environment.  If the user 

of the AMM240ED image 

intensifier requires con-

tinued operation during 

power mains interrup-

that the AMM240ED 

image intensifier be 

powered from an uninter-

Portable and mobile RF communications 

equipment should be used no closer to 

any part of the 

AMM240ED, including 

cables, than the recommended separation 

distance calculated from the equation 

applicable to the frequency of the 

transmitter.

800 MHz to 2.5 GHz

where 

P is the maximum oputput 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 deter-mined by an electromagnetic 

site survey 

(a), should be less than the 

compliance level in each frequency range 

(b).Interferency may occur in the vicinity 

of equipment marked with the follwing 

symbol:

NOTE 1: At 80MHz and 800MHz, 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 mo-

bile radios, amateur radio, AM and FM radio broadcast and TV broadcast, cannot be predicted theoretically with accu-

racy.  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 AMM240ED is used exceeds the applicable 

RF compliance level above, the AMM240ED should be observed to verify normal operation. If abnormal performance is 

observed, additional measures may be necessary, such as reorienting or relocating the AMM240ED.
(b) Over the frequency range 150kHz to 80MHz, field strengths should be less than [V1] V/m.
