- To upload more recent firmware to the unit, select the item "**System**" in the left column.
- Click on "**Firmware**" in the upper part of the screen.

## Online download

- If your computer network is connected to the internet, you can check the availability of newer firmware by clicking the button "**Check for new firmware**".
- The touchONE unit verifies whether newer firmware is available on the update server. If there is, it gets downloaded.

## Offline download

- For **touchONE products** you can **download firmware** files into your computer from the [CUE support portal](https://support.cuesystem.com/space/TD/739344444). The downloaded firmware file is the ZIP type and includes firmware for all touchONE units. Unzip the file into a suitable directory on your computer. The firmware files are in the CVCF format.
- For **CUE control system units**, all firmware is part of **Cue Visual Composer**, which you can download [here](https://www.cuesystem.com/EN/Downloads). Open the firmware folder using Cue Visual Composer, menu *File / Firmware Folder…*
- Then press the button "**Choose file**", select the file with firmware for your touchONE unit, and press "**Upload**". In selecting the right CVCF file, check the name and a serial number of your unit in the upper right part of the web page, e.g. touchONE-manager, **CS0537.R01**.009999. The firmware file has to correspond to the name and first two parts of the serial number. For example, to upgrade to firmware version 25.00c select the file **touchONE-manager_CS0537. R01_Firmware_25.00c.cvcf** for the above-mentioned unit.

## Update

- After the file with new firmware is uploaded into the unit, the following screen will come up.
- Apply new firmware by clicking "**Update**".

> 📝 The firmware upgrade takes about one minute and then the unit restarts.

> ⚠️ Do not shut down or disconnect the power (LAN) during the update, as this might damage the unit.

- If the upgrade has been successful, the following screen will come up.
