Electromagnetic Immunity - Conducted and radiated RF
The EcoStar Info or EcoStar Auto device is designed for use in the electromagnetic environment specified
below. The customer or the user of the device should ensure that it is used in such an environment.

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).

Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the highest 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 wireless (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcasts and TV broadcasts cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be consulted. If the measured field strength in the location in which the EcoStar Info or EcoStar Auto device is to
be used exceeds the applicable RF compliance level shown above, the device should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the EcoStar Info or EcoStar Auto device.
(b)
Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3 V / m.
