Hello. I need to know how to get an operators manual for your model HEM-609 N digital wrist blood pressure monitor. I registered as the web-site asked and selected the model number. Then a pop-up asked me to upload the manual or to enter my url. I clicked on upload and nothing happened. I do not know what a url is or what mine might be. Can someone please help me to obtain the manual? Thank you. Raymond Victor gort1950@optonline.net
