Frequently Asked Questions

What is included in the 7500 package assembly?

  • Model 7500 Tabletop Pulse Oximeter
  • One (1) 8000AA 3-meter finger clip sensor
  • 7.2 V battery pack
  • Operator’s Manual
  • AC adapter

What is the longest overall combination of sensor and extension cable that can be used with the 7500?

The recommended overall maximum length of the sensor and extension cable is 40 feet (12 meters).

How many hours of pulse oximetry data can be stored in memory for download?

Up to 70 hours of pulse rate and SpO2 data may be stored. nVision software may be used to retrieve and analyze the data.

How is the memory cleared?

Patient memory can be cleared using the Model 7500’s Setup mode. Press the Limits button to enter Setup mode, and use the Limits button again to scroll through the device’s options until Memory Clear is displayed. Select “Yes” or “No” using the Plus (+) or Minus (-) buttons to clear patient memory, and then confirm your selection using the Limits button.

What kind of batteries can I use in the Model 7500?

Nonin’s rechargeable NiMH battery pack is required for battery operation of the 7500.

Can the Model 7500 be used without a battery pack in place?

Yes. The Model 7500 can be operated on AC power without a battery pack.

How many hours of battery life can I expect?

Sixteen (16) hours minimum when fully charged.

How long does it take to recharge the battery pack?

Approximately four hours if the battery pack is completely discharged and the system is not in use. The battery pack continuously charges while the device is plugged into AC power. Charging will be longer if the system is in use.

What is the Patient Security Mode and how does it work?

Alarm limits cannot be changed when the Model 7500 is in Patient Security Mode. Security mode prevents accidental changes to critical parameters. The Model 7500 allows users to lock and unlock alarm limits, volume settings, and time settings through the use of Patient Security Mode. Patient Security Mode remains active even when the device is turned off and then turns back on. Patient Security Mode is retained even when both external and battery power are lost. When the Patient Security Mode is enabled, operators cannot change SpO2 or Pulse Rate limits or Alarm Volume – though it is still possible to view those settings. In Patient Security Mode, operators cannot view or set the time and date. To enter Patient Security Mode, press and hold the Alarm Silence button while turning off the device. To exit Patient Security Mode, press and hold the Alarm Silence and Limits buttons while turning on the device.

To view whether Patient Security Mode is active, the Model 7500 must be restarted. When the device is restarted, the Patient Security Mode status is displayed on the Numeric LEDs for one second.

“SEC on” is displayed when Patient Security Mode is enabled.

“SEC off” is displayed when Patient Security Mode is disabled.

Can the Model 7500 be used in Homecare setting?

Yes, the Model 7500 may be used for Homecare. The Patient Security Mode makes the device ideal for this application.

Can the Model 7500 be used for EMS application?

Yes, the Model 7500 may be used for EMS.

Can the Model 7500 be used with neonates?

Yes, the Model 7500 may be used to monitor neonatal patients when used with an appropriate neonatal sensor.

Does the oximeter require calibration?

No calibration is required.

What is the warranty period for the Model 7500?

Battery Pack – 1 Year

Oximetry Module – 3 Years

What is the repair fee on an out-of-warranty monitor?

The out-of-warranty repair fee is $225.
