Voice Pre - Warnings. This is for the yellow alert and is triggered when the device recognises a bridge but the does not have any height information. Set this depending on the operator's requirement. Some operators prefer only the R-Watch display for this one.
Under Algorithm:
Input all the requested dimensions.
Safety margin of 30cm is recommended - this would mean that If the bridge height is 4.5m then the unit will alarm RED on a height setting above 4.2m.
Green can be enabled which will display a green bridge on the R Watch when the vehicle height < bridge height
