Lost password for DELL M109S mini projector

Hi everybody, I am a new member, I tried to search in the forum but had no lck at all.
Hope that you can help me.
I have an old M109S mini projector, after long time I wanted to use it, but I forgot the password.
I have asked Dell client support and they said there is no way to reset the password.
I really doubt that this is true, does anybody know if there is any way to fix the problem or the only solution is to throw away this projector?
Thanks in advance for your cooperation.
Stefano
