Notice: OEM remote controls are replacement parts that do not require programming for the original application and are as supplied by the manufacturer with no batteries or instructions. Operating instructions for the remote control will be in the original equipment owners manual or for subs the manual for models listed as OEM in this ad. If needed owners manuals can often be downloaded from the manufacturers website. For OE subs the remote will usually operate in a similar manner as the original. If you need a manual for a sub part that has programming for other devices or just to better describe the sub remote look for a manual for the models listed as OEM for the part number of the purchased remote. Customers having trouble locating a manual may send the model number of the equipment and the remote part number and I will look for one online and in my personal manual library to try to locate a copy. I am also a long time service tech and can answer most technical questions relating to these parts for customers that have a specific question. Always include the equipment model number and the remote part number for any inquiries.
