EM-129
NOVATEK-ELECTRO
Status condition indication:
• Blue (flashes) - connects to a Wi-Fi access point;
• Blue (on) - the load is on, there is a connection to Wi-Fi;
• Blue (flashes once every 5 seconds) - the load is off, there is a connection to Wi-Fi;
• Red flashes) - the countdown of the re-closure time is in progress;
• Red (on) – a failure or the device is blocked due to a failure;
• Blue - red (flashing) - Wi-Fi connection setup mode is on;
• Purple - the settings are reset to the factory settings, the embedded software is updated, or the Wi-Fi control button
is pressed.
