Electromagnetic compatibility

Guidance and manufacturer’s declaration – electromagnetic immunity
This device is intended for use in the electromagnetic environment specified below. The customer or 

user of this device should assure that it is used in such an environment.
Immunity test IEC 60601 

Conducted RF 

according to 

IEC 61000-4-6

3 V

eff

150 kHz to 

80 MHz

3 V

Portable and mobile RF communications equipment 

should be used no closer to any part of the Olympus 

CELON ELITE ESG-200, including cables, than the 

recommended separation distance calculated from the 

equation applicable to the frequency of the transmitter.

d = 1.2 √ P

d = 1.2 √ P 80 MHz to 800 MHz

d = 2.3 √ P 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:

Radiated RF

IEC 61000-4-3

3 V/m

80 MHz to 

2.5 GHz

3 V/m

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 Olympus CELON 

ELITE ESG-200 is used exceeds the applicable RF compliance level above, the Olympus 

CELON ELITE ESG-200 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, field strengths should be less than 3 V/m.

This device is intended for use in an electromagnetic environment in which radiated RF disturbances 

are controlled. The customer or user of this device can help prevent electromagnetic interference 

by maintaining a minimum distance between portable and mobile RF communications equipment 

(transmitters) and this device as recommended below, according to the maximum output power of the 

communications equipment.
