NOTES:
• Before using the Model 7500, please review all contraindications, warnings
and cautions.
• Before using the Model 7500, the battery must be charged for four (4) hours.
• When the Model 7500 reaches critical battery, a medium priority alarm will
sound. To clear the alarm: charge the battery and turn the device off and back
on.
Press the ON/STANDBY button. When the unit is first turned on, the
Model 7500 performs a brief initialization sequence.
Verify that all LEDs illuminate and the unit beeps three times during the
first phase of the initialization sequence. If any LED is not lit (except the
AC Power Adapter LED), do not use the Model 7500. Contact NONIN
Customer Support for assistance.
To verify that the Model 7500 is functioning properly, it is important to
monitor SpO

and pulse rate readings. Use the following procedure to
verify that the sensor is working properly.
1. Ensure that the Model 7500 is on, with the sensor connected.
2. Apply the pulse oximeter sensor (see sensor instructions for use).
3. Verify that a good SpO
2
reading is displayed, that a pulse rate value
appears, and that the pulse strength bargraph LED is active.
