age intensifier requires
continued operation dur-
ing power mains interrup-

that the AMM213TD2
image intensifier be
powered from an uninter-
ruptible power supply or
a battery.
Note: Ut
is the A.C. mains voltage prior to application of the test level.
The Model AMM213TD2 is intended for use in the electromagnetic environment specified below.
The customer or the user of AMM213TD2 should ensure that it is used in such an environment.

Field strengths from fixed RF transmitters,

, 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
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 AMM213TD2 is used exceeds the applicable RF
compliance level above, the AMM213TD2 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the AMM213TD2.
(b) Over the frequency range 150kHz to 80MHz, field strengths should be less than [V1] V/m.
