piCO

Operating Manual
English
Ensure that two AA batteries are correctly
inserted in the battery compartment.
The single button controls all functions:
•
One long button press (>3 seconds) turns
the unit on.
•
A single click scrolls the pointer through
the list of options.
•
A double click selects the required option.
•
One long button press (>3 seconds) turns
the unit off.
Press and hold the button for three
seconds until the display
becomes active. Release the
button. After a 10-second
warm-up period, during which
a start-up screen is displayed,
the main menu will appear.
If a
appears instead of
the main menu, it means
that the instrument has failed to set a fresh
air zero during start-up, perhaps because
the ambient air was not free of carbon
monoxide. Ensure that the instrument is in
fresh air and then double click the button
to repeat the start-up test. If it fails again,
please see Troubleshooting – page 15.
When the pointer is opposite the picture
of an exhaling face, the piCO
+
is ready to
start a breath test. The green LEDs will
flash twice to indicate that the instrument
is ready.
Operation
Attach a breath sampling D-piece and a
new cardboard mouthpiece to the piCO
+
.
Check that all connections are pushed
firmly together.
To start a breath test, the patient should
inhale and hold their breath. Double
click the button to initiate the 15-second
countdown display.
