Jungson DVD player defaults - Help

I need some help with my DVD player. Let me start by saying I am a complete nitwit when it comes to the technicalities of audio gear and/or over 50, which seems to amount to the same thing! With that disclaimer, here's the creek I'm up: Upon turning on my Jungson New Moon 2 DVD player, and selecting "play" a screen informed me that the "child lock" setting was "on" and I could not proceed without entering a "code". [Player was purchased used, with no manual. Has worked fine, without such a warning, for months.] Lacking the "code" required, I tried every way I could find to bypass it. Eventually, I found hidden in the "menu" an option that said, "no code". I selected that option, and was promptly asked for the "code" - presumably a code is needed to opt not use a code! In any case, having hit a dead end, I attempted another workaround. The menu offered me an option of "no defaults" or something to that effect (I can't remember wording precisely). Thinking the "code" might be a "default" and that a menu showing what defaults I might choose to discard might appear, I selected "no defaults". My tv monitor then showed black & white with the scrambled dvd menu spinning through, as if, hmmmm, there was no longer any "defaults" determining an appropriate signal. Which brings me to my two questions: 1. How can I restore "defaults" to a Jungson New Moon 2 DVD player? 2. If I am able to restore the defaults, how can I make it so a "parental code" is not required? Thanks very much for any help!
If you unplug it it may erase and restore to default tho it may take time for an internal battery to drain, there are many players that when holding a cetain button in for a few seconds you can restore default, further try code #1234....or #oooo as most folks dont actually change a simple factory code, good luck.
