Operating the Model 7500FO
NOTES:
• Before using the Model 7500FO, please review all contraindications, warnings and cautions.
• Before using the Model 7500FO, the battery must be charged for four (4) hours.
• When the Model 7500FO 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 7500FO 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 7500FO. Contact Nonin Technical Service for assistance.
To verify that the Model 7500FO is functioning properly, it is important to monitor SpO
2
and pulse
rate readings. Use the following procedure to verify that the sensor is working properly.
1. Ensure that the Model 7500FO 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.
CAUTION:
If the device does not beep during the initialization sequence, the
speaker may not be functioning properly. Discontinue use until the situation is
corrected by Nonin Technical Service.
WARNING: This device is intended only as an adjunct device in patient assessment. It
must be used in conjunction with other methods of assessing clinical signs and
symptoms.
WARNING: As with all medical equipment, carefully route patient cables and
connections to reduce the possibility of entanglement, strangulation, or injury to the
patient.
WARNING: Verify all alarm settings and limits during system startup to ensure that
they are set as intended.
