### **Network Settings Reset Options**

To erase stored network settings (e.g., Wi-Fi connection, client/AP mode, IP address, etc.), press and hold buttons **3 + 4 + 5 + 6** for several seconds (approximately 5–10 seconds). After this action, the device will return to its default network mode—typically activating its own **Access Point (AP)**, which can be used to reconfigure the settings.

***

### **Enable / Disable Access Point (AP) Mode**

To manually enable or disable Wi-Fi Access Point mode, press and hold buttons **7 + 8** for approximately 3–5 seconds. In AP mode, the device broadcasts its own Wi-Fi network, allowing connection for configuration. Turning off the AP mode switches the device to **Client Mode**, where it expects to connect to a previously known Wi-Fi network.
