icon is displayed so always
watch for it, it will be accompanied by two beeps.

To perform test,
fit a disposable SafeTway mouthpiece (single use only) onto the micro, and give the
following instructions to the subject so that testing is performed properly:
Note that it is advisable to also perform an animated demonstration of the test technique, using a mouthpiece, prior
to the subject performing the test.
a)
Sit upright, fit the noseclip and relax (the use of a nose-clip is recommended),
b)
Hold the unit, keeping it away from your mouth. Do not jerk the unit (this can de-stabilize the unit).
c)
Inhale as deeply as possible, then insert the mouthpiece carefully into your mouth, not like a trumpet, but
clamping it gently between your teeth.
d)
Seal your lips round the mouthpiece and keep your tongue down.
e)
Blow out as fast and as long as possible. Keep blowing for at least 6 seconds. (From the very beginning of the
blow the operator should encourage the subject to keep going in a lively fashion. Keep eye contact with the
subject).
f)
After 6-s instruct the subject to rest –
say ‘Well done!’
