What is the meaning of "ka-chong"?

[mokbon]

Hi~

Marshall: I mean, you know, guys see the ring, it's like ka-chong, Marshall parking only.

is this based on sound, an onomatopoeia?

I've no idea what your sentence means, but ker-ching, with emphasis on ching, imitates onomatopoeically the sound of an old-fashioned cash register.
