The Collar Diagnostic feature provides a convenient way to use the Halo App to check for any potential issues with your Halo Collar(s). To access diagnostics for your collar, please go to Settings > My Collars, select the collar you wish to inspect, and click on Collar Diagnostic. The Halo Collar will periodically run diagnostic checks on itself. 

Should any issues be detected, and if your collar is still within the one-year warranty period, a warranty replacement request will be automatically initiated, and you will receive an email to confirm your shipping address. If your collar is outside the one-year warranty window or if you have any questions regarding the warranty process, we encourage you to reach out to our live support team through the article: How to Contact Customer Support. 

Additionally, please note that even if your warranty has expired, we are committed to extending your warranty in the event of a diagnostic error. For more information regarding your warranty, please see our Warranty Policy Details. Thank you for being a valued Pack Member!
