Important Notes

1. This device operates on 5V USB power only. Do not use a power source higher than 5V, as this will damage the internal components.
2. There is no built-in battery inside the unit. It only works when connected to an external power supply.
3. First-time use may take 1–2 minutes to acquire satellite GPS signal. Signal acquisition is faster in open outdoor areas.
4. For the clearest projection effect, clean the windshield thoroughly before applying the reflective film.
5. Speed data is calculated based on GPS satellite positioning. There may be a slight difference compared to the vehicle’s built-in speedometer, which is normal.
