Be cautious of websites that ask you to install "Special Media Players" to view the ITR720 mp4. Standard players like VLC or Windows Media Player can handle almost any MP4. Never install software from an unverified source just to watch a video.
Often, a PDF manual contains QR codes that link directly to the hidden MP4 video files.
Having a local copy of a technical video (MP4 format) is highly beneficial for professionals working in the field.
Ensure "ITR720" is the exact model; sometimes a single digit difference (like ITR700) will yield better results.
