The SE-R0295 remote was sold with select Toshiba DVD/VHS recorders, including the DVR620. The manual for the recorder will have the instructions for the remote. Crutchfield has the manual for the DVR620 on the product page: https://www.crutchfield.com/S-c7W4uYBFvX6/p_052DVR620/Toshiba-DVR620.html . The current link to the manual is https://pdf.crutchfieldonline.com/ImageBank/v20101107082900/Manuals/052/052DVR620.PDF . See page 12 and subsequent pages for information on using the remote. This does not appear to be a universal remote that can control other devices besides the DVD/VHS recorder. I hope this helps. Cindy Wells
