Read the required angle from the first column, connect the bottom hole to the frame and use the corresponding hole from 0 to
5 connected to the 0.5⁰hole in the bottom MLA Compact to achieve the required angle.
The long ground stack bar is a little more complex;-
There are a number of options that are used to obtain the correct angle; the angle is shown in the first column, having selected
your angle you then look across to the next three column which show you which of the cabinet connection holes "A"(yellow)
from 1 to 4 to use and which of the Frame connection holes "B"(Blue) from 1 to 7 and finally which bracket hole in the bottom
cabinet to use.
For example, if we require a downtilt of 10⁰ we use yellow hole 3, to connect to the 6.5⁰ hole in the cabinet and blue hole 7 right
at the end of the "dog leg"to connect to the flying frame.
Next connect the bar in place. It is instinctive to connect to the frame first however when using the short bar, if you connect to
the frame and let go of the bars they drop down inside the gap between the plates of the flying frame and it is difficult to recover
thyem. Connect to the cabinet first, note that you will probably have to remove the rear bracket flying pin from both sides to get
the rear bracket swing arm out of the way before attaching the ground stack bar;-
