Daily Use 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.
