Hardware
SteamVR Base Station 2.0
SteamVR Base Station 2.0 uses advanced optics to determine the exact location of each VIVE
Tracker (3.0) and Rover module.
§The base stations transmit signals to VIVE Tracker (3.0). Make sure the lines of sight between
the base stations and the VIVE Tracker (3.0) units are not obstructed.
§The signals transmitted by the base stations may interfere with nearby infrared sensors,
including those used by infrared remote controls.

§Do not attempt to force open the base stations for any reason. Doing so could injure you or
damage the product.
§If the front panel of a base station is cracked or damaged, stop using the base station
immediately and contact the VIVE Support team.
