Appendix A: EMC Information

This device is intended for use in the electromagnetic environment specified below. The user of this 
device should make sure it is used in such an environment. 

Conducted RF

IEC 61000-4-6

Radiated RF

IEC 61000-4-3

3 Vrms

  150 kHz to 80 MHz

3 V/m

  80 MHz to 2.5 GHz

3 Vrms

3 V/m

Portable and mobile RF communications equipment 

should be used no closer to any part of the device, 

including cables, than the recommended separation 

distance calculated from the equation applicable to 

the frequency of the transmitter.

d = 1.2     150 kHz to 80 MHz

d = 1.2     80 MHz to 800 MHz

d = 2.3     800 MHz to 2.5 GHz

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 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 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, 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 device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal 

operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device.

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