Troubleshooting
The unit fails to turn on
If the unit fails to turn on, replace the batteries.
Ensure that the batteries are inserted the correct
way around, matching the symbols moulded into
the plastic.
High readings recorded for reported non-smoker
If a breath test on a non-smoker gives an indication of CO being present, it may indicate the following:
1.
A high ambient level of CO (possibly due to a faulty combustion appliance or exhaust fumes).
2.
The effects of passive smoking.
3.
The device is contaminated by alcohol or another organic substance.
4.
The patient may have a very high level of hydrogen on their breath, which can be generated in the
human digestive system.
5.
The sensor may have drifted out of specification (see below).
