Front Panel Buttons
With the exception of the power button, all front panel
buttons have specific colored labels on them. They
are all marked in black, blue or orange color. Each
color has a specific representation, as described
below:
Black—the primary function, meaning that
function will be set or configured upon pressing it.
Orange —the secondary function, it means that
the function will be set or configured if that button is
pressed and hold down for 2 seconds.
Blue —the utility function, the function will be set
or configured if the UTIL button is pressed and hold
down for a long time. See “Utility Menu” section for
details.
NOTE:
In the button operational instruction, we
will use the button name to express the button
operation without differentiating the type of button;
Pay attention to the difference between “long press”
and “press”.
