ABPM with custo screen 300 and custo diagnostic | GEB 0154 – DK 1055 | Version 002 – 05.06.2013 | custo med GmbH
Manufacturer’s Declaration – electromagnetic immunity
The custo screen 300 ABPM recorder is designed for operation in the electromagnetic environment
stated below. The customer or user of the custo screen 300 should make sure that it is used in such an
environment.
COMMENT 1:
With 80 MHz and 800 MHz the higher frequency range is valid.
COMMENT 2:
These guidelines may not apply in every case. The propagation of electromagnetic variables is influenced by
absorptions and reflections of buildings, objects and people.
a)
The field strength of stationary transmitters, such as e.g. base stations of mobile phones and mobile
transmitting stations, amateur radio stations, AM and FM broadcasting as well as television networks
cannot be exactly predetermined theoretically. In order to determine the electromagnetic environment
regarding the stationary transmitters, a study of the location should be considered. If the measured field
strength exceeds the above-mentioned compliance levels at the location where the device is used, the
device should be watched in order to prove the intended functions. If unusual performance features
are observed, it may be necessary to take additional measures, for example reorienting or relocating the
device.

Electromagnetic Environment - Guidelines
Portable and mobile radio sets should not be used
at a closer distance to the device including the leads
than the recommended protective distance which is
determined according to the equation of transmitting
frequency.
Recommended protective distance:
d = (3.5/U1) √P
d = (3.5/E

) √P
80 MHz to 800 MHz
d = (7/E
1
) √P
800 MHz to 2.5 GHz
with P as the nominal power of the transmitter in watt
(W) according to the indications of the transmitter
manufacturer and d as the recommended protective
distance in meters (m).
According to an examination on-site
a)
the field
strength of stationary radio transmitters should be
inferior to the compliance level with regard to all
frequencies.
In the vicinity of devices carrying the following sym-
bol, interferences are possible:
