WARNING:
From the standpoints of infection control, accessories which ENTER
STERILE TISSUE, THE VASCULAR SYSTEM, BLOOD VESSELS, or MUCOUS
MEMBRANE must be sterile.
WARNING:
For ALL types of endoscopic accessory instruments, always maintain a
view of the accessory during advancement, use, and withdrawal of the
device.
Incautious use of EAI devices could end up damaging patient tissue/
membrane or perforation.
CAUTION:
Because of the effect accessories used in the instrument channel of the
endoscope can have on the performance of the endoscope itself, it is
strongly recommended that only PENTAX accessories be used with PENTAX
endoscopes. If a unique or highly specialized accessory is available from
another source, the accessory manufacturer should be consulted to
confirm compatibility with PENTAX endoscope before use.
CAUTION:
For safety reasons, always insert and advance the accessory in the
standard, non-magnified mode.
Magnified vision reduces the depth of the viewing field making it difficult to
maintain a clear view of the accessory.

1) Insert the forceps through the slit in the inlet seal. Be certain to hold the forceps
handle in such a way to ensure that the cups/jaws of the forceps are in a fully
closed position during insertion.
NOTE:
When the cups/jaws are first passed through the inlet seal, a temporary
resistance will be encountered.
Hold the shaft tightly at about 5cm from the cups/jaws and push it
through. During insertion, if the forceps are found hard to advance further
due to resistance, decrease the angulation of the bending section to a level
suitable for smooth insertion and insert the forceps again.
