Quick Start
To reduce set up time, the transmitter and receiver automatically link to form an audio channel the first time they are powered
on and never have to be linked again.
Note: If using multiple effects pedals, place the receiver pedal first in the signal chain.
Step ① Connect power supply to the receiver and plug the power cord into an AC power source.
Step ② Connect the transmitter to the instrument and turn on the transmitter.
Connect receiver audio output to an amplifier or mixer. Turn on the receiver: The blue rf LED
will flash while the transmitter and receiver form a link. When the link has successfully
Step ③
formed, the rf LED will remain illuminated.
Note: The transmitter and receiver will remain linked for future usage. At power-up, the blue rf LED will illuminate,
skipping the linking step.
Step ④ Check the audio and adjust the gain if necessary.

Batteries and Charging
GLX-D transmitters are powered by Shure SB902A 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.

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
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.
