The CP-50 had a built-in 1KHZ tone that could be energized by jumpering the two test points on the meter/filter card. Does the CP-55 have this provision? I don't have a manual, and this boat anchor of a computer takes too long to download the manual, plus it is on the credit card machine.
Can anyone answer this question quickly?

As I recall Paul, the tone in the CP-50 was provided in the C.N. 22 NRM card (turned on as you say, by jumping the white and black points on the 109 meter card).I don't think the 222 card has such an oscillator.
Course, I could be wrong.

It should be Dolby tone that is a warble tone around 800hz

Gordon, is that provision available on the Cat 222?

Nope, the Cat. 222 (in any version) does not have a built-in Dolby Tone generator. In fact, it has Dolby-Tone inputs for an external generator. Steve
