Solution:
1. Press the glasses button once or raise your head to wake the display. Make sure HUD is enabled in the app.
2. Make sure the glasses have sufficient battery power. The display may not turn on when the battery is critically low.
3. If there is still no response, connect the charger and charge the glasses for 1 hour before trying again.
4. Try restarting the glasses or restoring them to factory settings.
