Why does my screen say NObreath followed by numbers?

Why is my screen stuck saying NObreath with numbers?

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 or Bedfont to arrange an update.

If the problem persists or has not been resolved by the information provided above, please contact Bedfont or your local distributor for more advice.
