Electromagnetic environment – guidance

The Midmark Dental Light uses RF energy only for its internal functions. Therefore, its RF emissions are very low and are not likely to cause any interference in nearby electronic equipment.

The Midmark Dental Light is suitable for use in all establishments other than domestic and those directly connected to the public low-voltage power supply network that supplies buildings used for domestic purposes.

Recommended separation distances between portable and mobile RF communications equipment and the

Midmark Dental Light

The Midmark Dental Light is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the Midmark Dental Light can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communication equipment (transmitters) and the Midmark Dental Light as recommended below, according to the maximum output power of the communications equipment.

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 aff ected by absorption and refl ection from structures, objects and people.

Field strength from fi xed RF transmitters, as determined by the electromagnetic site survey, a 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 aff ected by absorption and refl ection from structures, objects and people.

a Field strengths from fi xed 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 fi xed RF transmitters, an electromagnetic site survey should be considered. If the measured fi eld strength in the location is which the Midmark Dental Light is used exceeds the applicable

RF compliance level above, the Midmark Dental 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 Midmark Ultra Chair.

b Over the frequency range 150kHz to 80MHz, fi eld strengths should be less than 3 V/m.
