Line of Sight

The Swivl base will follow the movement of the marker using an infrared signal. For best results, the marker must maintain a relatively direct line of sight with the Swivl base and we recommend using a table or floor stand. The marker will function at a range of 3-30 feet from the base, but a distance of 5-20 feet is preferred.

We recommend that you practice moving around a room using the infrared signal. You may notice that the infrared signal may even reflect off of smooth, shiny surfaces or become blocked by a loose sweater or tie.
