Mio MIOMAP C220 - Manual (Page 72)

6.1.6.1 Audible Warning
You can disable the audible warning; have a simple warning (when you are warned
only if you exceed the speed limit when approaching a camera); or a complex sound
with repeated beeps as you approach the camera. In case of section control
cameras, you will also hear these beeps while you are between the two cameras
(these cameras work in pairs).
You are warned well in advance. The distance MioMap starts warning you before
reaching the camera depends on your speed. The higher the speed, the earlier the
warning starts.
6.1.6.2 Visible Warning
Besides this, MioMap can pop up a visual warning with only the symbol of the
camera above the speed limit sign on the Cockpit screen, or you can ask for details
as described below.
Approaching a fixed or built-in camera you will see the speed limit checked by the
camera, and the remaining distance to reach the area monitored by the camera.
With mobile cameras you can only see the distance from the measured area, as
there is no speed limit set.
When approaching the first of section control camera pairs you will see the same
data as with a fixed camera (speed limit and distance). Then while being between
the two cameras, your frequently updated average speed is displayed below the
speed limit.
