Guidance and manufacturer’s declaration - electromagnetic immunity
The ENDO-MATE DT2 is intended for use in the electromagnetic environment specified below� The customer or the
user of the ENDO-MATE DT2 should assure that it is used in such an environment�

Field strengths from fixed RF transmitters
as determined by an electromagnetic site
survey, should be less than the
compliance level in each frequency
range�
Interference may occur in the vicinity of
equipment marked with the following
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
mobiles 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 ENDO-MATE DT2 is
used exceeds the applicable RF compliance level above, the ENDO-MATE DT2 should be observed to verity
normal operation� If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the ENDO-MATE DT2�
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m�
