Those are Motorola Quick Call I 2+2 tones. The exact tone frequencies depend on what plan (A, B or Z) the codes were taken from, but Z was the most popular, so we'll go with that here.
CP = 346.7 + 1084.0
CN = 346.7 + 977.2
KN = 716.7 + 977.2
CK = 346.7 + 716.7
It would be helpful if you could tell us what you're listening to with these tones, and why you need the frequencies. If you're trying to decode them using a pager, portable or scanner, don't even bother. QCI decoders went the way of the dinosaurs quite a while ago.
