CAUTION:
It should be noted that as long as the valve of the CO
2
gas cylinder is OPEN
and the hole at the top of the Air/Water feeding valve is NOT covered,
CO
2
gas will constantly be vented through the Air/Water feeding valve
into the room. To reduce excessive CO
2
concentrations, it is, therefore,
recommended to close the CO
2
gas cylinder valve, work in a well ventilated
room, and use air delivery whenever possible during examinations which
are lengthy or in very conned quarters.
As an alternative, the optionally available gas/water feeding valve, model
OF-B194, may be used in place of the standard air/water feeding valve.
OF-B194 is a closed two-stage valve mechanism.
Pressing the rst stage delivers CO
2
gas and depressing the second stage
activates water delivery.
CAUTION:
Prior to performing electrosurgery, make sure that the electrosurgical
device exits the distal channel opening of the endoscope. Failure to conrm
activation and deactivation of the electrosurgical device could result in
endoscope damage.
2) The electrosurgical devices should be introduced through the endoscope in the
same manner as described for biopsy forceps in section 3-4.
WARNING:
To avoid user burn and/or severe damage to the patient, follow the
instructions below before high frequency energy is delivered.
1) Use only the electrosurgical systems with the floating grounding
type (Type BF or Type CF). Do not use the non-floating (Type B)
electrosurgical systems.
2) There are two types of Floating Ground Electrosurgical Generators. The
operator should conrm if the Floating Ground Electrosurgical Generator
requires an endoscope feedback cord (s-cord).
For Floating Ground Electrosurgical Generators which require an s-cord,
connect the s-cord between;
the endoscopes feedback terminal and
the Electrosurgical Generator patient ground connecting socket.
For Floating Ground Electrosurgical Generators which do not require an
s-cord;
DO NOT use the s-cord, to avoid potential patient injury.
use the Condenser Earth Cable, OL-Z3 to reduce interferences or noise
that may appear in the video image.
If the video processor does not have an equipotential terminal, do not
connect any functional ground cord.
3) High frequency energy should be delivered for as short a time period as
necessary to accomplish the desired clinical effect.
Select a high frequency output power setting suitable for the
particular intended procedure in order to avoid thermal invasion of the
tissue or insufcient coagulation. Otherwise, it will result in excessive
bleeding.
