Note: Please remove the battery if the meter is likely to be unused for 
some time. 
Sensor Expiry 
Sensor life ranges from 2 to 5 years and depends upon both the 
amount of exposure to CO and other gases, particularly solvents 
such as alcohol and cleaning fluids. 
When the sensor has expired it will become impossible to obtain a 
correct calibration. When this occurs, the Smoke Check must be 
returned to CareFusion, or an authorised agent, for sensor 
replacement. 
Cleaning 
The mouthpiece adapter may be cleaned using a mild detergent 
solution or replaced if there is risk of contamination. Exposed surfaces 
of the meter, other than the sensor surface, may be wiped with a 
clean, damp cloth. It is recommended that this procedure is 
performed after each use and all used cardboard mouthpieces 
discarded. 
Important note: The sensor surface must not be wiped with any 
aqueous solutions and must not be exposed to solvents e.g. alcohol or 
permanent damage may result.

A full service manual including circuit diagram and parts list is
