The YE660D is intended for use in the electromagnetic environment specified
below. The customer or the user of the YE660D should assure that it is used in
such and environment.

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 YE660D is used exceeds the
applicable RF compliance level above, the YE660D should be observed to verify
normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the YE660D.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m

NOTE If necesary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting
antenna and theME EQUIPMENT or ME SYSTEM may be reduced to 1 m. The 1 m test distance is
permitted by IEC61000-4-3.
