and the alarm will sound momentarily after the unit is first switched
on. When the battery has completely expired the above will be
displayed continuously and the battery must be replaced.
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.
