Patient MRI Checklist

When your doctor requests an MRI scan:

• Tell your physician you have an implanted spinal cord stimulator device.
• Find your patient ID card. If lost, contact your Nevro Care Team for a replacement.

When making your MRI appointment:

• Provide the MRI facility with the following information:
  • You have a Nevro HFX spinal cord stimulator.
  • Details of any other medical device implants.
  • A detailed description of your device (product number, leads, components) from your patient ID card.
  • Contact information of the implanting physician.
  • The Nevro HFX MRI Guidelines (available at Nevro.com/manuals).

Preparing for your MRI appointment:

• Contact your Nevro Care Team to confirm the safety of the ordered MRI scan.
• Your Nevro Care Team will assist you in placing your device in MRI Mode using your HFX App prior to the scan. Refer to pages 10-11 or NevroHFX.com/resources/en-au/hfx-app for instructions.

At your MRI appointment:

• Bring your patient ID card and HFX App.
• Your MRI Tech will confirm if your device is in MRI Mode before the scan.

After your MRI appointment:

• Click "Exit MRI Mode" and follow the prompts to exit MRI Mode and turn stimulation back ON (page 11).
• If using Manual Mode, contact your Nevro Care Team to ensure your device is programmed to your pre-MRI settings.

Note: HFX and HFX iQ are approved for MRI scans under specific conditions. Different device models and lead types have different approved scanning conditions. Review the Nevro HFX MRI Guidelines carefully with your Nevro HFX Care Team before any MRI scan.

Ensure your device is fully charged before your MRI scan.

Get familiar with your charger

2. Power Adapter Port (?)
3. Charger Battery Level Indicator (?)
4. Charge Start Button (▶️)
5. Antenna Strength Indicator (?)
6. Device Battery Level Indicator (?)

[Illustration of the charger with numbered callouts]

Charging tips

1. Charging times vary based on usage frequency and settings.
2. If the Charging Coil has an insufficient connection (indicated by Antenna Strength Indicator lights), slowly reposition the Charging Coil and wait 3 seconds for the indicator to update. Repeat as needed.
3. If charging time is shorter than expected, ensure your device is turned ON via the HFX App. The Stim ON Button (1) on the Home screen will be illuminated.

Charging reminders

• You can receive stimulation while charging.
• Do not charge the implant while the charger is plugged into the wall. Always remove the power adapter before pressing the Charge Start Button.
• After charging, plug the charger back into the power adapter and then into the wall to prepare for the next session.
• Recharge your device regularly to establish a routine.
• The device site may become warm during charging. If you experience pain or discomfort, stop charging and contact your Nevro Care Team at +61 488845285.
• If charging times increase significantly, contact your Nevro Care Team at +61 488845285.

How to prepare for charging

Place the center of the circular Charging Coil over the top of your device. The top of your device should be centered on the Charging Coil.

[Illustration showing the correct placement of the charging coil over the implanted device]

How to start charging

1. Press the Charge Start Button. The Charger Battery Level Indicator light will illuminate. The charger will beep and search for your device. The beeping continues until a connection is made.
2. If no connection is made within 10 seconds, you will hear one long beep, and the charger will shut OFF. Reposition the Charging Coil and press the Charge Start Button again.
3. A connection is made when the outer ring of the Antenna Strength Indicator appears. More rings indicate a better connection. If only the middle dot is illuminated, the connection is poor, and charging will not occur.
4. When the charger is correctly positioned, the Battery Level Indicator will light up.

If the connection is insufficient or lost, reposition the blue Charging Coil slowly and repeat the charging steps. Charging is in progress when the Battery Level Indicator and Antenna Strength Indicator circles are lit. The number of lit dots on the Battery Level Indicator increases as charging progresses. If the connection is lost, your charger will beep. Reposition the Charging Coil and repeat the steps. If only the inner dot is illuminated on the Antenna Strength Indicator, you are not connected.

[Illustration showing different coupling strengths on the Antenna Strength Indicator]

[Illustration of the charger's control panel with numbered indicators]

What to do when you're done charging

1. When charging is complete, you will hear one long beep, and the charger will automatically turn OFF. Check the device battery level on your HFX App to ensure it is fully charged (four dots).
2. Use your HFX App to confirm your device is turned ON.
3. Plug your charger into the wall socket to ensure it is ready for the next charging session. Connect the power adapter to the charger's Power Adaptor Port, then plug the adapter into the wall socket. The orange light indicates the charger is recharging; this is complete when the orange light turns OFF.

How to Use Your Charging Belt (CHGR2500)

Use the charging belt to secure the Charging Coil's position on your body for consistent charging.

How to use the charging belt

1. Place the blue Charging Coil in the pouch on your charger belt and securely attach the belt around your waist. Use the hook and loop fasteners to secure the Charging Coil cable.
2. Start charging and move the Charging Coil until it connects with your device.
3. If you need to move during charging, insert your charger into the holster and clip the holster to your belt or pants.

[Illustration showing the charging belt with the charger and coil attached]

Charging belt tips

• Locate the implant site of your battery.
• Place the blue paddle on top of the battery, ensuring a thin layer between the paddle and your skin. The ideal placement is directly on the rounded edge of the battery.
• Turn your charger on using the power button on the front blue panel.
• Your charger will emit a chirping sound as it attempts to locate your battery.
• Once a connection is made, 1-2 rings will be lit on the target icon, and charging will commence. A long beep indicates charging is complete.
