The N-395 requires no routine service or calibration other than
changing the battery at least every 24 months.
If service is necessary, contact qualified service personnel or
your local Mallinckrodt representative.
Periodic Safety Checks
It is recommended that the following checks be performed every
24 months.
• Inspect the equipment for mechanical and functional
damage.
• Inspect the safety relevant labels for legibility.
Performance Verification
If the monitor has been visibly damaged or subjected to
mechanical shock (for example, if dropped), qualified service
personnel should perform the procedure in the Performance
Verification section of the service manual.
Cleaning
WARNING: Do not spray, pour, or spill any liquid on the
N-395, its accessories, connectors, switches, or openings in the
chassis.
For surface-cleaning and disinfecting follow your institution’s
procedures or:
§ The N-395 may be surface-cleaned by using a soft cloth
dampened with either a commercial, nonabrasive cleaner or a
solution of 70% alcohol in water, and lightly wiping the
surfaces of the monitor.
§ The N-395 may be disinfected using a soft cloth saturated
with 10% chlorine bleach in tap water solution.
Before attempting to clean an SpO
2 sensor, read the directions for
use enclosed with the sensor. Each sensor model has cleaning
instructions specific to that sensor.
