Hi
I've just got my first grand piano delivered yesterday and noticed a couple of things and since I've been playing only digital piano so far I need help to determine what is normal and what isn't.
The piano is 6'2" Kawai GX-3 with dual duplex scaling.

1. I think the damper on the highest note isn't working properly. (see the video)
2. There is ringing for a few seconds after all keys I don't know if it is normal (sympathetic resonance from undamped higher notes and duplex) or I should ask the technician to regulate dampers? (see the video)
3. When the soft pedal is fully pressed the hammers are striking all 3 strings I noticed there is a screw in right keyblock limiting how far keyframe can slide. Since I need to wait 2 weeks for the technician can I fix that myself by turning this screw to fix the soft pedal or should I wait for the technician?

I don't know if this information is helpful but I keep entire house humidity at 40%, the piano is far from windows with no direct sunlight and while it sounds to be tuned (no beating on most of the notes) it sounds flat on all of the notes I didn't ask in the store if it is tuned to concert 440Hz or is an effect of moving and new environment.

It looks like the felt on the highest damper might be cut so it will not damp one string. This is common practice for some manufacturers. They do it to lessen the effect of the transition to the undamped strings.

On the other hand, the fact that another note is causing the same aftertone leads me to believe that some note down in the bass is not damping a harmonic. Take a plectrum and strum the strings of the lower notes and see if you get the same aftertone. That would indicate that a damper is leaking elsewhere.

Kawai usually trims the felt of the last damper to make the transition from damped to undamped notes more gradual.

Regarding item #3, it is common for the soft pedal to shift the action just enough to contact a softer part of the hammer while still striking all 3 strings. The tone quality becomes softer and many professional pianists prefer it this way. But if you want them to strike just 2 strings then yes the screw is what you’d use to adjust that. Be careful not to move it so far that it strikes the adjacent note.

For checking tuning:

Get any free "guitar tuner" app for Android or Apple smartphone.

Play an "A", see what it says.

The top damper wire is rubbing on the side of the guide rail hole bushing felt. It should be centered and not travel left right fore aft when lifting.
This can add some friction and contribute to uneven damper lift/seating.

If you've been playing low-to-mid-price digital pianos, I've noticed something:

. . . They have _way less_ sympathetic resonance (especially "string resonance") than most acoustic pianos.

They sound "dead", compared to most acoustics.

Even on high-end digitals, to reach "acoustic piano" levels of resonance, you have to raise the "string resonance" setting well above its default value -- say, to 8 or 9, out of 10.

I suspect your Kawai -- with "dual duplex scaling" which adds undamped sympathetic strings into the sonic mix -- sounds just about how it's supposed to sound.

All of the above although I would not re adjust the shift(left) pedal but simply not press it as far. Finer pianists use this pedal in increments. Untrained unthinking pianists stomp on it harder to try to get the piano softer !!!

Check the rear duplex. You will find a strip of cloth, usually red, that silences the lower rear duplexes finishing just beyond the bass strings and doubled or tripled back on itself to secure it. Check the 3-4 duplexes beyond that strip. They sometimes ring. If they do, unthread the strip and let it silence the next few strings then fold it back to secure it.
Avoid touching the strings w the bare hands.
