Manufacturer's declaration - electromagnetic immunity
The Model AMM213TD/AMM240WTD is intended for use in the electromagnetic environment specified below.
The customer or the user of AMM213TD/AMM240WTD should ensure that it is used in such an environment.
IEC 60601 Test
Immunity Test
Conducted RF 3 Vrms
IEC61000-4-6 150 KHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80MHz to 2.5 GHz
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
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, connot 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 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, field strengths should be less than [V1] V/m.

Power frequency mag-
netic fields should be
at levels characteristic
of a typical location in
a typical commercial or
hospital environment.
Mains power quaility
should be that of a typical
commercial or hospital
environment. If the
user of the AMM213TD/
AMM240WTD image
intensifier requires con-
tinued operation during
power mains interrup-
tions, it is recommended
that the AMM213TD/
AMM240WTD image in-
tensifier be powered from
an uninterruptible power
supply or a battery.
Electromagnetic environment
- guidance
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 fixed 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
