3M TR-300 protect medical staff

Works allowing the use of stethoscopes with out the weight of battery on you head I use 3m back pack and or use waist belt for power unit. Everything has auto easy use and warning sounds for nearing low battery and filter advanced so you can plan a filter change Cleaning TR-300 for CoVid is en easy 123 Process. Directions are on 3M site just enter how to clean TR-300 what video. There are direction included with the unit documents as well. Medical centers, hospital have cleaning for those providers as well.
