Operation; Power Switch; Lamp Ignition; Focus And Zoom Controls - Welch Allyn 88002 Operating Instruction

Operation

Power Switch

With the power cord connected to a properly grounded outlet, and the S-video cable connected to the video colposcope and
monitor, activate the power switch on the handle of the video colposcope.

Lamp Ignition

Once the video colposcope's power switch has been activated, the lamp will ignite. The lamp requires approximately 11
seconds to warm up.

Focus and Zoom Controls

Once the power switch has been activated, the video colposcope will execute a setup procedure, ending in the low
magnification setting, or 4.5x. To obtain coarse focus, position the distal end of the video colposcope approximately 300mm
from the target. Adjust the video colposcope by moving the stand (for vertical stand), or the arm (for the swing arm stand),
until the picture is in focus. Press the + on one of the zoom controls until maximum magnification is obtained, and readjust
the position of the stand or the swing arm until the picture is in focus. Fine focus, in either direction, is provided by the
focus controls once coarse focus has been achieved. After coarse focus is achieved at maximum magnification, zoom control
can be set to a desired lower magnification by pressing either zoom control. Focus will be maintained throughout the entire
magnification range once these steps have been completed if the video colposcope or target is not moved.
Note: The setup (nominal) setting of the focus controls can be recovered by pressing one of the zoom + controls for 4
seconds after maximum magnification has been achieved.

Green Filter Controls

Activate the electronic green filter by pressing the green button located on either side of the video colposcope. Full
activation of the green filter occurs in less than 10 seconds. Deactivated the filter by pressing the green filter button again.
The green filter LED indicator flashes during activation and deactivation and remains on after activation is complete.

Illumination Beam Director

The illumination beam director can be rotated up to 45° clockwise or counterclockwise to better illuminate the examination
area. To rotate the director, grasp the flat sides and twist in either direction as desired. The illumination beam director moves
with some resistance. This helps to hold it securely in the desired position. The center position can be recovered by returning
the director to the detent position.

Vertical Height Adjustment Ring

The height of the vertical stand can be adjusted by rotating the black height adjustment ring, located on the pole of the stand,
counterclockwise. Once the ring has been loosened, adjust the pole to the desired height and then tighten the ring again by
rotating it clockwise.

Swing Arm Height Adjustment

Adjust the height of the swing arm stand by loosening the height adjustment knob located on the arm of the stand. The swing
arm can then be moved to the desired position. After moving the arm, tighten knob securely by rotating clockwise. The
desired drag can be obtained by adjusting this knob either clockwise or counterclockwise.

Positioning Video Colposcope

The video colposcope can be angled up and down and left and right. To change the up/down tilt angle, loosen the knob
located on the tilt axis. The video colposcope can then be tilted as necessary. To change the horizontal angle, loosen the
knob located on the support shaft. The drag of either knob can be set by loosening or tightening as necessary.

Remote Video Functions

The handle of the video colposcope contains three buttons that control three video functions. These functions, provided by a
remote video printer, are Freeze, Print, and Toggle. (See Connection Diagram section of this manual for connecting the
printer to the video colposcope.)
1. Pressing the freeze ("F") button stores a new image in printer memory. The frozen image is displayed on the monitor.
2. Pressing the copy ("C") button prints the image displayed on the monitor. If live video is displayed, the image visible
when the button was pressed will be printed.
3. Pressing the video ("V") button changes the display from printer memory (frozen image) to live video, or from live video
to printer memory (frozen image), depending on the current mode.
