[Elecraft] K2 question/new owner

[bukar]

I hope that I am posting this properly, if not please correct me. :-)

I am the new owner of K2/10 #5001. I am more used to tuning up the hybrid Kenwoods so while I am looking forward to moving to this more modern radio I have some questions.

I think that I must have toggled something off as I no longer can get a tone when I push the "tune" switch on and off. It was working but I was in the menus and fear I have done something to cause this.  I can't find the page in the manual to correct this. Any suggestions?

Also, when I tune the radio with my LDG z100 tuner  should I dial back the power on the rig to 3-2 watts before tuning, get a match and then go back to 10 watts?

I don't understand the read out I get on the display.  The Po number that is displayed after the tune up, is that the recommended max power to use at that particular match? I am trying to keep my power out to 10 watts but some matches even a few kelos apart will display a Po reading from 15 to >5 as I tune across the band.

I am using the rig SSB into a 80 meter dilpole at 40 feet.
