accessories as described in their instruction manuals.
Ch.4

WARNING
• Do not bring the distal end of the APC probe close to a metal stent. The tissue
around the metal stent may be burned.
• Set the APC unit to the minimum necessary output level. If the output level is too
high, the endoscope's and/or accessory's insulation may be damaged and cause
patient and/or operator burns.
• Before performing APC, inspect the surface of the endoscope for any dents, bulges
or other irregularities. The endoscope may be damaged and cause patient and/or
operator burns.
NOTE
• The outer surfaces of the BF-190 series endoscopes except the BF-XP190 are
insulated. This allows APC to be performed.
• Some Olympus endoscopes are equipped with a feedback circuit to lead leakage
current from the endoscope to the electrosurgical unit. However, the BF-190 series
endoscopes are not equipped with a feedback circuit because leakage current from
the electrosurgical accessory to the endoscope is minimal as the insertion tube is
short. Therefore, the S-cord is unnecessary when using the BF-190 series
endoscopes.
