I just recently had to deal with all of the nonsense that we're discussing in this thread - proving it has an LSA, without giving out the SN.
This was the best solution I could come up with at the time (which happens to have been 01:24:39 am ...)
-- In the 243-ZONES menu, activate the "Show Clock" option (offhand, button #3 - I think)
-- Take a digital photo of:
MENU -> SETUP -> SYSTEM INFORMATION -> UNIT INFO
This will show the status of the Activation, the S/N and the Key #, along with the current date/time (My idea of providng some sort of "security blanket" for the buyer, that you didn't shoot the photo ages ago, and have since transferred the LSA to another unit.)
To protect the SN & Key, but sill provide him with enough of digits to assure that the unit was indeed an RTV -5504, and that when he recieves the shipment, that what's in box was the unit that took the photo of: multiple thick stacks of post-it notes were strategically applied to the TV screen, leaving the fist 8 digits (7 of which are the model number of the unit) and the last 2 digits, prior to taking the photo.
The photo is attached -
I got paid, he got a 5504 w/ an LSA - everyone is happy-happy-happy (just like if were garlic cloves in Emeril's kitchen...)
