Why does a dash appear in the %SpO 2 display of my Nonin 7500 Medical Equipment?
A dash appearing in the %SpO2 display indicates that the Nonin Medical Equipment is detecting an inadequate signal from the finger, or the finger was removed from the sensor. Try repositioning or reinserting the finger, keeping the sensor motionless for at least 10 seconds. It may also indicate that the Model 7500 is not functioning correctly. Turn the unit off, check all connections, and retry.
What to do if I can't obtain a green pulse display on the bargraph of my Nonin 7500?
If you're unable to obtain a green pulse display on the bargraph, it could be due to several reasons. The patient's pulse strength may be indiscernible or poorly perfused; reposition the finger, insert a different finger, and keep the sensor motionless for at least 10 seconds. Reduced circulation due to excess pressure on the sensor can also cause this; allow the hand to rest comfortably. Other potential causes include a cold finger (warm the finger), incorrect sensor application (apply correctly), interference from medical equipment (reduce or eliminate interference), the red LED not being lit (ensure the sensor is securely attached), or excessive patient motion (reduce patient motion).
What to do if my Nonin Medical Equipment Model 7500 will not activate?
If your Nonin Medical Equipment Model 7500 will not activate, it is likely due to the unit having no power. Plug in the AC adapter.
Why is my Nonin 7500 Medical Equipment in Alarm mode, but I can't hear any audible alarms?
If your Nonin Medical Equipment is in Alarm mode but no audible alarms can be heard, it may be because the 2-minute Alarm Silence button is activated.

Another possibility is that the audible volume is set to “oFF” in the alarm limits; adjust the volume through the setup mode.
Why is there frequent or steady pulse quality indication on my Nonin Medical Equipment?
Frequent or steady pulse quality indication on your Nonin Medical Equipment can occur due to excessive ambient light; shield the sensor from the light source. It may also happen if the Model 7500 is applied to a polished or artificial fingernail; apply the sensor to a finger without artificial or polished nails. Other possible causes include the red LED not being lit (ensure the sensor is securely attached to the Model 7500) or excessive patient motion (reduce patient motion).
Why will my Nonin Medical Equipment Model 7500 not operate on batteries?
If your Nonin Medical Equipment Model 7500 will not operate on batteries, it could be because the battery pack is not charged. Plug in the Model 7500 AC Adapter to charge the battery pack. If that doesn't work, the battery pack may be inoperable; contact NONIN Customer Support for repair or replacement.
Why does my Nonin Medical Equipment Model 7500 not record data?

What to do if a dash (-) appears in the %SpO display on my Nonin 7500 Medical Equipment?
If a dash appears in the %SpO display of your Nonin Medical Equipment, it indicates an inadequate signal from the finger.

How to fix no green pulse display on Nonin 7500 Medical Equipment?
If you're not getting a green pulse display on the bargraph of your Nonin Medical Equipment, it could be due to several reasons. The patient's pulse strength might be weak, or circulation is reduced because of excess pressure on the sensor. Try repositioning the finger or using a different finger, keeping it still for at least 10 seconds. Ensure the hand rests comfortably without pressing the sensor against a hard surface. If the finger is cold, warm it by rubbing or covering it. Also, make sure that the sensor is applied correctly and is securely attached to the Model 7500. Reduce or eliminate any interference from sources like arterial catheters or blood pressure cuffs. Check the sensor for any visible signs of deterioration.
