Overview
Battery Low Indicator
When the battery charge level is too low to sustain continuous operation, the LCD flashes "Battery Low".
If not recharged, the LCD will flash again, and then the device shuts down to prevent a total discharge of the
battery.
To recharge the battery, insert the Mio R-3 into the Mio Remote Charging Base (see the Mio Remote Charging
Base section on page 25).
