Panasonic RC-6551 and RC-707

[CanClock]

Hi I was wondering what are the different variations within these model numbers? Are there any manuals available for them?

For example I just purchased a RC-6551C (Black model) and was wondering what does the "C" at the end indicate? Thanks!

There is a service manuals for the Panasonic, but I don't have access to it. The letters at the end of clocks typically just signify a later model, likely with some simple internal change.

Different variations I've seen on the internet:

North American models (RC-6551)
White case with silver face
Black case with silver face

Japanese models (RC-707)
White case with green-silver face
Black case with green-silver face
Black case with silver-black face (UV light)

I have found a Service Manual online for the Panasonic RC-707B. It appears to be a European version. You can view/download it here: https://archive.org/details/manual_R...IC_EN/mode/2up
