AA222 Instructions for Use – US Page 85
The AA222 is intended for use in the electromagnetic environment specified below. The customer or the user of the AA222 should
assure that it is used in such an environment.

requires continued operation during
power mains interruptions, it is
recommended that the AA222 be
powered from an uninterruptable power
supply or its battery.

Portable and mobile RF communications
equipment should be used no closer to
any parts of the AA222, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
80 MHz to 800 MHz
800 MHz to 2,5 GHz
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, (a) should be less than the
compliance level in each frequency range
(b)
Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE1 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)
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 AA222 is used exceeds the applicable RF compliance level above, the AA222 should be observed to verify normal
operation, If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the AA222.
