4. Adjusting Focus and Pupillary Distance
To achieve the clearest image, adjust the pupillary (focal) distance by rotating the lenses. You can also adjust the lens position by sliding the buttons located on the bottom of the headset. Experiment with these adjustments until the image is sharp and comfortable for your eyes.
5. External Controllers
Many VR games and applications require interaction beyond head movements. For a complete experience, an external Bluetooth controller (sold separately) may be necessary, as the headset does not include a built-in touch button or stylus.
Maintenance
Cleaning the Lenses
Use a soft, dry microfiber cloth to gently wipe the lenses. Avoid using abrasive cleaners or solvents, as these can damage the lens coating. Do not touch the lenses with your fingers.
Cleaning the Headset Body
Wipe the exterior of the headset with a slightly damp, soft cloth. Ensure no moisture enters the internal components.
Storage
Store the headset in a cool, dry place away from direct sunlight and extreme temperatures. Keep it free from dust and debris.
Troubleshooting
Blurred Image

- Adjust the pupillary distance and lens position using the controls on the headset.
- Check if your smartphone screen is clean and free from smudges.
Discomfort During Use
- Adjust the headband straps for a more comfortable and secure fit.
- Take breaks during extended use to prevent eye strain or dizziness.
