Red (solid)	Charging
Amber (flashing)	Out of temperature range, or battery error
Off	Power supply is disconnected, or no device is docked in the charging bay

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 battery 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.

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

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 and 5.8 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 receivers 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 and 5.8 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.

System Set Up

Before beginning, turn off all receivers and transmitters. Turn on and link each receiver/transmitter pair one at a time to prevent cross-linking.

1. Turn on a receiver.
2. Press and hold the group button to select a group (if necessary). If the group is already set, press the channel button to scan for the best available channel.
3. Turn on a transmitter. The blue RF LED will flash while the transmitter and receiver form a link. When the link has successfully formed, the RF LED will remain illuminated. The transmitter and receiver will remain linked for future usage.

Repeat steps 1-3 for each additional receiver and transmitter. Remember to set each receiver to the same group.
Note: Dashes appearing on the group and channel display after a channel selection indicate that frequencies are not available in the selected group. Choose a group that supports more receivers and repeat the linking steps.

Manually Linking Receivers and Transmitters

1. Turn on a transmitter.
2. Press and hold the link button on the transmitter until the LED begins to flash green.
3. Press and hold the link button on the receiver. The blue RF LED will flash and then remain illuminated when the link has been established.
4. Test the audio to verify the link.

Linking Two Transmitters to a Receiver

Only one transmitter can be active at a time to prevent cross interference. Gain settings for each transmitter can be independently set and stored when the transmitter is active.

Do not turn on and operate both linked transmitters at any time. Turn off both transmitters before beginning.

1. Press the group button to select a group. The receiver automatically scans the selected group to find the best available channel.
2. Turn on transmitter 1 and link it to the receiver. Adjust the gain, and then turn off the transmitter.
3. Turn on transmitter 2 and press and hold the link button on the transmitter and the receiver to link them together. Adjust the gain, and then turn off the transmitter.

Identifying Linked Transmitters and Receivers with Remote ID

Use the remote ID feature to identify linked transmitter and receiver pairs in multiple receiver systems.
To activate remote ID:

1. Momentarily press the link button on the transmitter or receiver.
2. The screen of the linked receiver will blink and display ID, while the status LED on the linked transmitter will flash red/ green.
3. To exit remote ID mode, momentarily press the link button or allow the function to timeout.

Multiple Receiver Systems

To run more than two receivers at the same time, the GLX-D+ frequency manager is recommended to improve RF reliability (only compatible with GLXD4R+).
However, you can run multiple receivers without the frequency manager. Select the group by determining the total number of receivers in your system. All receivers in the system must be set to the same group.

2.4 GHz and 5.8 GHz bands:

Group	Number of Receivers	Description
1	2 - 5 typical	Default setting
2	2 - 5 typical	Best multi-channel group if you experience interference
3	1	Best single-channel group if you experience interference
A*	Up to 11 typical, 16 maxi mum	Default setting
B*		Best multi-channel group if you experience interference

2.4 GHz bands only:

Group	Number of Receivers	Description
1	2 - 4 typical	Default setting
2	2 - 4 typical	Best multi-channel group if you experience interference
3	2 - 4 typical, 8 maximum	Only use Group 3 in controlled Wi Fi environments because there are no back up frequencies to avoid interference
4	1	Best single-channel group if you experience interference
A*	Up to 9 typical, 11 maximum	Default setting
B*		Best multi-channel group if you experience interference

*Groups A and B are only for systems with a GLXD4R+ and GLXD+ frequency manager.
See Tips to Improve Wireless System Performance for additional information. See the GLXD+FM user guide for information about receiver groups when connected to the GLX-D+ frequency manager.
