Alert 72 (error 72) indicates that you must check for a firmware update before you can continue sharpening. This alert cannot be bypassed—you are now required to verify whether an update is available.

Keeping your firmware up to date helps ensure your Sparx Sharpener performs at its best and has access to the latest features and improvements.

Unlike earlier alerts that could be temporarily dismissed, Alert 72 requires action. You will not be able to sharpen until your sharpener checks for available firmware updates through the Sparx Hockey Mobile App.

Internet Connection Required

An active internet connection (Wi-Fi or cellular data) is required to complete the firmware check. Please ensure your phone is connected to the internet before proceeding.
