For ease of set up, available frequencies are divided into three groups based on the number of receivers supported. All receivers in the system must be set to the same group. To select a group, determine the total number of receivers in the system (channel count), and then select the appropriate group. Note: To maximize the number of receivers on-air, Group 3 does not offer backup frequencies. Group 3 should only be used in controlled Wi-Fi environments to prevent interference from unexpected Wi-

Fi devices. Group 1 2 3 Initial Factory Setting. Best Group to use if you experience interference. Only use Group 3 in controlled Wi-Fi environments because there are no backup frequencies to avoid interference. Backup Frequencies Available? Notes Yes Yes No Channel Count Up to 4 Up to 5 Up to 8 Note: If you experience interference, reduce transmitter to receiver distance and set all GLX-D systems to group 2, which is the most robust wireless group. See "Tips to Improve Wireless System Performance" section for additional steps if needed. Setting Up Receivers and Transmitters Note: Before beginning, turn off all receivers and transmitters. Turn on and set up each receiver/transmitter pair individually to prevent cross-linking. 1. Turn on the first receiver. 2. Press and hold the group button to select a group (if necessary) or if the group is already set, press the channel button to scan for the best available channel. 3. Turn on the first transmitter. The blue RF light will illuminate when a link is established. 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 during a channel scan indicate that frequencies are not available in the selected group. Choose a group that supports more receivers and repeat the set up steps. Manually Selecting a Group and Channel Specific groups and channels can be assigned to the receiver instead of using the automatic scan function. Note: Group 3 should only be used in controlled Wi-Fi environments to prevent interference from unexpected Wi-Fi devices. Selecting a Group 1. Press and hold the group button for 2 seconds until the group display flashes. 2. Press the group button to scroll through the available groups. 3. The receiver will automatically save the selected group. Selecting a Channel 1. Press and hold the channel button for 2 seconds until the channel display flashes. 2. Press the channel button to scroll through the available channels. 3. The receiver will automatically save the selected channel. Note: A double dash symbol-- displayed on the receiver screen during a channel scan indicates that there are no available channels within the selected group. Choose a group with more channels and repeat set up steps. Manually Linking a Transmitter to a Receiver Use the manual linking option to change the transmitter linked to a receiver. For example, changing the linked transmitter from a bodypack to a handheld. Use the following steps to manually change the transmitter linked to a receiver:

1. Turn on the transmitter: Within 5 seconds, press and hold the LINK button until the transmitter LED begins to flash green. 2. Press and hold the link button on the receiver: The blue rf LED will flash, and then remain on when the link has been established. 3. Test the audio to verify the link and adjust the gain if necessary. 8 DRAFT 3.4.13 2.4 GHz Spectrum Overview GLX-D operates within the 2.4GHz ISM band which is utilized by for Wi-Fi, Bluetooth, and other wireless. The benefit of 2.4GHz is that its one global band that can be used anywhere in the world, license free. Overcoming the Challenges of 2.4GHz The challenge of 2.4GHz is that Wi-Fi traffic can be unpredictable. GLX-D meets these challenges in the following ways:

Prioritizes and transmits on the best 3 frequencies per channel (choosing from a pool of 6 frequencies across the 2.4GHz band) Repeats the most important information such that one frequency can be taken out entirely without audio interruption Continuously scans during usage to rank all frequencies (both current and backup frequencies) Seamlessly moves away from interference to backup frequencies without audio interruption Coexisting with Wi-Fi GLX-D avoids continuous Wi-Fi traffic by scanning the entire 2.4GHz environment and selecting the 3 best frequencies to transmit on. The result of this is reliable performance for your GLX-D wireless system as well as avoiding Wi-Fi transmissions which may be important as well. Bursting Wi-Fi is harder to detect as it is periodic; however, because GLX-D repeats the most important information even if these bursts are very high-level, they dont have an effect on your audio performance. Challenging Wireless Environments Some environments are more difficult than others for 2.4 GHz wireless system performance. The simplest solution in many cases is to reduce the transmitter to receiver distance such as placing the receivers on the stage with a clear line of sight. Challenging environments include:

Outdoors Very high ceilings 3 or more GLX-D receivers in use Strong Wi-Fi presence Non-Shure 2.4 GHz systems in use Tips to Improve Wireless System Performance If you encounter interference or dropouts, try the following suggestions:

Scan for the best available channel (press the channel button) Reposition the receiver so there is nothing obstructing a line of sight to the transmitter (including the audience) Keep the transmitter and receiver more than 2 meters (6 feet) apart Keep transmitter to receiver distance within 60 meters (200 feet) -

place receivers on-stage within line of sight if possible Remove or relocate nearby sources of wireless interference, such as Wi-Fi devices or hotspots, cell phones, two-way radios, computers, media players, and digital signal processors Disable non-essential Wi-Fi/bluetooth devices and avoid heavy Wi-Fi traffic activities such as downloading large files or viewing a movie. Locate GLX-D receivers away from non-Shure 2.4 GHz receivers Avoid placing transmitter and receiver where metal or other dense materials may be present Recharge or replace the transmitter battery Keep transmitters more than 2 meters (6 feet) apart Note: GLX-D transmitters closer than 6 inches (15 cm) to other non-GLX-D transmitters may cause audible noise in that transmitter During sound check, mark trouble spots and ask presenters or performers to avoid those areas 2.4 GHz Frequency Tables The following table lists receiver frequencies, channels, and latency for each group:

Group 1: Channels 1-4 (latency = 3.9 ms) 1/1 2424 2425 2442 2443 2462 2464 Group 2: Channels 1-5 (latency = 7.3 ms) 2/5 2/1 2437 2423 2438 2424 2443 2462 2463 2444 2477 2473 2474 2478 1/3 2411 2413 2430 2431 2476 2477 1/2 2418 2419 2448 2450 2469 2471 1/4 2405 2406 2436 2437 2455 2457 2/2 2404 2405 2426 2427 2456 2457 2/3 2417 2418 2451 2452 2468 2469 2/4 2417 2418 2451 2452 2468 2469 Group 3: Channels 1-6 (latency = 7.3 ms) 3/5 3/1 2409 2415 2451 2416 2443 2452 3/2 2422 2423 2439 3/3 2426 2427 2457 3/4 2447 2448 2468 3/6 2431 2462 2463 9 DRAFT 3.4.13 Receiver Operation Audio Gain Adjustment Transmitter gain has an adjustment range from -20 dB to +40 dB, in 1 dB increments.
