Numbers transmission

I was just re-watching the episode Namaste and in the beginning when Ajira 316 goes back to the isalnd, when they are attempting to land you can hear the transmission of 4,8,15,16... Now i thought that since they turned off the loop recording and the Looking glass station that transmissions could be sent now without any interruptions. So why is the loop still transmitting when they land is supposed 2007? can anyone answer this?
