5 Adjustment of the Eyepieces

You must adjust the eyepieces to your interpupillary distance (IPD). IPD means the distance between your eyes.

5.1 To Adjust the IPD (5C)

A. Turn on power by pressing the switch on the base.

B. Turn the black Rheostat Knob on the left to adjust the light intensity.

Light will project from upper part of the Colposcope.

C. Gently place your eyes against the black rubber eyepieces.

Grasp the metal housing with both hands. Gently rotate the barrels together or apart.

D. A singular circular image should be seen through both eyepieces.

This adjustment is similar to adjusting the eyepieces of binoculars.

6D and 6E

6 Adjustment of the Diopter Knobs

Set the Diopter Knobs

B. Turn the colposcope on, place your eyes against the eyepieces, and focus the colposcope on a

fixed object until that object appears clear and sharp.

C. It is recommended to focus on letters such as a book or a magazine. Do not focus on an object

like a piece of fruit.

D. Close your right eye. With your left hand, rotate the Diopter Knob until the object is clear and

sharp for your left eye. Note: The Diopter allows you to adjust for plus and minus vision

corrections.

E. Then close your left eye. Rotate the right diopter knob with right hand

until the object is clear and sharp for your right eye. Note: The Diopter

allows you to adjust for plus and minus vision corrections.

F. It is important to keep a record of the adjustments on the

Diopters for both your left and right eyes. Since most offices have

multiple people using the Colposcope, the eyepieces will be

different when someone else wants to use it. By remembering

your diopter settings, clarity can be achieved by simply moving the diopters to your

setting when you are ready to use the Colposcope. This avoids you going through steps

A–E each time.

zero.

G. You will see two measuring circles through the lens. Since your Colposcope has three different

magnifications, the measurement at the tissue site will vary according to the magnification you’re

using. The reference chart gives you the correct size per magnification change.

Note: There is

a chart on the right metal housing.

7 Colposcope Instructions for Use

The following briefly describes using the Colposcope with a patient. It is recommended that you practice using the Colposcope to familiarize your- self with all of the features it has to offer.

A. Let patient in a supine position.Your

Colposcope should be placed so that the head of the scope is 300mm from the area you wish to view, with the post to as near

vertical as possible. Rotate the Gross Height

Adjustment and Locking Knob to loosen it and move the inner post up or down. Tighten the knob to lock the inner post in place.

B. In a sitting position, place your eyes against the eyepiece. Adjust for pupillary distance and make sure that you set your correct diopter reading. Place your right

hand on the Fine Height Adjustment Handle

and your left hand on the Fine Focus Handle. Note: Do

not try to focus with Fine Focus .

C. With your hand on the Fine Height Adjustment

Handle, slowly push or pull the Colposcope, until the

field comes into view.

D. Adjust the Fine Focus Controls to provide clear, magnified views of the area to be examined. Rotate your left hand on the Fine Focus Handle which will finely move the optics towards or away from the object that you wish to view. Also, rotate your right hand which

is on the Fine Height Adjustment Handle up or down to

raise or lower the optics. Adjust light intensity rheostat as needed by turning the black Rheostat Knob. Turn the silver Green Filter Knob for optimum assessment of affected area.

Note: Both the black Rheostat Knob and the silver Green Filter Knob are conveniently located on the

8E. Pull the Fine Height

Colposcope head, thus allowing the user complete control without looking up from the eyepieces.

E. The Colposcope head may be tightened or loosened according to your preference by turning the Head Inclination Adjusting Knob.

Note on all photos All 1 step colposcopes use the same adjustment techniques as

shown on these pages, although models shown may differ.

8 Selecting Your Preferred Level of Magnification

The ALLTION offers you the advantage of magnification during a colposcopic examination.

A. When viewing the cervix, reach up and rotate the Three-Step

Magnification Knob.

B. Rotate it to your desired magnification(3.75, 7.5, or 15).When

moving from one magnification to another, slight adjustments

in the fine focusing mechanism might be necessary.

C. Turn the Fine Focus Handle.

If patient is not centered, you can move the Colposcope head in

multiple directions to change your field of vision. See photos D–F.

9 Integrated Video Camera

An integrated video camera (1 CCD) is available in specific models.

It is very convenient for the doctors to communicate with the patient by this device.

1.CCD camera power: connect the black wire(3) from the bracket to the camera socket in the head.

2.Video Output：Connect the attached HDMI line to the HDMI port (1) in the head, and then connect the other end of attached HDMI line to the HDMI port of TV or Monitor AV adapter.

3. Internal CCD Camera: The images from integrated video camera can be inputted into a monitor or a TV set directly. Or it can be inputted into a computer by image collection with USB 3.0

HDMI adapter or stored into a hard disk recorder

10 Storage and Precautions

A. For storage, the instrument should be placed in a clean, dry environment with stable temperatures to extend the life of the components and ensure longevity of the instrument.

B. Please cover the Colposcope with the plastic dust cover that is included with this instrument. This will keep the optics and components relatively dust free.

C. When storing or carrying the instrument, adjust the instrument to the lowest position. This will help ensure that if it is inadvertently hit, it will resist tipping over.

11 1Moving the Colposcope

Rotate the Gross Height Adjustment and Locking Knob to move

the post to a comfortable position.

Tighten the Gross Height Adjustment and Locking Knob.

Place your foot between the wheels at the front end of the base.

With your hand on the Fine Height Adjustment Handle,

pull forward and roll across the floor.
