The Automatic Shutdown Interface displays shutdown time, which is divided into 5 options that are
5 min, 10min, 15min, 20min and Never (deactivating automatic shutdown). Press the Function
key to switch among each option and press the Scan button to save the setting. Note that the
selection of “Never” can’t be saved permanently taking into account the risk of battery
consumption. When the device is restarted, the shutdown time will resume to the last non-Never
time.
After the setting is completed, if there is no operation within the setting time limits, the system
automatically shuts down the OLED screen, thereby improving the continuous working time of the
device.

“Never” is selected, the screen time of “Never” can’t be saved permanently taking into account the
risk of battery consumption. When the device is restarted, the screen off time will resume to the
