to the EPK- 700. The adapter, AE-P1 is already attached to the
EPK-700.
-Connecting a video endoscope without a light guide
adaptor in place will reduce light output at the endoscope
distal end. Attempting to connect a fiberscope without a light
guide adapter and/or an appropriate light guide sleeve in place
will damage the fiberscope and the EPK-700.
2. Check to ensure that the scope locking lever is open.
3. Connect the scope light guide into the processor.
4. Connect the scope electrical connector into the processor.
5. Close the scope locking lever
-If using the fiberscope video adaptor module, make
sure the eyepiece of the fiberscope is properly connected to the
module (use adapters as required). Connect the electrical
connector of the module to the electrical connector of the EPK-
700, lining up the red dots on each.
6. Connect the water bottle Air/ Water connector to the
Air/Water receptacle on the endoscope’s umbilical connector.
7. Connect the suction tube of the suction device to the suction
nipple on the umbilical connector of the endoscope.
(4) CONNECTING THE PERIPHERAL
EQUIPMENT
1. Referring to the rear panel diagram, connect a TV monitor to
the EPK-700

4-2 PRE-USE SAFETY CHECKLIST
WARNING - Before every use the following points should be
checked. If any function or device in the video endoscope system
does not perform properly, DO NOT perform the endoscopic
examination. Contact the manufacturer of the device, your
Pentax sales representative or a Pentax service center before
using the equipment for an endoscopic examination.
1. Ensure video processor is placed in stable and level position.
2. Ensure water bottle is properly prepared and connected.
3. Ensure endoscope (and fiberscope video adaptor module if
applicable) is connected properly.
4. Ensure EPK-700 lamp life is less than 200 hours. If lamp life
is 200 hours or more, contact your Pentax sales representative
or a Pentax service center to replace the lamp.
5. Turn ON monitor and other peripheral devices.
6. Turn ON EPK-700 power switch. Ensure switch is lighted
green, the lamp is ignited and the sound of the ventilation
fans can be heard.
- Always turn ON the processor AFTER connecting
an endoscope.
Power function switches should not be motivated by contact
with objects like endoscope light guides, when being switched
ON or OFF.
When power is turned OFF, wait 60 seconds before turning
power switch ON. Failure to do so may compromise the
functionality.
Before turning the EPK-700 power ON, ensure the air flow
vents are not obstructed.
7. If lamp fails to ignite, turn EPK-700 OFF, wait 60 seconds
and repeat steps 6 and 7.
-If lamp fails to ignite, DO NOT attempt to perform an
endoscopic examination, contact your Pentax service facility.

9. Exercise the endoscope’s automatic iris. Bring the tip of the
endoscope within 1 cm of 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 the light is being emitted from the distal
end of the endoscope.
10. Check the endoscope control buttons positioned on the
control body of the endoscope. Each button; F, C and V
will beep when pressed.
11. Select brightness control auto or manual. If selecting
AUTO, also select light measurement mode, average or
center. And exercise the brightness control buttons to
ensure the brightness indicator and controls are functioning.
12. Exercise the color adjustment as described below.
-Allow the processor to run for ten (10) minutes with
main lamp ON before adjusting colors.
Cup the distal end of the endoscope loosely in your hand.
Ensure that the monitor displays a natural color. Exercise the
color adjust buttons (Red Up and Down and Blue Up and
Down) to ensure the changes are recognizable in the image of
your hand. Remember, the 0 values are considered standard and
all color adjustments should be made with that in mind.
13. 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.
14. Turn ON the air pump. The switch LED will light and the
sound of the air pump should be heard.
15. 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.
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.
