Lost my Tower, how to get them back?

[pegruder 65]

So I'm currently mid flight and had to step away for a few minutes.  When I returned ATC is no longer speaking to me.  I figure I must have gone out of range of the previous ATC.  Is there a way to find out what frequency you should tune to is and/or a way to restart contact mid-flight?

 

Edit:  Found the frequency finder but every frequency I find tells me to tune to 118.00.  When I do there I'm getting a repetitive "Check Frequency" message.

In  the Config panel, check the option on the main P2A Setup tab to "Show ATC Assignments".  Then the currently assigned frequency will show up in small while letters beneath the Com area on the main screen.

Aha!  Thanks Dave!
