If you had the data. We did not, and neither did the vendor, too old. 
That machine had been a problem child from the gitgo, and my crying 
about it finally got CBS to replace the whole system network wide, with 
a much more capable message system.  That box was as buggy as a 10 day 
old road kill, crashing many times a day, and cooking its power supply 
about annually. I was glad to see it hit the bin from my hands after 
installing the new one.

If the window is covered by something opaque to the shorter wavelengths 
of UV light, I saw some propaganda about that old that said they  
estimated its retention at 10,000 years. So it should easily outlast the 
device that uses it.  By about 9.99 eons. :)
