Using the Emergency Button

The correct procedure for using the emergency button is the following:

  • Use a paper clip or a tiny screwdriver to push the emergency button in. Hold the button pressed for more than five seconds.

  • Alternatively, you can unplug the terminal power cable, hold the emergency button, and plug the terminal power back while still holding the emergency button.

  • The terminal now starts with a short series of beeps with a longer pause between them. The action is selected by releasing the button during the pause. Once the beep count reaches the selectable maximum, it starts again from one. To cancel any selection, unplug the power cable and release the button.

  • One beep – do a set default configuration.

  • Four beeps – do the emergency reload – reset the configuration to default and start an emergency update.

  • Five beeps – set the network configuration to use a DHCP server.

  • Six beeps – push update expected, do not try to connect to the server for updating.

  • After the action is selected, it is processed, and the terminal is rebooted after that.
