1. Normal Display – Speedometer
The backlight is blue, as default it shows vehicle speed in MPH, which is measured
by the GPS.The speed is updated every second, and at a constant speed is highly
accurate.
When quickly accelerating or decelerating, the display will lag the actual speed by
a small margin. It’s rare to find a vehicle that shows the same speed as ROAD
ANGEL.This is due to all vehicles being manufactured with a tolerance on the
speedometer to allow for tread depth, tyre size and pressure changes.
Once acquired the satellite coverage can be monitored by the bars on the right
hand side of the display, the more bars shown the greater the coverage.
2. Alert Display
ROAD ANGEL can warn the user of 6 different types of warning. When alerting
of an approaching zone the type of zone is shown on the display as a picture.
When a stored location is approached the display will turn from blue to red with
the type of warning shown on the display.The unit will give both voice and beep
alerts and the first bar of the proximity will count up.As the location is neared,
the bar chart will count up and the beeping frequency is increased.
