When in stand-by , the DTR displays the following message :
Here, we can select one of the five mentioned groups. For selecting a different group, we need to return to this
display and then press the corresponding key.
Once inside a group, we cannot select another group without exiting and going back to the stand-by screen. We can
move inside a group using ENT, CLR, ↑, ↓, ← & → keys. They are used as follows:
ENT : Accept the option that is on the display in that moment. It is the same as descending one level in the menu
tree.
CLR : Exit the option on the display. It is the same as ascending one level in the menu tree.
↑/↓: Change option. It is the same as a horizontal movement inside a menu. When we find the desired option, we
can select it with ENT.
←/→: These keys show the different possibilities of a certain setting. When we find the desired option, we can select
it using ENT.
