Guidelines and MANUFACTURER declaration – ELECTROMAGNETIC STABILITY
The BaehrTec A2000 model is intended for operation in the ELECTROMAGNETIC ENVIRONMENT specified below. The
customer or the user
N15)
of the BaehrTec A2000 model should ensure that it is used in such an environment.

In accordance with an investigation
on site,
a
the field strengths of fixed
transmitters is lower than the
COMPLIANCE LEVEL
b
at all
frequencies.
Interference is possible in the
vicinity of devices marked with the
following symbols.
NOTE 1 At 80 MHz and 800 MHz, the higher value applies.
NOTE 2 These guidelines may not apply in all situations. The distribution of electromagnetic waves is affected by
absorption and reflections from buildings, objects and people.
a
Field strengths of fixed transmitters, such as base stations for mobile phones and Land Mobile Services,
amateur stations, AM and FM radio and television channels, cannot be predicted theoretically with accuracy.
In order to
ascertain the ELECTROMAGNETIC ENVIRONMENT as a result of stationary HF transmitters, an investigation of the
location is recommended. If the measured field strength at the location of the BaehrTec A2000 model exceeds the
above COMPLIANCE LEVEL, the BaehrTec A2000 model must be monitored terms of its normal operation
at every application location. If any unusual features are observed, it may be necessary
to take additional measures, such as realigning or relocating the BaehrTec A2000 model.
b
Over the frequency range from 150 kHz to 80 MHz the field strength is less than 3 V/m.
