Troubleshooting and Maintenance

• Do not use the NPB-290; contact qualified service

personnel or your local Mallinckrodt representative.

3. The monitor does not sound a tone indicating successful

completion of POST.

• The monitor has failed the power-on self-test. Do not use

the monitor. This tone not only indicates the successful

completion of POST, but it confirms that the audible

alarm is functional. Contact qualified service personnel

or your local Mallinckrodt representative.

4. The Pulse Search indicator is lit for more than 10 seconds

while the sensor is connected to the patient.

• Check the sensor directions for use to determine if an

appropriate sensor is being used and if it is applied

properly. Check sensor and extension cable connections.

Test the sensor on someone else. Try another sensor or

extension cable.

• Perfusion may be too low for the NPB-290 to track the

pulse. Check the patient. Test the instrument on

someone else. Change the sensor site. Try another type

of sensor.

• Excessive patient motion may be preventing the

NPB-290 from tracking the pulse. Keep the patient still,

if possible. Verify that the sensor is securely applied, and

replace it if necessary. Change the sensor site. Use a

type of sensor that tolerates more patient movement (for

example, an adhesive sensor).

• The sensor may be too tight, there may be excessive

ambient light, or the sensor may be on an extremity with

a blood pressure cuff, arterial catheter, or intravascular

line. Reposition sensor, as necessary.

• Excessive environmental motion or electromagnetic

interference may be preventing the NPB-290 from

tracking the pulse. Remove the source of interference or

try to stabilize the environment, or do both.
