This feature is only available on the Nano S running 1.3.1 firmware and more recent firmwares.
If the Auto-Lock feature is activated, your Nano S will enter into stand-by mode after a delay you can choose (1, 3, 5 or 10 minutes). Then, each time your Nano S will be connected and not used during this selected delay, it will run stand-by mode. When you want to use again your device, you will have to press both buttons and re-enter your PIN code.
- Open the "Settings" of the Nano S
- Select "Security"
- Select "Auto-lock"
- Scroll to choose your favourite delay and press both buttons to validate or select OFF if you do not want to set this mode
