4.1 Abort Messages
If your test does not satisfy the test requirements, the
interlock will show one of the following messages to let you
know how to proceed.
Abort Early
The blow/hum sample was not long enough, blow softly and
steadily until the beep changes to a higher tone.
Abort Hum
Blow/hum not performed properly, Try varying the pitch of
your hum - if it’s too low or too high, it may not be detected.
Abort Hard
Caused by blowing too hard into the interlock, blow softer.
Don’t Inhale
Not enough pressure was detected, or breath was inhaled at
the start of the test. Hold the interlock well away from your
mouth when you inhale and bring it to your mouth when
you’re ready to start blowing.
Abort Tamper
Something is blocking the flow of air through the interlock.
Make sure that your hand isn't covering the vent on the back.
Check for obstacles, remove them and blow again.
