Keep your eyes away from the distal end when inserting
EndoTherapy accessories. Extending the EndoTherapy
accessory from the distal end could cause an eye injury.
1. Insert the EndoTherapy accessory through the biopsy valve. Confirm that
the EndoTherapy accessory extends smoothly from the distal end. Also
make sure that no foreign objects come out of the distal end.
2. Confirm that the EndoTherapy accessory is withdrawn smoothly from the
biopsy valve.
Inspection of the zoom function
 For CF-H260AZL/I
1. If the magnification controller is OFF, turn it ON and set the speed mode as
described in its instruction manual.
2. Move the zoom lever toward “ T”. After about 3 seconds, confirm that the
image of an object located about 2 mm from the distal end is clearly visible.
3. Move the zoom lever toward “W ”. After about 3 seconds, confirm that the
image of an object located at about 20 mm from the distal end is clearly
visible.
4. While observing the palm of your hand, move the zoom lever toward “ T”
and confirm that the endoscopic image changes smoothly the wide-angle
image into the magnified image.
5. While observing the palm of your hand, move the zoom lever toward “W ”
and confirm that the endoscopic image changes smoothly the magnified
image into the wide-angle image.
• Immediately after turning the magnification controller ON, a
widest angle image will be observed.
• If the endoscope is stored at a temperature lower than room
temperature, the speed of the magnification control could be
slow. In this case, wait for a moment until the endoscope
reaches room temperature and check the magnification
control function again.
