This function is used to enable Safe Mode and configure the threshold speed in the navigation unit.

While this is enabled, the user configurable Safe Mode is removed.

 

If Safe Mode is enabled, the following restrictions are applied when the speed exceeds the threshold:

•The driver will be restricted from going to ‘Dispatch’ and ‘Tools’ menus .

•If the driver is browsing a page descending from the ‘Dispatch’ or ‘Tools’ menus, the driver will be taken to the main map page.

•The driver will not be able to read new stops or non-immediate text messages

 

 

Input:

speed : INT (0..2236, default: 2236)

The speed threshold in mm/s. The maximum value of 2236 mm/s is around 8km/hr.

Set this value to 0 to restore the user configurable safe mode.

 

 

 

Returns: INT
