Indications for Use
Portable and mobile RF communications equipment can affect medical electrical equipment.
This device is designed to determine the percentage of arterial oxygen saturation of functional hemoglobin.
Factors that may degrade pulse oximeter performance or affect the accuracy of the measurement include the
following:
A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor or sensor.
All parts and accessories connected to the serial port of this device must be certified according to at least IEC
60950 or UL1950 for data-processing equipment.
This device is a precision electronic instrument and must be repaired by trained Nonin personnel only. Field
repair of the device is not possible. Do not attempt to open the case or repair the electronics. Opening the case
may damage the device and void the warranty.
Any sign or evidence of opening the system, field service by non-Nonin personnel, tampering, or any kind of
misuse or abuse of the system, shall void the warranty in its entirety.
