Using emergency button

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

Use a paper clip or a tiny screwdriver to push the emergency button. Hold the button pressed for more than 5 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 short series of beeps with a longer pause between them. The action is selected by releasing the button in the pause. Once the beep count reaches selectable maximum it starts over again from 1. To cancel any selection unplug the power cable and release the button.
1 beep - do a set default configuration
4 beeps - do the emergency reload - reset configuration to default and start emergency update
5 beeps - set network configuration to use DHCP server
6 beeps - push update expected, do not try to connect to the server for update
After the action is selected it is processed and the terminal is rebooted after that
