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.
Parameter Menus
Use the arrow buttons to access the following parameter menus.
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
