FAQ toggle button

To check the status of your device, go to the Home screen on your HFX App. You will see the “Stim ON/OFF” Button in the upper right-hand corner. You will know your device is ON when you see “Stim ON” next to the green icon.

What should I do about my pain medication?
FAQ toggle button

It’s possible you’ll be able to stop or decrease your pain medication; however, your doctor will provide guidance on adjustments to your pain medication.

How often will I need to charge?
FAQ toggle button

Charging will usually take 30 minutes daily but can vary depending on your settings. Most people choose to charge based on a routine that fits their lifestyle, like when they’re watching TV.

The battery level indicator on your HFX App will send you a notification when your battery level is low and needs recharging. You can also see your current battery level at the bottom of your Home screen.

How long will my battery last?
FAQ toggle button

HFX is designed to last at least 10 years.

Can I drive or sleep with HFX on?
FAQ toggle button

Yes, HFX offers programs that can be used while driving or sleeping.

Can I fly with HFX? What happens when I go through airport security?
FAQ toggle button

Yes, you can fly if you first confirm your doctor is OK with it. Remember to keep your charger in your carry-on luggage in case you need it.

Like people with a pacemaker, when you go through security, you’ll let them know you have an implanted device, and they will direct you to the appropriate place. You may be escorted around the security machine or occasionally, they may need you to go through the security machine. If this happens, turn your stimulation OFF using your HFX App and go through the security machine. Once on the other side, use your HFX App to turn your device ON for your flight.

Do international data charges apply to my HFX App if I travel?
FAQ toggle button

Yes, there will be international charges based on your existing data plan.
