CAUTION! Ensure that amplifier power remains on during a firmware update. Do not turn off the amplifier until the update is
complete.
The Shure Update Utility will find the latest versions of firmware. You can download the updates to your computer. Once the
download is complete, the amplifier automatically begins the firmware update, which overwrites the existing firmware.
1.
From Shure Update Utility software, click the Updates Available button.
2.
To download firmware to your computer (but not to devices), check the box next to the updates you want and select
Download.
3.
Connect the amplifier to your computer with the USB cable.
4.
From the amplifier menu, select UTILITIES > FIRMWARE > ENABLEFWUPDATE
Note: ENABLE FW UPDATE must be enabled in order for the firmware update to work.
5.
Confirm that you want to download the latest firmware to the amplifier.
Note: The battery should be charged before updating firmware. Do not attempt to update firmware if battery percentage is less than 10%.
Lithium-ion Rechargeable Batteries
Storing Batteries
To avoid degrading battery health, keep the storage temperature range between 10°C to 25°C (50°F to 77°F).
Battery Repair and Replacement
Lithiumion batteries have no “memory effect”, and instead experience a more linear reduction in capacity. Contact Shure Ser
vice and Repair to replace the battery if you experience any issues.
Using Earphones
Safely Connect and Disconnect Earphones
Connect to the amplifier: Align the red dot on the earphone cable connector with the red dot on the amplifier earphone out
put.
Disconnect from the amplifier: Pull the knurled connector collar up to safely release the lock on the earphone cable.

Choosing a Sleeve
Select an earphone sleeve that provides the best fit and sound isolation. It should be easy to insert, fit comfortably, and easy to
remove.
Soft Flex Sleeves: In small, medium, and large sizes. Made from pliable rubber.
Soft Foam Sleeves: Compress the foam sleeve between your fingers and insert into the ear canal.
Hold in place for about ten seconds while the foam expands.
Triple-Flange Sleeves: If desired, use scissors to trim the stem on the sleeve.
Wearing the Earphones
1.
Carefully insert the earphone into the ear like an earplug, so that a tight seal is formed.
Important: If there is a lack of low frequency response (bass), the earphone sleeve may not be forming a proper seal.
Gently push the earphone deeper into the ear canal or try using a a different sleeve.
Warning: Do not push the earphone sleeve beyond the ear canal opening.
2.
Wear earphone cables over the back of the ear to keep them in place during physical activity. Guide the cable down ei
ther the front or back of the body, and use the cable cinch to tighten up the remaining slack.
The fit of the earphone can greatly affect sound quality.
Changing Sleeves
•
Twist and pull to remove the sleeve from the nozzle.
•
Slide on a new sleeve so that it completely covers the barb and the nozzle.
14/21
Shure Incorporated
Caution: If the barb or any of the nozzle is exposed, the sleeve is not properly installed. Replace sleeves if they do not tightly grip the nozzle. To ensure proper
fit and performance, use only sleeves supplied by Shure (unless using custom molded sleeves).
Removing the Earphones
Grasp the body of earphone and gently twist to remove.
Note: Do not pull on cable to remove earphone.
Maintenance and Cleaning
Careful maintenance ensures a tight seal between the sleeve and nozzle, improving sound quality and product safety.
•
Keep the earphones and sleeves as clean and dry as possible.
15/21
Shure Incorporated
•
To clean sleeves, remove them from earphones, gently rinse in warm water and air dry. Foam sleeves require a longer
drying time. Inspect for damage and replace if necessary. Ear sleeves must be completely dry before reusing.
•
Wipe the earphones and sleeves with mild antiseptic to avoid infections. Do not use alcohol-based disinfectants.
•
Do not expose earphones to extreme temperatures.
•
Replace sleeves if they do not fit properly.
•
Do not attempt to modify this product. Doing so will void the warranty and could result in personal injury and/or product
failure.
Cleaning the Earphone Nozzle
If you notice a change in sound quality, remove the sleeve and check the nozzle of your earphone. If nozzle is blocked, clear
obstruction by using wire loop end of cleaning tool.
If no obstruction is found or if sound quality does not improve, replace the sleeve with a new sleeve.
Caution: When cleaning, do not force any object through the earphone nozzle! This will damage the earphone sound filter.
Warning: The cleaning tool is only to be used to clean the earphones. Any other use, such as using the tool to clean ears or foam sleeve, could result in injury.
The cable connectors to the earphones may collect debris or other deposits that can affect audio quality. If this happens, disconnect the cables and clean them
using a dry cotton swab.
