manufacturers confirm that the combination is safe to use.
Follow the instructions in the user manual for those accessories.
• Only the following accessories may be used with the
Leica M220 F12 surgical microscopes:
• The Leica Microsystems accessories described in chapter9
this User Manual.
• Other accessories, provided that these have been expressly
approved by Leica as being technically safe in this context.
• Modifications to or service on the Leica M220 F12 surgical
microscope may be carried out only by technicians who are
explicitly authorized by Leica to do so.
• Only original Leica replacement parts may be used in servicing
the product.
• After service work or technical modifications, the device must

• If the instrument is modified or serviced by unauthorized
persons, is improperly maintained (as long as maintenance was
not carried out by us), or is handled improperly,
LeicaMicrosystems will not accept any liability.
• The effect of the surgical microscope on other instruments has
been tested as specified in EN 60601-1-2. The system passed the
emission and immunity test. Comply with the usual pre-
cautionary and safety measures relating to electromagnetic and
other forms of radiation
• The electric installation in the building must conform to the
national standard, e.g., current-operated ground leakage
protection (fault-current protection) is suggested.

Safety notes
4 Leica M220 F12 / Ref. 10 716 922 / Version 03
• Like any other instrument in the operating theater, this system
may fail. Leica Microsystem (Schweiz) AG therefore
recommends that a backup system is kept available during the
operation.
• Only the supplied power cord may be used.
• The power cord must have a protective conductor and must be
undamaged.
• The power cord must be mechanically secured with the "Power
Input" socket to prevent accidental disconnection.
• The Leica Microsystems surgical microscope may be used only
by physicians and medical assistance personnel with
appropriate qualifications who have been instructed in the use
of the instrument. Specific training is not required.
• All parts of the Leica M220 F12 shall not be serviced or
maintained while in use with a patient.
• Use of this equipment adjacent to other equipment should be
avoided because it could result in improper operation. If such
use is necessary, this equipment and the other equipment
should be observed to verify that they are operating normally.
• Use of accessories and cables other than those specified or
provided by the manufacturer of his equipment could result in
increased electromagnetic emissions or decreased
electromagnetic immunity of this equipment and result in
improper operation.
• The Leica M220 F12 surgical microscope may be used only in
closed rooms and must be placed on a solid floor.
• Portable RF communications equipment (including peripherals
such as antenna cables and external antennas) should be used
no closer than 30 cm (12 inches) to any part of the Leica M220,
including cables specified by the manufacturer. Otherwise,
degradation of the performance of this equipment could result.
Note:
The EMISSIONS characteristics of this equipment make it suitable
for use in industrial areas and hospitals (CISPR 11 class A). If it is
used in a residential environment (for which CISPR 11 class B is
normally required) this equipment might not offer adequate
protection to radio-frequency communication services. The user
might need to take mitigation measures, such as relocating or
re-orienting the equipment.
3.5 Directions for the operator of the
instrument
X Follow the instructions described here.
X Follow the instructions given by your employer regarding the
organization of work and safety at work.
X Check the illumination intensity before and during surgery.
X Don't move system without released brakes.
X Operate the system only with all equipment in its proper
position (all covers tted, doors closed).
X To avoid the risk of electric shock, this equipment must only be
connected to a supply mains with protective earth.
X All parts of the M220 shall not be serviced or maintained while
in use with a patient.
X The LED module shall not be changed while in use with a
patient.
Phototoxic damage to the retina during eye surgery
WARNING
Damage to the eyes due to prolonged exposure!
The light of the instrument may be harmful. Risk of eye
damage increases with the duration of exposure.
X During exposure to the light from this instrument, do
not exceed the hazard reference values.
If the exposure time exceeds 1 min with this instrument
at maximum output power, the hazard reference value
will be exceeded.

Safety notes
Leica M220 F12 / Ref. 10 716 922 / Version 03 5
The following table is intended to serve as a guideline and make
the surgeon aware of the potential hazard. The data have been
calculated for the worst-case scenario:
• Eye with aphakia
• Completely unmoving eye (continuous irradiation of the same
region)
• Uninterrupted light exposure, e.g. no surgical instruments in
the eye
• Pupils dilated to 7 mm
The calculations are based on the corresponding ISO standards1) 2)
and the exposure limit values recommended in them.
Light setting
Recommended maximum exposure time according to 1)
[min.]
Without filter With GG435 filter With GG475 filter
25 % 6.7 9.1 20.1
50 % 3.3 4.6 16.5
75 % 2.2 3.0 11.0
100 % 1.7 2.3 5.1
Use the protection filter 5× (10448676) to increase the
operation duration by a factor of 5 compared to the
standard configuration without a filter.
Sources:
1) DIN EN ISO 15004-2:2007 Ophthalmic instruments –
Fundamental requirements and test methods – Part 2: Light
hazard protection.
2) ISO 10936-2:2010 Optics and photonics – Operation
microscopes/Part 2: Light hazard from operation microscopes
used in ocular surgery.
Protect the patient with the following safeguards:
• Short illumination times
• Low brightness setting
• Use of protective filters
• Switching off the illumination during breaks in the operation
It is recommended to adjust the brightness to the minimum
necessary for the surgery. Infants, patients with aphakia (whose
eyelens has not been replaced by an artificial lens with a UV
protection screen), small children and persons with diseases of the
eye are at greater risk. The risk is also increased if the person being
treated or operated on has, within the last 24 hours, already been
exposed to illumination from the same or any other
ophthalmological instrument that uses a bright visible light source.
This applies especially to patients that have been examined via
retinal photography.
The decision about which light intensity to use for an application
must be made on a case-by-case basis. In any event, the surgeon
must evaluate the risks and benefits of the used light intensity.
Despite all efforts to minimize the risk of retinal injury by surgical
microscopes, damage may still occur. Photochemical retinal
damage is a possible complication of the necessity to use bright
light to make eye structures visible during difficult
ophthalmological processes.
Stability (floor stands only)
When moved in the operating room, the swing arm must be folded
up and locked and the brakes must be applied, otherwise the swing
arm could drift out of control and the stand could topple.
Hazards due to movable parts
This section describes uses that, inadvertently, could lead to
hazardous situations.
• Add accessories and balance the stand before the operation,
and never over the field of operation.
• Do not put your fingers between the microscope and the
focusing drive; They could get crushed.
Floor stand
• Always push the instrument to move it; never pull it. Feet in
lightweight shoes could become trapped beneath the casing of
the base.
• The footbrakes must remain engaged throughout the
operation.
Electrical connections
The control unit may be opened only by a Leica-approved service
technician.
Accessories
Only the following accessories may be used with the Leica
Leica M220 F12 surgical microscopes:
• The Leica Microsystems accessories described in this User
Manual.
• Other accessories, provided that these have been expressly
approved by Leica as being technically safe in this context.
