Breathalyser will not turn on

There are a few reasons it might be behaving that way.

  1.  Weak/Flat batteries.
    - Try replacing with a brand new set of alkaline, non-heavy duty, non-rechargeable batteries.
  2. Calibration
    The unit may be due for calibration - especially if it hasn't been calibrated in the last 6 months.
  3. Chipset problem
    - Contact us at support@andatech.com.au if the device is under a month old OR recently calibrated AND/OR batteries has been recently replaced.
