For this the “<” and “>” buttons may be used to select the parameters and the “+” and “-” buttons to select between “-”, “1” and “2”.
The
settings become effective
when the
fi
lter table is compiled. This is done using the “<” and “>” buttons; select the
“Compile”
parameter and use the
“+”
or
“-”
buttons to initiate the compilation of the channel table.
The menu is exited by pressing the “Sub-menu”
button. If this brings you back to “Transport stream processor” in the sub-menu,
this can be exited only when the cursor is on the
fi
lter's “On/Off” parameter.
