SMR Controls 

Maintbook includes functionality to enable the user to include or exclude any one, or a combination of SMR categories displayed in the lower section of the screen. This facility adjusts the pricing across the entire database. 

Both the lower section values and the Display List Running Cost and Pence Per Mile values will change accordingly. When maintbook is re-opened, the SMR Control will revert to all categories selected; if categories are removed a yellow warning marker is displayed in the lower right corner.
