Rotary Knob
1 The rotary knob is the main control used to
select and confirm all monitoring and system
settings.
– Turn the rotary knob to change or select a value
or parameter (clockwise rotation increases a
value; counterclockwise rotation decreases a
value). This function is indicated in the exam-
ples and instructions in this manual by “select.”
– Press the rotary knob to set a value or confirm
a selection. If the selection is not confirmed, the
value or parameter will not change. This func-
tion is indicated in the examples and instruc-
tions in this manual by “confirm.”
