M-802 SSB Radio - how do I get my serial #?

[Geoff H.]

I want to double check that my M802 radio is not having a clipping issue and I'm reading that I need to verify what my serial # is ?
Q: How do I get access the Serial #? (I'm sure it's stamped on the back but I'd like to avoid pulling out the electrical panel it's mounted on to get at the back. (Lazy) Is there another way to get this number?

Thanks as always,
Geoff
