I'm inquiring about the electronic furniture locking system you manufacture. I'm particularly interested in obtaining a user manual for this product, preferably in PDF format. If you could provide this document in Portuguese, that would be greatly appreciated. Additionally, I would like to know more about the features and specifications of the locking system. Understanding its installation process and any maintenance guidelines would be beneficial as well. Looking forward to your prompt response so I can proceed with my project efficiently. Thank you!
