Battery Care
The battery, made of Lithium Ion (Li-Ion) rechargeable cells, is integral to the device and cannot
be replaced by anyone other Nonin Technical Service. The life expectancy of the battery is
approximately 1 year.
For optimal performance, the battery should be replaced once per year to limit the amount of Li
build up if the battery is charged in a cold environment.
Maintenance
Ensuring Optimal Performance
In order to ensure safety and optimal performance of LifeSense, Nonin recommends a yearly
inspection and functional check be performed on the monitor (see Recommended Inspections
and Functional Check section). This inspection and functional check may be performed by Nonin
Technical Services or at your facility. Additionally, the LifeSense monitor should be calibrated
(see Calibration section), and the calibration should be verified using 5% CO
2
gas (a calibration
apparatus, gas valve, and 5% CO
2
verification gas are available from Nonin [see Accessories]).
Please contact Nonin Technical Services if monitor maintenance cannot be performed at your
facility.
Cleaning the Sensor
Refer to individual sensor Instructions for Use for details.
Cleaning the Monitor
Clean the monitor with a soft cloth moistened with isopropyl alcohol. Allow the monitor to dry
completely after cleaning.
Calibration
LifeSense has a built-in zero-point calibration function for CO
2
. Perform the calibration procedure
at least every 6 months, or if the baseline of the CO
2
graph is elevated.
The calibration apparatus (see “Accessories”) is reusable for approximately 100 times. When the
pellets start to turn purple they cannot absorb any more CO
2
and the calibration apparatus must
be replaced. Dispose of the calibration apparatus in accordance with your local, state, or national
regulations concerning waste materials.
CAUTION:
Always turn off the monitor prior to cleaning the monitor or changing the
pulse oximeter sensor or moisture trap and/or filter.
CAUTION:
Do not sterilize or autoclave the monitor or sensors. Do not immerse in
liquids.
