Range Extender Power Path Selection
During normal operation, the range extender is powered by the integrated AC power supply. The BBU
enters discharge mode and begins providing power to the range extender when the AC power is
interrupted outside a range of 85V to 250V for more than 20 ms. The BBU charges or discharges only;
it does not support both simultaneously.
