2) Inspection of Deflection Controls and Locks
a) Slowly manipulate the Up/Down and the Right/Left
control knobs to see that they function smoothly. Be
certain that a full and appropriate range of deflection is
possible.
b) Engage fully the deflection locks to be certain that the
position of the deflected tip can be stabilized.
