key with the selected settings. This enab-
les you to generate a screenshot on your USB stick by pres-

4 Vertical System
You can select vertical set-
tings using knobs for the ver-
tical position and the sensiti-
vity. You may also use a menu
that is permanently displayed
as well as an advanced menu.
You can select for which
channel you want the settings
to be activated by pressing
the respective channel key
(CH1...CH4). Once a channel
has been activated, the key
will be marked by a colored
LED light. Additionally, the
screen display will include a
frame around the activated
channel with a frame and a color brighter than that of
deactivated channels. The corresponding short menu is al-
ways visible and you can push the Menu
21
key to activate
the advanced menu.
