– Main monitors cannot monitor the outside with the lobby stations.
– When receiving an incoming call from a lobby station, the images from lobby stations are displayed in the
main monitors of the room units, and the lobby station group number of the lobby station is displayed in the
image. With the VL-MVN511 for example, if images from a lobby station in lobby station group 1 are displayed,
