Batteries and Charging
GLX-D transmitters are powered by Shure SB902 lithium-ion rechargeable batteries. Advanced battery chemistry maximizes runtimes with zero memory
effects, eliminating the need to discharge batteries prior to charging.
When not in use, recommended battery storage temperature is 10°C (50°F) to 25°C (77°F).
Note: The transmitter will not pass RF or audio signals when connected to the charging cable.
The following battery charging options are available:
Charging from an AC Power Source
1. Plug the charging cable
into the charging port
on the transmitter.
2. Plug the charging cable
into an AC power source.
LED Status During Charging
The following LED states indicate battery status when the transmitter is
connected to a charger:
• Green = charging complete
• Green Flashing = battery charge > 90%
• Red = battery charging
• Amber Flashing = battery error, replace battery
Installing Transmitter Batteries
Bodypack Transmitter
1. Move the locking lever to the open posi-
tion and slide the battery door open.
2. Place the battery into the transmitter.
3. Close the battery door and slide door to engage the latch.
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
Charging from a USB Port
1. Plug the USB charging
cable into the charging
port on the transmitter.
2. Plug the cable into a
standard USB port.
Charging Times and Transmitter Runtimes
Use the following table to determine approximate battery runtime based
on the duration of charging time. Times shown are in hours and minutes.
Note: Batteries charge faster when using an AC powered charger versus a USB
connection.
AC Power USB Connection
Source Charging Charging
0:15 0:30
0:30 1:00
1:00 2:00
3:00 4:00
*Storage time or excessive heat will reduce maximum runtime.
Note: GLX-D transmitters automatically power-off after approximately 1 hour to con-
serve battery life if the signal from a linked receiver is not detected.
Transmitter Battery Meter
The number of segments illuminated on the meter indicates the remaining
battery life for a linked transmitter:
① = > 30 min
② = > 2 hours
③ = > 4 hours
④ = > 6 hours
⑤ = > 8 hours
⑥ = > 10 hours
⑦ = > 12 hours
Note: The LEDs will cycle on/
off while battery life is being
calculated.
