After examining the readings, the unit can either be
switched off using the ON/OFF Power key
or another
measurement can be carried out by pressing the Select
Function
key for at least three seconds.
To save the battery, the unit will switch OFF
automatically after three minutes if not used.
Warning/Cautions
If higher than expected levels of CO are displayed
this could be due to CO poisoning and medical
attention should be immediately sort.
The CO Check+ has a cross-sensitivity to hydrogen
(from some gastro-intestinal disorders) which may
affect the reading.
Cleaning with products that contain alcohol may
result in permanent damage to the sensor. (See
page 13 for non-alcohol wipes)
The battery should be changed when the word
‘BAT’ appears on the display.
The disposable cardboard mouthpieces are single-use
only. Re-use of these single use mouthpieces can
increase the risk of cross infection and the mouthpiece
should be disposed of after use by the patient.
