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.

Trivia

 * The Pipboy image is identical to the device used to control brainless Spock in the Star Trek: the original series episode "Spock's Brain"

Bugs

 * On at least one occasion, after fast traveling to Megaton immediately after receiving the Scrambler, a friendly Deathclaw had appeared, and started attacking the town.
 * There was one occasion after receiving the device and fast-traveling to Chaste Acres Dairy Farm, a regular Deathclaw will appear to follow the player, but it is marked as hostile. After all the enemies (and Brahmin) in the area are dead, the Deathclaw will turn against the player. It is not known if this is a bug or not.
 * The Deathclaw may attack Brotherhood of Steel Outcasts if they are encountered, although they will not be marked as hostile or attack you.
 * 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.
 * On at least one occasion (on Hard) Fast-Travelling to Deathclaw Sanctuary, where there is an Enclave-controlled Deathclaw waiting for you, the Deathclaw immediately falls dead, as if you had the Deathclaw in your control and then you went out of range.
 * On at least one occasion (on Very Hard) a Deathclaw will suddenly be following you post-fast-travel and will be perfectly friendly to everyone in Tenpenny Tower until it meets your robo-butler. Then it tries to kill him. Killing the deathclaw causes it respawn, friendly to you and hostile to the robot, on its own corpse every few days.
 * A controlled Deathclaw has appeared on the way to Roy Phillips' hideout when entering from the Warrington Station entrance. It materializes near the player and cannot be seen from afar.


 * (X-box 360) Mind controlled deathclaws will sometimes not even leave their cage when interacted with.
