It means the present Barometric pressure in the immeadiate area. If your altimeter is not set to the correct barometric pressure, you will get false altitude readings, which could result in disasterous consequences in certain situations.(Possiblity of hitting something on final approach, because you are not as high off the ground as you think you are, as an example )
There is no need to respond to ATC when they give you that information, it is so you can reset your altimeter if necessary.

You can change it manually by putting your mouse cursor over the adjustment knob on the Altimeter(will give you + or - ) then click or use mouse wheel. You can also set the correct setting by pressing B.

29.92 is the standard altimeter setting when you start a flight, it should already be at that default value. Unless you're using real weather. 🙂

Also, that's using the English system, metric will be different.

Yours is set for metric which is 1013 millibars or hPa. US uses 29.92 inches of mercury, same thing different scales. 🙂

No button, global settings will effect all aircraft. The primary altimeter setting on the PFD(main display) should say 29.92 in the lower RH corner.

To check your International settings:
To open the International Settings dialog box
On the main screen, click Settings, and then click International.
-or-
From the Options menu, select Settings, and then click International.
Selecting Units of Measure
Click the arrow on the Units of measure box, and then select the units you want to use.
Click OK
Edit-Had to change some info
