T-EFN Focus Knob
(supplied with the TE2000-E only. The knob is incompatible with the TE2000-U and TE2000-S.)
The TE2000-E provides focus adjustment in various positions with the supplied T-EFN focus
knob. You can make fine focus adjustments by connecting the T-EFN focus knob to the T-
HUBC HUB controller AUX connector and by switching the knob selector switch on. (Switching
the selector switch off permits fine focus adjustments using the fine movement knob
provided on the right side of the TE2000-E.)
The T-EFN focus knob is comprised of the focus knob main unit and the base plate, which are
connected by a magnet.
The direction of the T-EFN focus knob can be switched between right and left by changing the
main unit's position relative to the base plate. Note that the focus adjustment knob can be
operated independently with the knob facing up.
