How does Montag keep track of the search for him when he is running from the Hound and the authorities ?

As Montag runs away, he pauses to peer into a house window to see how the search is progressing on the television. He sees the hound running through town and stopping in front of Faber's house for a nervous moment before bounding away. Slightly relieved, Montag continues on as the radio announcer prompts everyone in the area to simultaneously look outside their homes for Montag. Luckily, by the time the given count has expired, Montag has reached the river, where he strips, douses himself in alcohol, and changes into Faber's dirty clothing before floating off down the river, thinking about fire and burning.
