Adjusting the position of the screen
When the screen is open, you can adjust it precisely in different ways:
press the corresponding part of control B to move the screen
towards you or towards the windscreen,
or
push or pull the screen gently by hand.
Storing the position of the screen
The system has four pre-set positions in its memory.
Each time the screen is closed, the system stores the last position of
the screen.
Each time the screen is re-opened, the system returns the screen to the
pre-set position closest to that stored.
