Here you can download instructions for use and product labelling for the HF3 device. All downloads are in PDF format, which should open automatically on most modern platforms such as Apple, Android, Chrome and Linux. If you use Windows, you may need to install a PDF reader such as Adobe Acrobat Reader if one is not already installed on your computer.

If you require a printed copy of the Instructions for Use, please email [email protected] and include your device serial number found on the back of the HF3 controller.
