Guidance and Manufacture's Declaration for Electromagnetic Immunity for non-life support systems
The curing light is intended for use in the electromagnetic environment specified below. The customer or user should ensure that it is used in such an environment.
IMMUNITY test IEC 60601 test level
Conduction RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
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 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 curing light is used exceeds the applicable RF compliance level above, the curing light should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the curing light.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Guidance and Manufacture's Declaration for recommended separation distances between portable and mobile RF communications equipment and the curing light
The curing light is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The user of the curing light can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the curing light as recommended below, according
to the maximum output power of the communications equipment.

The curing light has been tested according to IEC 60601-1-2:2014 and passed under radiated field strengths of 10 V/m between 80-MHz to 2.5 GHz. The value of 3Vrms corresponds
to V1 and the value 10 V/m corresponds to E1 in the formulas above.
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.

Compliance level Electromagnetic environment guidance
3 Vrms Portable and mobile RF communications equipment should be used no closer to any part of the
curing light, including cables, than the recommended separation distance calculated from the
150 kHz to 80 MHz
equation applicable to the frequency of the transmitter.
3 V/m
Recommended separation distance
80 MHz to 2.5 GHz
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 meters (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site surveya,
should be less than the compliance level in each frequency rangeb.
Interference may occur in the vicinity of equipment marked with the following symbol:
