Batteries and Charging
GLX-D+ transmitters are powered by Shure SB904 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
Plug the charging cable into the charging port on the transmitter.
Plug the charging cable into an AC power source.
Charging Status LEDs
LED Color Description
Green (solid) Device is fully charged

Charging Times and Transmitter Runtimes
Use the following table to determine approximate battery runtime based on the duration of charging time when in 5.8 GHz
mode. Times shown are in hours and minutes. Transmitters automatically poweroff after approximately 1 hour to conserve bat
tery life if the signal from a linked receiver is not detected.
Receiver Bay or AC Power Source Charging Transmitter Runtime
0:15 up to 1:30
0:30 up to 3:00
1:00 up to 6:00
3:00 up to 11:30*
*Storage time or excessive heat will reduce maximum runtime.
Note: If receiver is powered off and remains plugged in, battery will continue charging.
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= > 11.5 hours
Note: The LEDs will cycle on/off while battery life is being calculated.
