Battery Saving Mode
If the Mobile WiFi has been inactive for some time, the Mobile WiFi enters the standby mode,
in which the power indicator blinks slowly and the other indicators are off. Pressing the power
button causes the indicator to light up.
When the Mobile WiFi is being powered only by the battery, you can choose to enable or
disable the automatic Wi-Fi turnoff function. If this function is enabled and if no Wi-Fi devices
access the Mobile WiFi for a period of time, the Wi-Fi turns off automatically. You can press the
power button to turn the Wi-Fi on again.
