Investigation: Radio Interference | Walkthrough The Bureau Guide

Radio message sounds like a mantra.

First Investigation is rather simple: when you wake up, talk to DaSilva about radio standing at the end of the desk. Approach the device and launch it. You'll hear a weird announcement, containing numbers and name of the month. Carter will write this down on the piece of the paper next to the radio.

Correct combination is : 250, north, 892.

Go to the communication opposite to your room. Talk with officer Chulsky and talk her about a weird signal in radio. Then give her correct coordinates, which are: 250, north, 892. Congratulations, you have saved few humans against aliens!
