2. PREPARATION AND INSPECTION FOR USE
Prior to use, the endoscope, video processor and endoscopic accessory instruments must be carefully inspected for
cleanliness and proper function to determine that they are appropriate for patient use:
2-1. INSPECTION OF THE VIDEO PROCESSOR
Please refer to the Owner’s Manual of the specific model of PENTAX video processor for complete instructions.
1) Attach water bottle assembly, 2/3 filled with sterile water to the appropriate location on the left side of the
video processor.
2) Set the drain lever on the water bottle assembly to the upright position labeled A/W (air/water).
3) Plug the processor into a properly grounded receptacle with the power switch in the OFF position.
4) Make sure that the PENTAX PVE connector is aligned
with the interface socket on the front panel of the proc-
essor.
5) Connect the endoscope to the interface socket on the
processor as illustrated. Rotate the lever of the inter-
face socket clockwise after insertion.
6) Connect the air/water feeding tube from the water bot-
tle assembly to the air/water port on the side of the
PVE connector.
7) Turn the processor and air pump to the “ON” position and check for proper functioning.
8) Press the lamp switch of the processor to ignite the lamp.
NOTE:
PENTAX video endoscopes contained in this manual are only compatible with PENTAX video processor,
model EPK-1000 and EPK-i.
CAUTION:
To avoid discontinuation of endoscopic procedure, have an extra (spare) instrument available as a
standby device. Should any unforeseen event or circumstance render the original instrument inoperable
and/or unsafe for patient.
WARNING:
The addition of defoaming agents to the water supply is NOT recommended. Due to their nature, these
silicone based agents cling tenaciously to surfaces. Unless they are rinsed very thoroughly, a “barrier”
could be created which could reduce the effectiveness of the disinfection/sterilization process. Addition-
ally, repeated use of such defoamers could eventually lead to residual silicone build up resulting in
equipment malfunction such as clogged air and/or water channels.

CAUTION
Failure to do so may create a “miscommunication”
between the scope and processor and may result
in the loss of the system’s automatic brightness
control and in excessive light emission from the
scope. Excessive light intensity can in turn
increase the amount of delivered thermal energy
causing heating of the scope tip, specifically the
illumination (LCB) cover glass and/or objects in
contact with the distal cover glass.
