Related quest: Shock Value
Obtained from Scribe Vallincourt, the scrambler automatically turns any Enclave-controlled deathclaws friendly as long as you are within range of the Enclave transmitters. When you are going out of range, the device will first start to beep periodically and finally the deathclaw will die.

Behind the scenes
The Pip-Boy image is identical to the device used to control brainless Spock in the Star Trek: The Original Series episode "Spock's Brain.".

Bugs

 * After Fast Traveling or simply entering into a new location there is a possibility that a Enclave controlled deathclaw will spawn very close to the player. This can happen instantly after you get the device. The deathclaw will always attack anyone whos not a part of your party regardless of their disposition to you. Known Locations where an Enclave controlled deathclaw has spawned/followed after fast traveling or by simply entering a new area: Megaton, the Vault 101 entrance, The Museum of History/Underworld, Canterbury Commons, Citadel, Warrington Station, Point Lookout, The Pitt Downtown, and entering the HQ of Reilly's Rangers.
 * The controller may turn a deathclaw friendly towards you, but it will not become hostile towards nearby Enclave forces. Instead, the deathclaw simply returns to its cage and completely ignores any combat between the player and Enclave forces. The deathclaw does attack creatures, raiders, or Talon Company mercs that approach near it.
 * Mind controlled deathclaws will sometimes not even leave their cage when interacted with.
 * The friendly deathclaw will suddenly die when the Lone Wanderer enters or leaves a location.
