the requirements of 4.5.2.3.3 shall be utilized for this test. The force
(pull) required to disengage the diopter knob from its lock position shall
be within the values specified in 3.7.1 for the temperatures indicated.
4.6.9 Diopter knob rotation. - Testing equipment conforming to the
requirements of 4.5.2.3.4 shall be utilized for this test. The running
torque required to rotate the diopter knob throughout its range of
movement, in its unlocked position, shall be within the ValueS specified
in 3.7.2 for the temperatures indicated.
4.6.10 Filter transfer lever. - When the telescope is thermally
stabilized at -65 and +150F the filter transfer lever shall be subjected
to a tactile inspection. The filter transfer lever shall conform to the
requirements of 3.7.3 at each extreme temperature.
