Good news/bad news.
Good news - I believe your model # is WV-D5000 based on your description and web hits.
Bad news - the HD on that camera stands for Heavy Duty, not High Def. If my guess is right, you've got an old, analog, professional camera from the early VHS days. It says "Digital" because it uses digital circuitry instead of vacuum tubes.
Actually, it sounds old enough to pre-date the web, so you're going to have a heck of a time finding an online manual. I did find a paper copy on ebay for $16 if you want to take a peek at that.
