2.2. General safety instructions
Ensure that no electronic devices that are subject to interference
from electromagnetic fields are set up in the vicinity of the HF device.
Observe the instructions on electromagnetic compatibility provided
in section EMC, page 86.
Always connect the HF device to a mains power system with a
protective earth lead in order to prevent electric shock.
Additional devices that are connected to electrical medical devices must satisfy relevant IEC or ISO standards (e.g. IEC 60950 for data processing devices). Furthermore, all configurations must comply with the standardised requirements for medical systems (see IEC 60601-1-1 or Section 16 of the 3rd edition of IEC 60601-1 as relevant). Anyone who connects additional devices to electrical medical devices is automatically a system configurator and thus responsible for meeting standardised system requirements. Please note that local laws prevail over the aforementioned standard requirements. In case of questions, please contact your local dealer or Techical Service, see section Technical service, page 59.
To protect personnel, BOWA recommends the use of a smoke evacuator to extract electrosurgical smoke, e.g. BOWA SHE SHA.

900-301_IFU-V2.2_11316-S0-20131023-EN Operating Manual ARC 250 / 303 19
2.3.3. Safe positioning of the patient
Position the patient so that he is not touching any metal parts that
are grounded or have considerable capacitance relative to ground (e.g. operating table brackets). Lay anti-static towels between the patient and the bedding.
Ensure that the patient does not touch any wet towels or bedding. Place anti-static towels between areas of heavy sweating and skin-
to-skin contact on the patient's trunk.
Ensure that you are using a suitable support surface in order to
prevent pressure necrosis.
Drain urine via the catheter.
2.3.4. Correct connection of the HF device
Always ground the HF device via the equipotential bonding. Also
note the requirements of chapter 8.6.7 of ISO 60601-1 for medical electrical systems.
Do not use any needle electrodes for monitoring. Attach electrodes of physiological monitoring devices without
protective resistors or HF regulators as far as possible from the HF electrodes.
Attach lines from monitoring devices so that they do not lie on the
patient's skin.
Keep the leads to the HF electrodes as short as possible and
position them so that they do not touch the patient or other leads.
Do not place any objects on the HF device.
2.3.5. Correct use of the HF device
Inadvertent activation in the non-visible area of the HF device can injure the patient.
Activate the HF device only when the electrode is in your field of
vision and you can quickly deactivate the HF device at all times.
After inadvertent activation of the HF device, switch off the device
immediately using the on/off switch.
Pay particular attention whenever you use the foot switch or the
manual switch.
Page 20
2 Safety
Lack of preparation, errors in usage or faults in the HF device can cause damage to the HF device.
Use the automatic monitoring functions to ensure that the HF
device works properly without errors. For information on the automatic test functions, see section Monitoring functions, page 29.
Ensure that no conductive fluids (e.g. blood, amniotic fluid) have
penetrated the foot switch or the manual switch.
Ensure that the cables for the foot switch and manual switch are
free from short circuits and broken leads.
2.3.6. Adjusting the settings of the HF device and use of the accessories
Setting the output power too high can injure the patient. Therefore, before you increase the output power, ensure that:
the neutral electrode is correctly positioned,  the working electrodes are clean,  and the plug connections are all correct.
Setting the HF device correctly
To prevent inadvertent (thermal) tissue damage during operations
on body parts with small cross sections and in areas with high resistance (bones or joints), use the bipolar method in these areas.
Set the acoustic signal that sounds when the electrode is activated
so that it is always clearly audible. Nerve and muscle irritations due to low-frequency currents! In electrosurgical applications (particularly applications generating an
arc), a part of the HF current is converted to a low-frequency current. This can trigger muscle spasms in patients.
To minimize the risk of injury to the patient, set the power and
effect as low as possible.
Correct usage of the accessories
Use only insulated accessories. Check all electrodes for sharp edges and projecting parts before
use. Use only electrodes that are free of defects and in good working
order.
Never place active electrodes on or near the patient. Do not remove hot electrodes from the patient's body directly after
cutting or coagulation. Ensure that there is sufficient distance between the patient cables
and the cables of the HF device. Do not run the patient cable across the patient.

