clear reading.

4. Make a note of your IPD measurement. You may want to recheck several times to make
sure your reading is accurate.
You can also ask a friend to help you measure your IPD instead of doing it by yourself with a
mirror. Make sure you're looking straight ahead while they measure.
Estimating your IPD through experimentation
You can estimate your IPD through trial and error. This method is easier than using a ruler, but it
may be less accurate.
1. While wearing the VR headset, focus on text or lines at the center of view. If there isn't any
text in your field of view, open a screen that has some text on it.
2. Adjust the IPD slider until the text is clear. Note the number for future reference.
3. If the image is clearer for one eye than it is for the other, adjust the headset position.
Repeat until the image is clear for both eyes.

What should I do when the headset is unable to detect the controllers?
Once paired with the headset, the controllers will automatically be detected when turned on. If
you don't see the controllers while using your headset, consult the following:
§ The controllers may be in sleep mode. Shaking them gently will wake them.
§ If your controllers are off, turn them on by pressing the VIVE button
controller and the Menu button on the left controller. The controller LEDs will turn blue
while they are connecting, and then green after they're connected.
§ If the controllers aren't detected after the firmware is updated, press and hold the VIVE
and Menu buttons to restart both controllers.
§ Make sure your controllers are charged. A flashing red LED indicates a low battery. If the
controllers have low battery levels or don't respond, try charging them. For details, see
VIVE Controller for XR Series
§ If your controllers are on but still not being detected, you might need to pair them again.
