Garude,
You would change frequencie to 121.5 to transmit your distress call because it is the PROPER ICAO worldwide frequency that you are supposed to transmit on.
If nobody is monitoring it (which there should be!) Then you go over to your nearest flight service station.
It is my understanding from friends down your way that this is the same for you too! maybe remember that!
Yes, like i said... if you dont know something, reference your POH
