Signal Interference

Signal Interference is a companion perk in the Fallout: New Vegas add-on Dead Money gained while Christine Royce is a companion.

Effects
Due to a beneficial malfunction of Christine's slave collar, she gives a short delay before your collar starts beeping when near a radio or speaker, and then grants you an extra 50% to the duration of time to get out of the signal before it detonates. More specifically, it grants five seconds before the collar starts beeping and five additional seconds before the collar detonates. Increasing the total time one may spend near a radio or speaker from ten to twenty seconds, an effective increase of 100 percent.
