Guidance and Manufacturer’s Declaration for Electromagnetic Immunity

The CR-2 is intended for use in the electromagnetic environment specified below.

The customer or the user of the CR-2 should assure that it is used in such an environment.

Field strengths from fixed RF transmitters,

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.

aField 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 CR-2 is used exceeds the applicable RF compliance level above, the CR-2 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the CR-2.

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