I have a VR-509 Reciever by Kenwood. My remote keeps flashing the low battery message. It used to light up so I could see it in the dark, but it doesn't do this anymore. I bought some new batteries last night, put them in, and nothing has changed. The low battery icon flashes and the remote is not lit up. Anyone know why this is happening? Is there some button I have to press on the remote to tell it the batteries have changed? The batteries are Duracells. I got them from Best Buy, they are not dead. The expiration on them is sometime around 2008. I bought the reciever from Etronics online. I need help, please!!!
