Guidance and manufacturer's declaration – electromagnetic immunity
The MODEL ABP801 is intended for use in the electromagnetic environment specified below. The customer or the
user of the MODEL ABP801 should assure that it is used in such an environment.

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 MODEL ABP801 is used exceeds the

where 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).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey, should
be less than the compliance level in each frequency