2.5. Safe handling (general instructions)
Before each use of the device, check to ensure that it is functioning
properly and is in good working order and connected properly. Observe the instructions for use with regard to standards, see
section Risk levels in the warning instructions, page 14. Always observe and obey the acoustic signals or error indications
during use, see section Error list, page 51. The device and accessories may be operated and used only by
people who have the necessary training, knowledge and
experience. Check the accessories regularly for damage to the isolation, for
proper function, and the expiration date, especially the electrode
cable, endoscopic accessories, and neutral electrodes.
Do not place any instruments on the patients or on the devices. Ensure that no instruments are being cleaned when AUTOSTART
is activated. Wear suitable gloves during operations.
Page 22
2 Safety
2.5.1. Surgical environment: prevention of explosions/combustion
Sparks fly during proper use of the HF device. Do not use the HF device in areas where there is a risk of
explosion.
Do not use any flammable or explosive liquids. If display components fail, do not use the HF device any longer. Avoid using ignitable anesthetics and gases which support
combustion (e.g. nitrous oxide, oxygen) during operations (e.g. in the head and thoracic regions).
Wear suitable gloves during operations. Use exclusively non-flammable cleaning agents, disinfectants and
solvents (for adhesives). If you use flammable cleaning agents, disinfectants or solvents, ensure that they have fully evaporated before using the HF surgical equipment.
Ensure that no flammable liquids collect beneath the patient or in
body cavities (e.g. the vagina). Suction and/or flush body cavities before activating the device.
Wipe off all liquids before using the HF device. Ensure that no endogenous gases are present that could ignite. Ensure that all materials saturated with oxygen (e.g. cotton, gauze)
are removed far enough from the HF environment that they cannot ignite.
2.5.2. Application of the neutral electrode
Please read and comply with the notes about using the neutral electrode listed in the user manual as well as the information on the packaging of the neutral electrode.
In the monopolar HF method, the neutral electrode feeds the current introduced into the patient's body at the surgical site back to the HF device.
To prevent a rise in temperature at the current emergence point,
the following conditions must be ensured: sufficiently large contact surface between the neutral
electrode and the patient's body
high electrical conductivity between the neutral electrode
and the patient's body
Page 23
2 Safety
900-301_IFU-V2.2_11316-S0-20131023-EN Operating Manual ARC 250 / 303 23
To prevent the patient being burned by the neutral electrode, you
must comply with the following conditions: Select the application point for the neutral electrode so
that the current paths between the active and neutral electrodes are as short as possible and run longitudinally or diagonally to the patient's body (because muscles are more conductive in the direction of the fibrils).
Figure 2-1: Application point of neutral electrode
During surgery in the thoracic region, do not run the
current path transversely across the patient's body and ensure that the patient's heart is never in the path of the current.
Depending on the surgical site, apply the neutral
electrode to the nearest upper arm or thigh if possible, but never closer than 20 cm.
In the case of self-adhesive disposable electrodes,
comply with any further manufacturer specifications regarding the point of application.
Ensure that the application point is free of scar tissue,
bony protuberances, surface hair and ECG elecrodes.
Ensure that there are no implants (e.g. bone nails, bone
plates, endoprostheses) in the current path.
Ensure that no short circuits can occur at the neutral
electrode connection.
Avoid locations where fluids may collect.
Before applying the neutral electrode
Shave the area where the neutral electrode will be applied. Clean the application site, but do not use any alcohol, as it dries
out the skin and increases the transition resistance.
If the patient has poor circulation, massage or brush the application
site.
Apply the neutral electrode using the entire contact surface. Secure
reusable neutral electrodes with rubber bands or elastic ties so that they do not loosen or fall off when the patient moves. Ensure that the patient's circulation is not impaired (risk of necrosis).
Never use wet towels or electropastes.
Page 24
2 Safety
Ensure that no liquids (e.g. cleaning fluids, disinfectants, blood,
urine) get between the patient and the neutral electrode.
Do not place the neutral electrode under the patient's buttocks or
back.
Ensure that there are no ECG electrodes in the current path of the
HF device.
Example application using a disposable electrode
Remove the protective film and attach the self-adhesive disposable
electrode to the patient. Ensure that the long side of the disposable electrode faces the operation site and the electrode is fully in contact with the skin. This avoids excessive current concentration on the short side.
Using both hands, press the self-adhesive disposable electrode
firmly against the patient’s skin.
Clamp the electrode tab to the neutral electrode cable. After the operation, remove the disposable electrode carefully to
avoid skin damage.
Use of a one-piece neutral electrode
Check the one-piece neutral electrode during the surgery.
Use of a split neutral electrode
Apply the split neutral electrode correctly and without any additional
objects, as the HF device does not recognize the bridging of the section surfaces by other objects.
See chapter EASY neutral electrode monitoring (EASY monitoring), page 31, for additional information about monitoring the neutral electrode.

