When performing a firmware update, do NOT press or turn any of the unit's front panel button/encoder, do NOT unplug the unit
from the AC wall socket and do NOT turn the mains power switch off. Interruption of the firmware update procedure may result in
corrupted firmware and a malfunctioning unit. In case something went wrong during a firmware update and the unit is
malfunctioning, apply the emergency firmware update procedure described in the next section.

1. Perform the operations described in section 5.1
2. Power the unit off (back panel mains power switch to OFF)
3. Push and keep the standby/mute button pushed and power up the unit (back panel mains power switch to ON). Keep
the standby/mute button pushed for a couple more seconds after you turned the unit on.

Standby mode. Remove the USB stick and turn the unit on. The new firmware is now active. To verify that the
firmware update is effective, navigate to the FACTORY SETTINGS menu and select the FIRMWARE VERSION item. The
