
If you plan to use Wi­Fi during a performance, turn on Wi­Fi devices prior to turning on GLX­D and scanning for the best chan­
nel. GLX­D detects and avoids other Wi­Fi traffic by scanning the entire 2.4 GHz environment and selecting the three best fre­
quencies to transmit on. This method avoids Wi-Fi signals and results in reliable performance for your GLX-D wireless system.
“Bursting” Wi­Fi is harder to detect as it is periodic; however, because GLX­D only repeats the most important information,
even bursts at very high levels don’t have an effect on your audio performance.
