NOTE: If both a Pro 550 Plus and a second, different model handheld (Alpha® models or Astro® 430), are being used at the same time, it is important to pair the collar to the Alpha or Astro handheld first.

The Pro 550 Plus cannot change nor manage collar ID numbers, and cannot change or manage other communication settings.
