Maintenance
The monitor requires no routine service other than any performance testing mandated by the operator’s
institution. The
Troubleshooting section on page 116 discusses potential difficulties, their possible causes, and
suggestions for resolving them.
Periodic maintenance is recommended according to operating hours:
•
The CO
2
Pump should be replaced every 30,000 operating hours.
•
A calibration should be performed after the initial 1,200 hours of use, and following that calibration
once a year or every 4,000 operating hours, whichever comes first (see
CO2 Calibration on page 112 ).
•
The monitor’s number of hours remaining until the 30,000 hour operating limit before service is
required is displayed each time when the unit is powered on. This can also be viewed in the Service
Screen.
•
Battery back-up time of the Li-ion battery may degrade over a period of time. To avoid degradation of
battery capacity, it is recommended that the battery pack be replaced every two years.
Note: Contact your local representative to order spare parts, calibration kits, or to get answers to any
questions regarding service and periodic maintenance.
Replacing the Fuses
The monitor is protected from electrical surges by two fuses. If the fuses blow, the monitor will not turn on and
the battery pack will not charge.
To replace the fuses, turn the monitor off and disconnect the power cord from the monitor.
The fuses are located in the back of the monitor below the electrical cord connection. Use a flat screwdriver to
pry out the fuse housing cover, and replace the fuses with fuses of the same rating only (F3.15A 250 Volt). Push
the fuse housing cover closed, then reconnect the power cord and turn the monitor on.
Note: Blown fuses indicate that an abnormal electrical condition occurred. If the cause is not known, contact
your representative to determine if servicing is required.
