If your 1st generation NObreath is displaying the word, NObreath, followed by 'v' and some numbers, this means that there is a new firmware update available. It is advised to keep your NObreath device up to date with the latest firmware to avoid any complications. Please contact [your local distributor](https://www.bedfont.com/find-my-distributor/) to arrange an update.

If the problem persists or has not been resolved by the information provided above, please contact your local distributor for more advice. Find out who your local distributor is from our website [here](https://www.bedfont.com/find-my-distributor).
