The transmitter is powered by a Shure lithium-ion rechargeable battery.
Caution: Turn off the transmitter before changing batteries.
Note: Refer to your battery charger manual for charging instructions.
Battery runtime varies according to the transmitter's operating mode. High power settings will reduce battery runtime.
Remaining battery runtime is shown on the display in hours and minutes (accurate to within 15 minutes).
The times shown in the table represent a battery with a minimum of 5 charge cycles, fully charged, at 100% health.
|RF Power (mW)||Runtime ShowLink Enabled (hours/minutes)||Runtime Without ShowLink (hours/minutes)|
The main menu screen displays the following transmitter parameters:
|① Channel Name||
Linked: Displays Linked receiver channel name
Unlinked: Not Linked to a receiver, channel name reverts to <unlinked>
|② Frequency||Tuned frequency of the transmitter|
|③ Battery Charge Indicator||5-segment icon indicates battery life|
|④ Remaining Battery Life||Displays remaining battery life in hours and minutes When Talk Switch mode is enabled, the word Talk is displayed when the power button is pushed Displays battery fault codes|
|⑤ ShowLink Icon||Indicates remote control of transmitter via ShowLink is possible|
|⑥ Audio Meter||Indicates the audio signal level|
|⑦ Control Lock Icon||Displayed when buttons are locked.
Note: The lock color will appear inverted when Hardlock: power only is enabled.
Lock the buttons of the transmitter to prevent accidental or unauthorized parameter changes.
Press and hold the ▼ and ▲ buttons for 2 seconds to lock. Repeat to unlock.
Power-on RF mute prevents transmission of audio when powering on the transmitter.
With the transmitter turned off, press and hold both the ▼ button and the SET button, and then press and hold the Power button.
After power-on, an RF Muted message indicates that the transmitter is in RF Mute mode and the power indicator LED will pulse.
Note: RF Mute mode persists through power cycles of the transmitter.
The Hardlock switch, located inside the battery compartment, provides an extra level of security against accidental or unauthorized changes.
Two Hardlock functionality options are available:
The transmitter will automatically power on (Auto Power Mode) with the selected lock option enabled.
Important: Use the transmitter power switch to turn on the transmitter the first time Auto Power Mode is enabled to initialize the feature.
An icon indicating the selected Hardlock option is displayed on the screen of the transmitter and receiver:
|Hardlock: all buttons|
|Hardlock: power only|
Tip: When using the Hardlock: power only option, simultaneously pressing the ▲▼ buttons will lock or unlock the control buttons.
To unlock the Hardlock:
Remove the battery and set the Hardlock switch to the unlocked position.
Use the arrow buttons to access the following parameter menus.

Displays the installed firmware version.
Identifies the transmitter on a linked receiver or in WWB software.
This setting ensures accurate battery metering when using the optional AA battery carrier. Set the battery type to Alkaline, NiMH, or Lithium.
Note: Menu not displayed unless an AA battery carrier is installed.
Sets RF power level. Access this menu by pressing and holding the set button and then pressing the ▼ button.
Use lower power settings to conserve battery life and to prevent RF overload at the receiver.
Note: A password is required in some regions.
The Power Button Function provides two modes of operation:
Displays the serial number of the printed circuit board (PCB) installed in the unit.
The IR Sync function forms a Link and sets the frequency between the transmitter and an AXT400 Receiver.
Two AXT100 transmitters can be connected to 2 lavalier microphones using an AXT652 "Y" cable to operate in Frequency Diversity mode with an AXT400 Receiver.
The Input Overload message indicates an excessive signal level at the transmitter input. To prevent overload, reduce the gain setting.
This alert appears when frequency is edited on a linked transmitter that is beyond the range of an active ShowLink access point. Choose OK to unlink the transmitter and complete the frequency change, or Cancel to return to the home screen.
Deep discharge occurs when a battery is discharged to less than 3.0 volts. The battery chargers have a recovery mode designed to restore charge to a deeply discharged battery.
When the charger detects a deeply discharged battery, it automatically enters recovery mode which supplies reduced current to the battery for up to 30 minutes.
If recovery is successful, the charger will exit recovery mode and charge the battery to capacity. If the battery cannot be recharged, charging stops and the battery must be replaced.

Firmware is embedded software used to control features and the user interface. Periodically, new versions of firmware are available for download from www.shure.com/wwb to incorporate additional features and enhancements. New versions of the firmware can be downloaded to AXT400 Receiver using the Firmware Update Manager tool available in WWB6 software and installed on the transmitter using the infrared ports on the transmitter and receiver.
To access the AXT400 receiver firmware update menu:
In an audio system containing both AXT400 and UR4 receivers, the overall system audio gain at the XLR (line) output varies depending on the receiver model and the type of transmitter.
The table below offers a comparison of the output gain at the XLR output for AXT400 and UR4 receivers for each transmitter model. Use the information in the table to achieve consistent gain levels when using systems comprised of both Axient series and UR series components.
