Olsen DENTAL LINE Manual Del Usuario página 26

The Olsen's Dental Units are intended for use in the electromagnetic environment specified below. The customer or the user of the
Olsen's Dental Units should assure that it is used in such an environment.
Immunity test
Conducted RF 3 V
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.
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 measure
a
filed strength in the location in which the Olsen's dental units are used exceeds the applicable RF COMPLIANCE LEVEL above, the
Olsen's Dental Units should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the Olsen's Dental Units.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the Olsen's dental units
The Olsen's Dental Units are intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the Olsen's Dental Units can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the Olsen's Dental Units 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 affected by absorption and reflection from
structures, objects, and people.
