Understanding the Display
Standby Mode
In its normal standby mode, ROAD ANGEL COMPACT’s display shows
your speed and compass heading or time, satellite reception (indicated by
a five-bar column – the more bars displayed, the greater the satellite
reception) and the status of audio output:
Speed Measurement
ROAD ANGEL COMPACT calculates your vehicle speed from GPS data.
The speed is updated every second and, at a constant speed, is highly
accurate. If you are accelerating or decelerating, the displayed value will
lag behind the actual speed by a small margin.
You may find a difference between the reading on your vehicle's
speedometer and ROAD ANGEL COMPACT. This is because all vehicles
are manufactured with a tolerance on the speedometer to allow for tread
depth, tyre size and pressure changes.
