the same as you disconnect and reconnect the power adaptor to the switcher. To reseting the device follow
the steps: #reset #reboot#restart
Step 1. Push the button with a thin object for a second.
Step 2. Wait until the device reboots. You can use the switcher when the LIVE LED is blinking slowly again.

ATTENTION! Reseting the device does not reset the settings to factory defaults. To reset factory default
settings see the previous section.
2.4.7. Entering Firmware Upgrade Mode
It may happen that the firmware upgrade process is not successful and the device cannot be switched to
bootload mode automatically. In this case, switcher device can be forced into firmware upgrade mode as
follows: #bootload

Step 2. Press and keep pressed the Show Me button.
Step 3. Power on the switcher while the Show Me button is being pressed. If the device is switched to firmware
upgrade mode the LIVE LED is blinking quickly (less than 500 ms duty cycle). The other LEDs are off.
