power off may damage your hard disk.
Extreme Shut Down
Some extreme events might cause the device to power off. These are ambient
temperature below the low or above the high operating limit or discharged car
battery.
• Internal temperature is beyond the operational limit.
If during operation the internal temperature goes out of the low operational
limits, the display eventually powers off.
• Vehicle battery is discharged.
If, during normal operation, the battery voltage drops below 10.5VDC the
display will provide Low Battery indication (the power indicator blinks
yellow). If the voltage continues to drop, the device automatically powers off
at 8.5VDC.
• Drops in car battery voltage.
If battery voltage drops below the 8.8V limit for 20 seconds or more, the
device will execute critical shut off and power itself off.
