Microlife BP3GT1-6B, Instruction Manual

Guidance and manufacturer’s declaration-electromagnetic immunity 

The BP3GT1-6B is intended for use in the electromagnetic environment specified below. 

The customer or the user of the BP3GT1-6B should assure that is used in such and environment.

Portable and mobile RF communications 

equipment should be used no closer to any part 

of the BP3GT1-6B including cables, than the 

recommended separation distance calculated 

from the equation applicable to the frequency of 

the transmitter. 

Recommended separation distance:

Where

 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 metres 
(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 symbol: 

NOTE1      At 80 MHz and 800 MHz, the higher frequency range applies. 

NOTE2      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 BP3GT1-6B is used exceeds the applicable RF 
compliance level above, the BP3GT1-6B should be observed to verify normal operation. If abnormal performance is 
observed, additional measures may be necessary, such as re-orienting or relocating the BP3GT1-6B. 

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