Dave,
Per X-Blue Courtney, there is a three year warranty on all equipment (KSU & Sets) from the date of installation
except wireless sets ! . This is one year.
At the time of installation you will need to notate the model and serial numbers of all equipment installed and have a copy of this information with the installation date to accompany the equipment when an RMA is issued for warranty repair.
Now this allows you to stock equipment without worrying about the warranty clock ticking while it is on your shelf.
