environment – guidelines

The TRIOS system 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 TRIOS system is intended for use

in dental clinical settings, including domestic

establishments and those directly connected

to the public low-voltage power supply

network that supplies buildings used

for domestic purposes

Electromagnetic environment – guidelines

Portable and mobile RF communications equipment should be used no closer to any

part of the TRIOS system, including cables, than the recommended separation distance

calculated from the equation applicable to the frequency of transmitter.

Recommended separation distance

d = 1,2 √P

d = 1,2 √P 80 MHz to 800 MHz

d = 2,3 √P 800 MHz to 2,7 GHz

where P is the maximum output power rating of the transmitter in watts (W) according

to the transmitter manufacture and d is the recommended separation distance in meter

(m), V1 is the conducted RF compliance level, and E1 is the RF radiated compliance level.

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,

(note a, b and c) should be less than the compliance level in each frequency range.

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, object and people.

Note 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 transmitter, an electromagnetic site survey

should be considered. If abnormal performance of the TRIOS system is observed, additional

measures may be necessary, such as re-orienting or relocating the TRIOS system.

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

Note c: The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz

are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and

40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz and 80 MHz are

1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz

to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to 21,4 MHz,

24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0 MHz.

4.18 Distances Between System and Other Equipment

The TRIOS system is intended for use in an electromagnetic environment in which

radiated RF disturbances are controlled. The customer or the user of the TRIOS system

can help prevent electromagnetic interference by maintaining a minimum distance

between portable or mobile RF communications equipment (transmitters) and the

TRIOS system as recommended below, according to the maximum output power of the

communication equipment.
