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.