3. Functionality
The HF device is controlled by a microprocessor and converts the mains voltage into a high-frequency alternating current for monopolar or bipolar applications.
The "ARC Control" regulator reduces the output power to the minimum level necessary, depending on the tissue and its resistance.
Pos: 15 /679-BOWA/HF-Geräte/ARC 200/ 250/300e/3 Fu nktionsweise/M onopolare Modi @ 7\mod_130 9495624646_ 6.doc @ 52380 @ 233333
3.1. Monopolar modes
In monopolar operation, the HF device has the following operating modes:
"Cut" for cutting in low-resistance tissue  "Moderate Coag" for contact coagulation  "Forced Coag" for coagulation with light contact  "Spray Coagulation" for contactless surface coagulation
Instruments can be connected to monopolar output (socket connector 29/30).
3.1.1. "Cut" mode
In this mode a powerful HF current with a low crest factor is used for cutting in biological tissue. The maximum power is 250 W with the ARC 250, or 300 W with the ARC 303. The ARC CONTROL regulator quickly adjusts the output power to the minimum level necessary in response to variations in the tissue and changes in the cutting surface or cutting speed.
When setting the blend function between level 0 and 9, it is possible to set a variably adjustable degree of surface scabbing.
3.1.2. "Moderate Coag" mode
This mode is used in contact coagulation for stopping hemorrhagic oozing, hemostasis of larger tissue areas, and coagulation over smaller surfaces.
Page 26
3 Functionality
3.1.3. "Forced Coag" mode
If you wish to change the settings for "Forced Coag" mode, see section Menu program 3 "Forced Coag Mode", page 46.
This mode is used for contact coagulation extending over a short distance in the tissue, preferably using electrodes with fine tips or small surfaces.
Three sub-modes are available in "Forced Coag" mode:
Mode
Characteristics
Application
Non Cutting
High coagulation rate Minimal cutting tendency
Requirements for good coagulation without cutting tissue
Mixed Mode
High coagulation rate Moderate cutting effect
All standard applications (factory setting)
Cutting Mode
Good hemostasis Outstanding cutting effect
Preparatory cutting with the blue key
The simultaneous activation of two monopolar connection ports makes it possible to use two manually controlled instruments at the same time. Handles with finger switches can be connected to connection ports 29/30. The handles are activated with the "Coag" button on the handle. Both handles can be switched on or off independently of one another.
The set power applies to both connection ports. The distribution of the power depends on the tissue structure and may change during the application.
3.1.4. "Spray Coagulation" mode
This mode is used for contactless surface coagulation via arcing. This mode is used for hemostasis in parenchymal tissue or in poorly
accessible crevices and in conjunction with argon coagulation.
The simultaneous activation of two monopolar connection ports makes it possible to use two manually controlled instruments at the same time. Handles with finger switches can be connected to connection ports 29/30. The handles are activated with the "Coag" button on the handle. Both handles can be switched on or off independently of one another.
The set power applies to both connection ports. The distribution of the power depends on the tissue structure and may change during the application.

