Sorry. Mike. No suggestions. My 5630 requires two buttons on the remote to activate the test tones. But I *assume* if yours is similar that you already know that.
Coincidentally (and completely off topic), it isn't "pink" noise. At least on the 5630. It's some narrow band of noise centered @ 1K Hz. Unless the definition of "pink noise" has changed. Time to check the glossary again...
