Panasonic RF-2200 Back Panel Label - Anyone Seen This One?

[4nradio]

I've owned a few RF-2200s before and have seen pictures of many others on YouTube, Ebay, Google search, etc. However, I've never noticed one with the upper back panel label as shown below on the left. The usual text-only (no warning triangles) is on the right:



The RF-2200 I won at auction recently has the left label above (the radio arrives this Saturday). Has anyone seen this style before? It looks newer to me, so I'm wondering if Panasonic switched to this design in a later production run. Thoughts??

Very likely.
At some recent point in time, there were international standards for various certifications. You might try downloading various manuals for the RF-2200 to see what publication date used those symbols.