3.1.5. "GastroCut" mode
If you wish to change the settings for "GastroCut" mode, see section Menu program 3A "GastroCut-Modes", page 47.
This mode consists of a pulse sequence of cutting current and coagulation phase.
This mode is used for the removal of polyps or for making incisions in papillae. The following applies:
Blend 0 = low coagulation rate  Blend 9 = high coagulation rate
Three sub-modes are available in "GastroCut" mode:

3.2. Bipolar modes
Special instruments are necessary in order to achieve optimal results using the bipolar method (particularly with minimally invasive surgery).
Advantages of the bipolar method: The required high-frequency output is only one-fourth of the
output required for the monopolar method.
It is not necessary to apply a neutral electrode to the patient,
which eliminates the associated risks to the patient.
Instruments can be connected to the bipolar output (socket connector 31).
The AUTOSTART mode can be activated only for bipolar coagulation. In the AUTOSTART mode, the coagulation current is automatically
added after low-resistance tissue contact of the connected bipolar instruments. Thus activation using the foot switch is not necessary.
If an output operating in AUTOSTART mode is activated using the foot switch, AUTOSTART mode is deactivated and the foot switch signal is used.
This type of current can be used for bipolar cutting instruments. This type of current is suitable for the application of bipolar scissors, e.g.
BOWA BiZZER.
To prevent activation problems in AUTOSTART mode, we recommend limiting the bipolar cable length to 4.5 meters or less.
Forceps
Under moist conditions the forceps may be released accidentally, for example by contact with blood. This can cause an undesirable increase in the duration of the surgical therapy.
When the forceps are set aside with AUTOSTART enabled, inadvertent activation with associated risk of injury may occur when the forceps are wiped with a moist cloth or come in contact with metallic components, such as other instruments.

3.7. Neutral electrode monitoring
Always use the largest possible electrode when attaching a neutral electrode.
3.7.1. General information
BOWA recommends using split neutral electrodes, since only this type of electrode allows the HF device to detect detachment of the neutral electrode if this occurs.
Monitoring of the neutral electrode minimizes the risk of burns at the site where the neutral electrode is attached.
Two types of neutral electrodes can be monitored:
One-piece neutral electrodes  Split neutral electrodes.
The split neutral electrodes are shown on display 20, and the one-piece neutral electrodes are shown on display 19, see chapter Error Display in EASY monitoring, page 55.

3.7.2. EASY neutral electrode monitoring (EASY monitoring)
Children's electrodes cannot be monitored by the EASY system, because their resistance is too high due to their small surfaces.
The EASY monitoring system measures changes in resistance between the patient and the high-frequency surgery device both before and during HF activation. If required, it requests personnel to intervene via an optical and acoustic alarm. For this purpose, a split neutral electrode with corresponding contact surfaces and suitable transition resistances which is attached to the patient according to the manufacturer's instructions is required. The EASY system does not monitor partial currents in the two contact pads of the split neutral electrode.
The min. pad area of the electrode must be set to 110 cm² for the "Resection" program and the "Moderate Coagulation" mode.

Portable and mobile wireless devices, as well as their cables, should not be used within the recommended protective distance from the ARC 250 and ARC 303 as calculated using the formula appropriate to the transmission frequency.
Recommended protective working distance:
d = 0.35 × √P d = 0.35 × √P for 80 MHz to 800 GHz d = 0.7 × √P for 800 MHz to 2.5 GHz where P is the nominal transmitter output in
watts (W) specified by the transmitter manufacturer and d is the recommended protective distance in meters (m).
The field strength of stationary transmitters as determined by on-site measurementsa should be lower than the compliance levelb at all frequencies.
Interference is possible in the vicinity of devices that bear the following symbol.
Radiated HF interference as per IEC 61000-4-3
3 V/m 80 MHz to 2.5 Hz
10 V/m
Note 1
The higher frequency range applies to 80 MHz and 800 MHz.
Note 2
These guidelines may not be applicable in all cases. The propagation of electromagnetic waves is influenced by their absorption and reflection by buildings, objects and people.
a
Field strengths from stationary transmitters such as base stations for wireless telephones and land mobile radios, amateur radio, AM and FM radio broadcasting and TV broadcasting cannot be predicted theoretically with accuracy. A study of the electromagnetic phenomena at the location should be done to determine the electromagnetic environment resulting from stationary transmitters. If the measured field strength at the location where the ARC 250 and ARC 303 is used exceeds the aforementioned compliance level, the ARC 250 and ARC 303 should be monitored to verify that it is operating as intended. If unusual performance characteristics are observed, additional measures may be necessary, such as repositioning or relocation of the ARC 250 and ARC 303.
b
The field strength should be lower than 10 V/m over the frequency range of 150 kHz to 80 MHz.
