Remarks on electromagnetic tolerability
There are currently no indications that electromagnetic interactions with other devices can occur when this device is used correctly.
However, interference cannot be completely excluded under the strong influence of unfavourable field strengths, e.g. when operating a cell telephone and from radiological instruments.

Warning:
The use of other accessories may result in increased electromagnetic emissions or reduced electromagnetic immunity of the device and may lead
to incorrect operation.

Attention:
Medical electrical equipment is subject to special precautions regarding electromagnetic compatibility (EMC).
Portable and mobile radio frequency communication devices can affect medical electrical equipment. The ME device is for operation in an electromagnetic environment for  home health care and intended for professional facilities such as industrial areas and hospitals.
The user of the device should ensure that it is operated within such an environment.
Warning:
The ME device may not be stacked, arranged or used directly next to or with other devices. When operation is required to be close to or stacked with other devices, the ME  device and the other ME devices must be observed in order to ensure proper operation within this arrangement. This ME device is intended for use by medical professionals  only. This device may cause radio interference or interfere with the operation of nearby devices.
It may become necessary to take appropriate corrective measures, such as redirecting or rearranging the ME device or shield.
The rated ME device does not exhibit any basic performance features in the sense of EN60601-1, which would present an unacceptable risk to patients, operators or third  parties should the power supply fail or malfunction.
Warning: Portable RF communications equipment (radios) including accessories, such as antenna cables and external antennas, should not be used in closer proximity than 30 cm (12 inches] to parts and cables of the headlights specified by the manufacturer. Failure to comply may result in a reduction in the device’s performance features.

Conducted RF
IEC 61000-4-6| Not applicable| Not applicable| Portable and mobile RF communications equipment should be used no closer to any part of the ri-focus and clar N, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance

d= 2.3VP 800 MHz to 2.7 GHz
Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the
| | | recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey; should be less than the compliance level in each frequency range.b
Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,
objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and landmobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoreticallywith accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic sitesurvey should be considered. If the measured field strength in the location in which the Headlamps ri-focus and Forehead mirror Clar N is used exceeds the applicable RF compliance level above, the Headlamps ri-focus and Forehead mirror Clar N should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Headlamps ri-focus and Forehead mirror Clar N.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Theri-focus and clar N is intended for use in an electromagnetic environment in which radiated RF disturbances are|
controlled. The customer or the user of the ri-focus and clar N can help prevent electromagnetic interference by|
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and|
the ri-focus, clar N as recommended below, according to the maximum output power of the communications equipment.|
Rated maximum output| Separation distance according to frequency of transmitter|
