This article provides information on using and troubleshooting the HoloLens™ 2. It covers topics such as safety and care, setup, using the device, and troubleshooting common issues.
Use your HoloLens™ in a safe space, free of obstructions and tripping hazards. Don’t use it when you need a clear field of view or can't commit your full attention, such as while you’re operating a vehicle or doing other potentially hazardous activities.
Keep your first few sessions with HoloLens™ brief and be sure to take breaks. If you experience discomfort, stop and rest until you feel better. This might include temporary feelings of nausea, motion sickness, dizziness, disorientation, headache, fatigue, eye strain, or dry eyes.

This article describes how to resolve several common HoloLens™ issues.
Before you start any troubleshooting procedure, make sure that your device is charged to 20 to 40 percent of battery capacity, if possible. The battery indicator lights located under the power button are a quick way to verify the battery capacity without logging into the device.
HoloLens™ is unresponsive or won't start
If your HoloLens ™won't start:
If your HoloLens™ becomes frozen or unresponsive:
If these steps don't work, please contact Medivis Support at firstname.lastname@example.org.
To ensure that HoloLens™ can see your hands, you need to keep them in the gesture frame. The Mixed Reality Home provides feedback that lets you know when your hands are tracked.
Many immersive apps follow input patterns that are similar to Mixed Reality Home. Learn more about using hand input on HoloLens 2.
NOTE: If you're wearing gloves, note that some types of gloves don't work with hand tracking. A common example is black rubber gloves, which tend to absorb infrared light and aren't picked up by the depth camera. If your work involves rubber gloves, we recommend trying a lighter color such as blue or gray. Another example is large baggy gloves, which tend to obscure the shape of your hand. We recommend using gloves that are as form-fitting as possible for best results.
If your visor has fingerprints or smudges, use the microfiber cleaning cloth that came with the HoloLens™ to clean your visor gently.
Here are some things to try if you can't connect your HoloLens™ to a Wi-Fi network:
The HoloLens™ 2 display is a combination of waveguides and light projectors. Users look through the waveguides—the lenses inside the visor—when wearing the headset. The light projectors are inside the enclosure above the brow. HoloLens™ 2 uses laser light to illuminate the display.
Take the following steps to ensure the highest visual quality of holograms presented in displays:
This section troubleshoots issues with placing holograms, working with spaces, and reporting issues with holograms.
Anytime that you have problems, make sure:
If your holograms don't look right (for example, they're jittery or shaky, or you see black patches on top of them), try one of these fixes:
Reporting issues with unstable or inexact holograms
Please record a video of the issue if possible. This video can be sent to email@example.com and used to help troubleshoot your issue.
Check stability of wifi/router connection. Make sure you are connected directly to the SurgicalAR router and no other devices are connected besides the computer and HoloLens. Also check if there are multiple other wifi networks in the area that will conflict with the signal.
Do a hard reset of the HoloLens by holding down the power button for 10 seconds. Often what happens is there are too many instances of the Viewer open in the HoloLens and they clog up the CPU.
First, be sure that the IP that is displayed in Medivis Viewer in the HoloLens matches that which you entered in the SurgicalAR software. Also be sure that the wifi connection in the HoloLens and the wifi connection on the computer are both connected to the same network
