Device Operation
Step 1:
Insert the appropriate number of coins into
the coin slot.
Voice prompt:
“Thank you. Please take
a straw from the tray and wait until the
machine counts down to ‘0’ in the
display.”
Step 2:
Take a straw from the tray and insert it into the
mouthpiece slot (”bullseye”). When the device indicates
“Blow”, blow into the mouthpiece steadily until the device
indicates that sampling is completed. If a successful
sample is not taken, the device will prompt you to wait,
then blow another breath sample until sampling is
successful.
Voice prompt:
“Insert the straw securely into
the ‘bullseye’ until the tone ends. Three,
two, one <
CHIME SOUND
>. Sampling is
completed.”
Voice prompt (if successful sample is not taken,
usually due to weak breath):
“The device
does not sense a proper breath sample.
Please wait and try again.”
