When entering this menu area, you will be presented with speed selections 1 through 5.
Each time you press the button to select a number, the
display will scroll faster or slower depending on what setting
you have selected.
In this example, the unit is set to Scroll Speed # 1 which is
the slowest speed. If we were to select # 3 the screen would
begin scrolling faster.
Once you are happy with the scroll speed, select Exit to
save.

When entering this menu area, you will be presented with brightness selections 1 through 5.
Each time you press the button to select a setting, the
display will get brighter or dimmer depending on what
setting you have selected.
In this example, the unit is set to display Brightness 3B
which is the medium intensity setting. If we were to select

lowest intensity.
