The Taqt One includes an LED located in the upper right corner of its front panel. It displays two colors: green and red.

This LED is used to indicate several things:

• Connectivity status when sending a message
• NFC activation
• Terminal firmware update (FOTA)

Connectivity Status When Sending a Message

• Flashing green LED, once per second: Searching for a network.
• Flashing red LED, once per second: First network search attempt failed.
• Flashing green LED, once every 3 seconds: Network established, waiting for the data session to activate (Note: This step may last only a short moment).
• Rapidly flashing green LED, three times per second: Network connected, server communication in progress.

NFC Activation

Pressing a button to activate NFC is required. By default, the activation time is 5 seconds.

• If NFC is successfully activated: The LED flashes very quickly and briefly in green, then slowly flashes red (once per second) throughout the tag listening period (default is 5 seconds).
• If NFC activation fails: The LED flashes very quickly in red, and the buzzer emits beeps simultaneously (this step lasts less than 2 seconds).

Terminal Firmware Update (FOTA)

When the terminal is in the process of updating to a new firmware, the LED alternates colors, flashing slowly in green and red.
