The lens heat shield/holder from the dental light has a three prong locking mechanism which locks the lens heat shield/cover into place.The lens heat shield/cover has to be removed by the end user when cleaning the lens or replacing the halogen bulb during routine operator maintenance.The installation instructions, use and care instructions, and labeling clearly state to ensure the lens heat shield/holder is properly secure by snapping the part back into place.Marus initiated a recall on june 10, 2011 to add a tether to the lens heat shield/cover to keep it from falling off the dental light if it is not re-installed properly.The fda closed this recall on 10/26/2012 (please reference fda recall z-2834-2011).Marus notified all distributors of the recall while the recall was open.The doctor and his current service provider could not locate the serial number on this particular light.They both informed marus the light was very old and the serial number tag must have somehow been removed.After following back up with the dentist on 2/8/2017, the dental office informed marus the tether was installed on the dental light and it is working properly.
