please note the following: If you use an electrosurgical device
and an endoscope that is supplied with energy at the same time,
the low-frequency currents from both power sources accumu-
late to form one single patient leakage current. If the electrosur-
gical device belongs to type CF and the endoscope to type BF, the
less favorable limit values for type BF apply to the overall patient
leakage current. You should therefore only use power sources
with the same type classification, ideally those of type CF.

Risk of burns to the patient
The distal end (1) of the APC probe should protrude at least 10
mm out of the distal end of the endoscope. This is ensured when
the first black ring (2) on the distal end of the probe is visible
through the endoscope.

4.10 Danger of burns
Argon plasma can strongly heat electrically conductive materials,
e.g. metal. To avoid burns, never direct argon plasma towards
electrically conductive materials.
