I was second guessing posting about this, but it is worth a shot. I am working on a KTL CCTV DVR Model 4104N, and I am unable to find beep codes for it. It used to beep twice then it was fine when you powered it on. Now it is one continuous beep, with no pause. I am hoping that I can replace the HDD and it will work fine. I wanted to avoid opening it, until I have some idea of what is wrong. It has one of those stickers that you must break to open it up.
Any insight to my issue would be greatly appreciated, and as a FYI I did look for the companies contact info, as well as looking at online documentation. Thanks in advance.
