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 = battery voltage at 3.8 volts.

The following indicators appear on the home screen next to each bay number:

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 buttons.
2. Navigate to the Storage Mode menu and press the SET button.
3. Use the arrow buttons to select Off.
4. Press the SET button 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
temperature is 0°C (10°F) to 25°C (77°F).

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 dis­ charged 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, Recovery Failed is displayed and charging stops.

Tip: Periodically charge batteries using the Storage Mode function to avoid deep discharge and to maintain the ideal battery a  torage voltage of 3.8 volts.

Firmware Updates

Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are devel­ oped 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 Wireless Workbench software.
Firmware is available for download from www.shure.com.
