nification setting. This procedure will allow the image to stay
in focus throughout the full range of magnification during the
entire procedure. You will only lose focus if either the colpo-
scope or patient is moved.
IV. Fine Focus
Use of the fine ‘focus’< > controls is recommended ONLY for
visualization at high magnification where the depth of field
is 5 mm, or for inspecting the endocervical canal or vaginal
fornices. Once focus is achieved (Section III), at high magnifi-
cation, simply depress the ‘focus’ < > until the area of visual-
ization is in focus.
Note: To “reset” the focus back to its original setting when
the colposcope is first turned on, press and hold one of the
‘zoom +’ controls for 4 seconds after maximum magnification
has been achieved.
V. Taking a Biopsy
Once you have selected the appropriate magnification set-
ting, pull the video colposcope away from the patient until
the image is just out of focus. Press the fine focus forward
control ‘focus >‘ until the image is in focus. This process
will maximize your working distance for biopsy. Insert the
forceps in the usual manner, then guide the instrument on
the video monitor.
VI. Using the Green Filter
To use the electronic green filter, press the green filter button
located on the left side of the video colposcope. The LED will
remain lit while the green filter is on. To deactivate the filter,
press the green filter button again.
VII. Mag Index Control
To activate the Magnification Index
control, press the blue button located
on the right side of the colposcope.
To deactivate the Magnification Index
control, press the blue Mag Index
control button again.
VIII. Polarization Filter Control
The polarization filter can be rotated
to reduce the glare from the image.
The filter is completely engaged (minimum glare) when the
control is fully rotated to the left. The filter can be disen-
gaged by fully rotating the Polarization filter control to the
right.
