As instructed, press the large button [
FSB
] to
Select
the displayed
option, or the small button [
FSA
] to go to the
Next
.
The first option enables you to start a new subject test: if you select
NEW TEST
then you cannot switch the instrument off until either a
breath sample has been taken and analysed, or you have logged a
‘fail to provide’
. The second option recalls [and prints] the result of the
last breath test. The third option switches the
500
off. If the
instrument is not used for a pre-set time (usually 5 minutes), it
switches off automatically.
STEP 4 -
Attach a New Mouthpiece
If you chose to breath test a new subject,
[
NEW TEST]
this proceeds as follows.
The mouthpiece must be attached in a hygienic manner, or the
subject could justifiably object to putting it in their mouth. Tear open
the wrapper from the non-lipped end, and peel back far enough to
expose the hole in the side. Now, holding the mouthpiece through
the wrapper around the blowing [lipped] end, push the side hole over
the
500’s
sampling port, so it locks firmly into place. You may attach
it either way round, whichever is more convenient. Now remove the
wrapper completely [or have the subject do this themself].
