Use this function if you want to restore your Yakumo deltaX 5 BT to the factory default state. Restoring factory default state means all data you have entered in RAM, including all files, system settings, and additional programs you have installed, will be erased.
AutoLock
You may not want any accidental touching of the buttons to turn on your device. This can happen when, for example, you put your device in a bag and something else in the bag presses against your device.
This AutoLock feature allows your device to be automatically locked whenever it turns off. Even if your device is accidentally turned on, a message will prompt you to unlock it within 5 seconds. As long as there is no response from you within 5 seconds, the device turns off again. This helps saving battery power
