Health and safety warnings
To reduce the risk of personal injury, discomfort, or property damage, please ensure that all users of the headset carefully read the warnings below before using the headset.
Before using the headset
A comfortable mixed or virtual reality experience requires an unimpaired sense of motion and balance. Do not use the headset if you are sick, tired, sleepy, under the influence of alcohol or drugs, hungover, experiencing digestive problems, under emotional stress or anxiety, suffering from cold, flu, migraines, or headaches, or are not generally feeling well, as it may worsen your condition. Consult a doctor before using the headset if you have any conditions that impair your vision or mobility, are pregnant or elderly, have a heart or other serious medical condition, or suffer from seizures, migraines, or psychiatric conditions.
Safe environment
Varjo headsets produce an immersive mixed or virtual reality experience that may distract you and make it hard to see your actual surroundings.

• Before using the headset, clear the area of obstacles and hazards, people, furniture, and any other items that may prevent you from moving freely. Also, check that you have enough space above and around you so that you can extend your arms while using the headset.
• Remember that any virtual objects that you see do not exist in the real environment, and their size and location are not real. Do not attempt to sit or stand on virtual objects or use them for support. Be aware of any real-world objects that might be located behind virtual objects.
• Never use the headset in situations that require attention, such as while walking, bicycling, or driving. Do not use the headset while in a moving vehicle.
• Remember that while you are using the headset, you may be unaware of people entering the area.
• Do not use the headset near stairs, balconies, windows, open doorways, or near any other places where you can fall from.
• Do not use the headset near walls, low ceilings, ceiling fans, light fixtures, open flames, heat sources, breakable items, or any other items that you can collide with or knock down.
• Keep in mind the location of the cables and power cords so that you do not walk on, trip over, or pull on them while using the headset. Do not jerk, knot, or bend the cables or cords.
• Do not handle sharp or otherwise dangerous objects while using the headset.

Discomfort
When using the headset, some people may experience dry eyes, eye strain, eye or muscle twitching, involuntary movements, altered, blurred or double vision, or other visual abnormalities, dizziness, light headedness, disorientation, discomfort or pain in the head or eyes, headaches, impaired balance, impaired hand-eye coordination, excessive sweating, increased saliva- tion, nausea, fatigue, loss of awareness, or seizures and other symptoms of motion sickness.
When you start to use the headset, keep your first sessions short and take regular breaks. If you feel discomfort, stop using the headset and continue only after the symptoms have ended. Do not drive, operate machinery, or engage in other visually or physically demanding activities until you have fully recovered from any symptoms. Consider consulting a doctor if you are not able to see virtual objects clearly and comfortably.
Overuse
Take regular breaks when using the headset. Prolonged use may impact your hand-eye coordination or balance and may cause other negative effects.
Repetitive stress injuries
Use the headset and the controllers in a comfortable position. Do not use excessive force when gripping the headset and the controllers. Do not use excessive force when pressing the headset and the controller buttons. If you experience tingling, numbness, burning, stiffness, throbbing, or other discomfort, stop using the headset and rest until you have fully recovered from any symptoms. If you continue to experience these symptoms, consult a doctor.
Interference with medical devices
The headset may emit radio waves, which can affect the operation of nearby electronics, including cardiac pacemakers, hearing aids, and defibrillators. If you use a pacemaker or other implanted medical device, do not use the headset without first consulting a doctor or the manufacturer of your medical device. Maintain a safe distance between the headset and your medical devices and stop using the headset if you observe any interference with your medical device.
Hearing loss
Excessive exposure to loud sounds can cause hearing damage. When using the integrated speakers or external headphones with the headset, start with the volume at a low level and increase the volume slowly if needed. Do not turn up the volume too high.
Seizures
Some people may experience severe dizziness, fainting, epileptic seizures, or blackouts triggered by light flashes, patterns, or exposure to infrared light sources of an eye tracker even though they have no history of these conditions. If you experience any of these symptoms, stop using the headset and consult a doctor. If you have a previous history with these symptoms, consult a doctor before using the headset. To reduce the likelihood of a seizure, do not use the headset if you are tired.
No eye protection
Varjo headsets do not provide eye protection against impact, debris, chemicals, UV light, other harmful lights, particles, projectiles, or other physical hazards.
Electrical shock
Do not try to disassemble, open, service, or modify the headset, controller, controller battery, or any of the accessories or the power supply unit, as this can lead to electrical shock or other hazards and may damage the headset or the accessories or the power supply unit. For PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the equipment and shall be easily accessible. Use the headset only with USB Type-C power supply unit capable of delivering 60 W (20 V and 3 A) and the headset adapter included in the sales box.

Safety information

To prevent injury to yourself or others or damage to the headset, read this safety information before using the headset.
Wearing the headset
When you put on the headset for the first time, follow the instructions on how to position the headset correctly on your head. The headset is correctly adjusted when it sits comfortably on your head and the image inside the headset is sharp. There should be no pain or pressure on your head, and the cushion should feel comfortable on your face.
When you put on the headset, it will adjust the lenses automatically based on your interpupillary distance. This setting is on by default. We recommend that you keep the setting on. Switch off the setting if the automatic adjustment does not work for you, for example, due to eyeglasses or any conditions that impair your vision. If you switch off the automatic adjustment, you may feel discomfort when using the headset.
Reflective surfaces
Please be aware that reflective surfaces may interfere with positional tracking.
Care and maintenance
Handle the headset and the accessories with care and keep them in a clean and dust-free place.
Sunlight and external light sources
Do not leave the headset or accessories in direct sunlight or strong ultraviolet light. Exposure to direct sunlight can damage the optics and display. Do not shine a laser or an external light source through the lenses.
