Preparation And Inspection For Use; Inspection Of The Video Processor - Pentax ED-3490TK Operation Manual

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:
NOTE:
PENTAX 90K series video endoscopes contained in this manual are only compatible with PENTAX video
processor model EPK-i or EPK-1000.
CAUTION:
To avoid discontinuation of the endoscopic procedure, have an extra (spare) instrument available as a standby
device. Should any unforseen event or circumstance render the original instrument inoperable and/or unsafe for
patient.

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) Mount the water bottle assembly within reach of the air pump fitting on the video processor and the air/water port on the PVE
connector of the endoscope.
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. Additionally, 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.
air/water feeding tube
6) Connect the air/water feeding tube from the water bottle 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 turn ON the lamp.
9) Prior to each procedure, check the endoscope image quality displayed on the monitor. Confirm that the image quality, color,
automatic brightness (iris) functions are acceptable as per the instructions provided with the PENTAX video processor.
2) Plug the processor into a properly grounded receptacle with
the power switch in the OFF position.
3) Make sure that the PENTAX PVE connector is aligned with
the interface socket on the front panel of the processor.
4) Connect the endoscope to the interface socket on the

processor as illustrated.
5) Rotate the lever of the interface socket clockwise after
insertion.
CAUTION:
After connecting the endoscope to the EPK-i video
processor, always make sure that the endoscope is
firmly secured to the scope receptacle by turning the
locking lever to the "lock" position.
