11. Exercise the endoscope’s automatic iris. Bring the tip of the
endoscope within 1 cm off the palm of your hand and move
it to about 5 cm away from the palm. Watch the image on
the monitor to ensure the brightness at both distances is
similar. Lift the distal end of the endoscope to the room
lights, the light being emitted at the distal end of the scope
should lower significantly (dependent on the ambient light
levels in the room). Return the distal end of the endoscope
to point at the palm and ensure that the light is being emitted
from the distal end of the endoscope.
12. Check the endoscope control buttons positioned on the
control body of the endoscope.
- In combination with PENTAX 70K/72K/80K/81K/85K
series endoscopes, the function of each button can be selected
with the scope buttons key on the keyboard.
13. Select brightness control auto or XLUM. If selecting
AUTO, also select light measurement mode, average or
peak. And exercise the brightness control switches to ensure
that the brightness indicator and controls are functioning.
14. Exercise the color adjustment as described below.
Cup the distal end of the endoscope loosely in your hand. Ensure
that the monitor displays a natural color. Exercise the color adjust
switches (Red Up and Down and Blue Up and Down) to ensure
that the changes are recognizable in the image of your hand.
15. If XLUM is intended to be used during the procedure,
exercise the XLUM function. Upon selecting the switch,
LED will light and maximize the brightness level.
16. Turn ON the air pump on/off switch. The switch LED will
light and the sound of the air pump should be heard.
Select desired level, Low or High.
17. Exercise Air/Water delivery through the endoscope.
Covering air venting hole on top of Air/Water button
lightly should deliver air at the distal end of the endoscope
by submerging the distal end in enough water to cover the
tip, air flow will be demonstrated by a trail of bubbles.
Pressing the button all the way down should deliver water
through the tip of the endoscope.
- Use only “fresh” distilled or sterile water for testing
of the endoscope air/water delivery functions.
If all items above appear to function satisfactorily, then the
endoscopic procedure may be performed. If any functionality
above is compromised, do NOT attempt to perform the
endoscopic procedure.
