I have a JVC HR VP 693U VCR, and somehow I accidentally activated the ChildLock, and now cannot use the VCR at all. It has locked ME out! I can't find the manual, and it isn't available on the JVC site. This happened once before, and support was able to tell me a couple buttons to push simultaneously to deactivate the ChildLock --- but their support no longer answers questions about these old VCRs. Any help would be appreciated. thank you!
