Ends the Link between transmitter and receiver.
NO:
Preserves the Link between transmitter and
receiver.
Note: When a transmitter is unlinked, the channel
name reverts to Unlinked.
Troubleshooting
Input Overload
The Input Overload message indicates an excessive signal level at the transmitter
input. To prevent overload, reduce the gain setting.
No ShowLink Alert
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.
Firmware Updates
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: Tx > IR Presets > FW Update
ShowLink Test
Activates the ShowLink test 5-bar display. Measures
the remote control range of a ShowLink Access Point.
• 5 bars indicate the center of the coverage area
• 1 bar indicates the outer boundary of the
coverage area
• If bars are not displayed, ShowLink control is
not available
Firmware

Device ID
Identifies the transmitter on a linked receiver or in
WWB software.
• ID length can be up to 8 characters
• Use arrow buttons to scroll through characters
• Use set button to save and move to the next

Deeply Discharged Batteries
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 dis-
charged battery.
When the charger detects a deeply discharged battery, it automatically enters recov-
ery 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.
3
AA Type
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 car-
rier is installed.
RF PWR
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.
PCB Serial Number
Displays the serial number of the printed circuit board
(PCB) installed in the unit.
1. Enter the RF PWR menu by pressing and holding
the set button, and then pressing the ▼ button.
2. Press the ▲ button to access the serial number.
3. Momentarily press the power button to return to
