4.3. Connecting instruments
 Before connecting instruments, ensure that the following conditions are met:

Accessory combinations not mentioned in the operating manual
may be used only if they are explicitly specified for the intended
use. Performance features as well as safety requirements must
always be taken into account.

The insulation of the accessories (e.g. HF cables and instruments)
must be sufficient for the maximum output peak voltage (see
IEC 60601-2-2 and IEC 60601-2-18).

Accessories with defective insulation may not be used.
4.3.1. Use with flexible argon probes
Connect the connection cable with the flexible probe to the monopolar output of
the HF device. After the system has been purged with argon gas by touching the
Purge button, coagulation can be activated with the blue foot switch.
The ARC generator shows the gas flow rate and the fill levels of the argon gas
bottles on the display when the HF generator is properly connected to the ARC
PLUS.
Recommended settings:

25 W Argon Flexible mode on HF device

0.4 l/min Coag Flow on ARC PLUS
Perform a functional test before inserting the flexible probe into the working
channel of the endoscope. To do this, immerse the tip of the probe in water and
press the Purge button. If the equipment is working properly, the emerging gas will
form bubbles. Also check the instruments for visible external defects.
For information regarding use with flexible argon probes and for recommended
settings, see the operating instructions for the instruments.
4.3.2. Use with rigid argon probes
Connect a handpiece with suitable electrodes to the monopolar output. After the
system has been purged with argon gas by touching the Purge button, the argon-
assisted cutting or coagulation current can be activated by pressing the yellow or
blue finger switch on the handpiece. The ARC generator shows the gas flow rate
and the fill levels of the argon gas bottles on the display when the HF generator is
properly connected to the ARC PLUS.
Recommended settings:

80 W coagulation power, Argon Open mode,
or 100 W cutting power; Argon Open mode, on HF device

3.5 l/min Coag Flow or 4.0 l/min Cut Flow on ARC PLUS
