Wand operation
Control basics
The wand has a distinctive, triangular shape. Each of the three sides has a similar
appearance, and one should be positioned upwards while using the wand.
You can pick up a wand resting on a table or accept a wand handed to you without concern
for which side faces upwards. All three of the control buttons perform an identical
function, but the topmost button should be easiest to press. Pressing two or three buttons
simultaneously has the same effect as pressing a single button.
Powering the wand
Press the power button once to power on the wand, and press it again to turn power off.
The power indicator illuminates when the wand is on.
After the wand is powered, it may take up to 5 seconds for the RF link to be established.
During this time, the wand cursor is not visible on the screen. In some circumstances, it
may take another 10 seconds for the wand’s initial position to be computed. During this
period it is best to keep the wand motionless and the microphones unoccluded.
