## Hands-Free Opening

Select Hands-Free as the unlock mode in the SmartPlus App.

In this mode, users can unlock the door automatically when approaching the door phone. The actual behavior depends on both the device configuration and hardware capabilities.

| Yes | No | The user must wave a hand near the device to open the door. |
| No | Yes | The door opens automatically when the user approaches the device. |
