BF2, Headset Problem

I purchased Logitech USB 350 Headset for use with BF2.

I plugged in the headset to PC, it recognizes headset. I use the MS self test to test the headset, I can hear my self speak into mic, so sound is good.

I play BF2 with it and have no idea how to team speak w/it? I can hear all sounds thru headset, and other people speaking. I understand letter "V" is to speak during the game but I can not hear myslef on the game nor can anyone esle here me when pressing "V". I check the audio options and think they are ok.

Can someone explain/teach me how to use.

Thanks.
