The HTC Vive HMD (head-mounted display) and controllers are not being tracked properly. What should I do?

Adhere to the following guidelines to ensure proper functioning of the HTC Vive tracking system:

• Blocking line-of-sight between these base stations and the player will disrupt tracking, so never stand in front of the tracking stations or block their line-of-sight.
• Avoid interference from a second pair of base stations in the vicinity. Only use one pair of base stations for your Omni(s).
• Avoid reflective materials like mirrors, shiny floors, or shiny wall objects around the Omni.
• Avoid excessive sunlight.
• Remove the plastic film that covers the front of the base stations when shipped.
• Mount the base stations as high as possible (the higher, the better) and point them towards the floor at a 60-degree angle, making sure they provide enough coverage for the players.
• For improved tracking and less interference, connect the two base stations via the included syncing cable (A/B connection). Not applicable to Vive Pro base stations.
• Do not move the base stations after you have positioned them and run room setup.
