5.2.2 Updating the firmware (Firmware Update procedure)
Once the USB stick is ready with the appropriate files, the effective firmware update can be engaged. To do so, follow the steps of
the Software Update procedure:
1. Connect the USB stick to the A-shaped USB port of the CONTROL board at the rear of your C1 unit.
2. Turn the unit on if it is in standby or powered-off. Navigate to the C1_SETUP>>FACTORY_SETTING menu and select the
UPDATE_FIRMWARE item.
3. Start the Firmware Update process by applying a Normal Push [NP].
4. Once the Firmware Update is done, the unit automatically goes into Standby. Please note that the unit will perform a
quick Reset (display turning off and back on) during this procedure. Remove the USB stick and wake the unit from
Standby. The new firmware should now be active.
5. To verify that the Firmware Update was effective, navigate to the C1_SETUP>>FACTORY_SETTING menu and select the
FIRMWARE_VERSION item. Check that the displayed firmware version number matches the version number of the
firmware update image.
Note: The Firmware Update process can last several minutes (about 10 minutes), do NOT interrupt it!
When performing a Firmware Update, do NOT interact with the unit or the remote control, do NOT unplug the unit from the AC wall
outlet and do NOT turn the mains power switch off. Interruption of the Firmware Update procedure may result in corrupted
firmware and non functioning unit. In case something has gone wrong during a Firmware Update and the unit is not functioning
correctly anymore, apply the Emergency Firmware Update procedure described in the next section.
5.2.3 Emergency Firmware Update procedure
Apply the following Emergency Firmware Update procedure if your unit is not functioning correctly after a failed Firmware Update
procedure:
1. Turn the unit completely off by setting the Power on/off switch to off.
2. Prepare and insert the USB key with the appropriate firmware image for your unit (make sure all files are present).
3. Push the Control Knob and power-up the unit by setting the Power on/off switch to on. Keep the Control Knob pushed
until you hear the internal relay click (a couple of seconds).
4. The unit will start up in Emergency Firmware Update mode and will update its internal firmware with the firmware
images present on the USB stick. Do not interrupt or unplug the unit until the Emergency Firmware Update is finished.
This may take several minutes. Please note that the unit will perform a quick Reset (display turning off and back on)
during this procedure.
5. Once the Emergency Firmware Update is finished, the units goes into Standby mode. Remove the USB stick and wake-
up the unit by a Normal Push [NP]. The unit should now start-up properly with the new Firmware.
