Hi, I understand the "VHPICTURES" code for determining serial numbers on blads, but I have one that confuses me. I have a 500 c/m that has just two letters and the rest numbers. That made it easy for me to figure out. However, I've just purchased a used 500 el/m. The serial number on that starts with UTE and then has 5 numbers. I can't figure out if it's 76 or 69 (UT being 76 and TE being 69). Can anyone figure this out? Thanks in advance!
