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 Fixed 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 access the electromagnetic environment due to fixed RF transmitters, and electromagnetic site survey
should be considered. If the measured field strength in the location in which the Product is used exceeds the applicable
RF compliance level above, the Product should b observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Product.
b over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

The Product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the Product can help prevent electromagnet interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the Product as recommended
below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres
(m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output
power rating of the transmitter in watts (W) according to the higher frequency range applies.

recommended separation distance in metres (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.
