Low Power Detection
1. The device works properly, when the voltage
is higher than 3.6V;
2. When the voltage is among 3.4V to 3.5V,
the transceiver receives normally but with alerts and
“dididi” indication every 20secs, and launches
normally, but the light flashes red while launching.
3. When the voltage is below 3.3V, then the
transceiver will power off by itself.
