Manufacturer's Declaration - Electromagnetic Immunit
The Model AMM215WTTP is intended for use in the electromagnetic environment specified below. The customer
or the user of AMM215WTTP should ensure that it is used in such an environment.
Immunity Test IEC 60601 Test Level
Conducted RF 3 Vrms
IEC61000-4-6 150 KHz to 80 MHz
Radiated RF 3 Vrms
IEC 61000-4-3 800 MHz 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 AMM215WTTP is used
exceeds the applicable RF compliance level above, the AMM215WTTP should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the AMM215WTTP.
(b) Over the frequency range 150kHz to 80MHz, field strengths should be less than [V1] V/m.

Electromagnetic Environment - Guidance
Portable and mobile RF communications
equipment should be used no closer toany
part of the AMM215WTTP, includingcables,
than the recommended separationdistance
calculated from the equationapplicable to the
frequency of thetransmitter.
Recommended Separation Distance0.15 MHz
to 80 MHz
80 MHz to 800 MHz
800 Mhz to 2.5GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and is the recommended separation
distance in meters (m). Field strengths from
fixed RF transmitters,as determined by an
electromagneticsite 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 following
symbol:

Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial orhospital
environment.
Mains power quailityshould
be that of a typicalcommercial
or hospitalenvironment. If the
user of the AMM215WTTP
image intensifier
requirescontinued operation
during power mains
interruptions, it is commended
that the AMM215WTTP image
intensifier bepowered from an
uninterruptible power supply
or a battery.
