What are the starting steps of FSX AEROSOFT A320 weather radar?

There will be no display in the basic working mode (automatic multiple scanning and ground clutter filtering). You can only look at the terrain in manual mode (the antenna angle is negative, receiving all the clutter reflected by the ground). On the left side of the throttle, under the radio, MULTISCAN dials AUTO, GCS dials On, and SYS dials 1 to open.
