Mains power quaility
should be that of a typical
commercial or hospital
environment. If the
user of the AMM213TD/
AMM240WTD image
intensier requires con-
tinued operation during
power mains interrup-
tions, it is recommended
that the AMM213TD/
AMM240WTD image in-
tensier be powered from
an uninterruptible power
supply or a battery.
Note: Ut is the A.C. mains voltage prior to application of the test level.
The Model AMM213TD/AMM240WTD is intended for use in the electromagnetic environment specied below.
The customer or the user of AMM213TD/AMM240WTD should ensure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the AMM213TD/ AMM240WTD,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.
Recommended Separation Distance
0.15 MHz to 80 MHz
80 MHz to 800 MHz
800 MHz to 2.5 GHz
where P is the maximum oputput 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 xed RF transmitters,
as deter-mined by an electromagnetic
site survey (a), should be less than the
compliance level in each frequency range
(b).Interferency may occur in the vicinity
of equipment marked with the follwing
symbol:
NOTE 1: At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reection from structures, objects, and people.
(a) Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast, connot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to xed RF transmitters, an electromagnetic site survey should be
considered. If the measured eld strength in the location in which the AMM213TD/AMM240WTD is used exceeds the
applicable RF compliance level above, the AMM213TD/AMM240WTD should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the AM-
M213TD/AMM240WTD.
(b) Over the frequency range 150kHz to 80MHz, eld strengths should be less than [V1] V/m.
