Frequently Asked Questions Stethoscopes Do I need a PC to use the TR-1 or TR-1/EF digital stethoscope? I already have another vendor’s telephonic stethoscope in my system. Do I have to have your product at both ends? What is your warranty? Do I need to purchase any software from you to use the products? How can I get a demo? Scales What are my options if I purchase the cabled version of the scale, the SC-2, then find out later that I really want the wireless version? Does the data port on the SC-2/BT scale still work even though it is wireless? What wireless standard does the SC-2/BT scale use? What is the range of the SC-2/BT wireless scale? If there is a wireless LAN in the house, will there be interference with the SC-2/BT scale? More Links: Contact us for help and product info View our FAQ section Site Map
