is the a.c. mains voltage prior to application of the test level
Note 1: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) 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, an electromagnetic site survey should be considered. If the measured field strength
in the location in which the Keratron
™
Piccolo is used exceeds the applicable RF compliance
level above, the Keratron
™
Piccolo should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or
relocating the Keratron
™
Piccolo unit.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

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

For transmitters rates at maximum output power not listed above, the
recommended separation distance 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:
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.
