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 ABP802 is used exceeds the applicable RF compliance
level above, the MODEL ABP802 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating
the MODEL ABP802.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
portable and mobile RF communications equipment and the MODEL ABP802
The MODEL ABP802 is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the MODEL ABP802 can help
prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the MODEL ABP802 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 meters (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 transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
