Recovering a Battery from Deep Discharge
A deeply discharged battery is one that has been discharged to less than 3.0 volts. When the charger detects a deeply discharged battery, it automatically enters recovery
mode, which charges the battery using a reduced current. The Recovery icon is displayed next to the bay number on the home screen. If recovery is successful, the charger
exits recovery mode and charges the battery to capacity. If the battery cannot be recovered in less than 30 minutes, an error message is displayed and charging stops.
Storage Mode
When set to storage mode (Storage Mode = Store at 3.8 V), all batteries are
charged or discharged to 3.8 volts, which is ideal for long-term storage.
The charge status LEDs indicate the voltage state:
• Red flashing = battery charging or discharging to 3.8 volts.
• Amber flashing = battery voltage at 3.8 volts.
Charging or discharging may take several hours. The remaining time is displayed as
Time to 3.8 V in the battery monitoring menu (instead of Time to Full).
To exit storage mode:
1. Enter the utility menu by holding both arrow keys.
2. Navigate to the Storage Mode menu and press the SET key.
3. Use the arrow keys to select Off.
4. Press the SET key to exit.
When batteries are ready for storage, they should be removed from the charger and
placed into a temperature controlled area. Recommended battery storage tempera-
ture is 0°C (10°F) to 25°C (77°F).
Firmware Updates
Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are developed to incorporate additional features and
enhancements. To take advantage of design improvements, new versions of the firmware can be uploaded and installed using the Firmware Update Manager tool available in
WWB6 software. Firmware is available for download from http://www.shure.com.
