Beurer TL80 608.10 Data Sheet

51

The model TL80 is intended for use in the electromagnetic environment specified below. The customer or 

the user should assure that it is used in such an environment.

Conducted RF 

lEC 61000-4-6 

Radiated RF lEC 

61000-4-3 

3 Vrms

150 kHz to 80 MHz

3 V/m

80 MHz to 2.5 GHz

3V

3 V/m

Portable and mobile RF communications 

equipment should be used no closer to any 

part of the model TL80, including cables, 

than the recommended separation distance 

calculated from the equation applicable to 

the frequency of the transmitter.

3V

d=1.2×P

1/2

 80 MHz to 800 MHz

d=2.3×P

1/2

 800 MHz to 2.5 GHz

where P is the maximum output power 

rating of the transmitter In watts (W) accor-

ding 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 

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 sym-

bol:  

symbol:

 

NoTE i At 80 MHz end 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 model TL80 is used exceeds the applicable RF compliance level above, the model 

TL80 should be observed to verify normal operation. If abnormal performance is observed, additional 

measures may be necessary, such as reorienting or relocating the model TL80.

b

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