It had a transportation range of ten light years. Although incredibly powerful and precise, the translocator could only transport one person at a time at its maximum range. At this range, the translocator was limited to simultaneous transport of one person to and one person from a location. The translocator can, however, transport multiple at closer ranges as was said by Dammar when he planned to use it to transfer his entire security force at once.
The Nyrians employed the device to gradually replace the crew of a vessel. Initially they claimed to be surprised by their sudden relocation, but, when sufficient numbers of Nyrians were aboard, they would take over the vessel and remove the rest of the crew. The main control of the translocator was found on the Nyrian biosphere vessel and it was there that the removed crew were placed. The device was permanently disabled in late 2373 by crew of the USS Voyager. (VOY: "Displaced")
By 2374, the pirate Tau had stolen the translocator technology for himself. He used the translocator to steal large quantities of technology from Voyager. To beam the mobile emitter, the main computer processor, a site-to-site transporter, the warp diagnostic assembly, five tricorders, three phaser rifles, photon torpedo casings, two antimatter injectors, and a supply of emergency rations, Tau had to transport the items from extreme close range and destabilized the shield perimeter of Voyager with weapons fire. The crew of Voyager was able to devise a means of blocking the translocator after the theft. (VOY: "Concerning Flight")
