System Settings and Alarms:
The P10 HUD allows you to set various parameters for over-limit alarms to improve driving safety.
Figure 9: System setting menu showing options for Over Speeding reminder (default 150 KM/H), Engine temperature alarm (default 120°C), Engine RPM alarm (default 6000 R/min), Voltage alarm setting (default 10.5V), Speed error adjustment (default 107%), Voltage error adjustment (default 100%), and Engine displacement setting (default 1.6L).
The device also features an intelligent reminder system where the speed display color changes based on your speed:
- 0-99 KM/H: White display.
- 100-119 KM/H: Yellow for reminder.
- 120+ KM/H: Red for alarm.
