MANUFACTURER’S DECLARATION – ELECTROMAGNETIC EMISSIONS
Optomed Aurora maintains basic safety and performance when used in the electromagnetic environment
specified below. The customer or the user of the device should ensure that it is used in such an environment.
Emission test Compliance level Electromagnetic environment – guidance
RF emissions
CISPR 11
| Important information
Group 1 Optomed Aurora uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely
to cause any interference in nearby electronic equipment.
RF emissions

Class B
Optomed Aurora is suitable for use in all establishments,
including domestic establishments and those directly
connected to the public low-voltage power supply network
that supplies buildings used for domestic purposes.

Complies
A) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in
the location in which the Optomed Aurora is used exceeds the applicable RF compliance level above,
Optomed Aurora should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the Optomed Aurora.
B) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
NOTE 1 UT is the AC mains voltage prior to application of the test level
NOTE 2 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 3 The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz are
6.765–6.795 MHz; 13.553–13.567 MHz; 26.957–27.283 MHz and 40.66–40.70 MHz.
NOTE 4 These guidelines may not apply in all situations. Electromagnetic propagation is aected
by absorption and reflection from structures, objects and people.
