If the breathalyser start up or countdown sequence time is taking longer than usual, it could be because:

Possible Cause #1

Battery power is low

Solution
Replace with a new set of batteries. Read more on What batteries can I use with my breathalyser?

Possible Cause #2
Unit requires calibration
Solution
