Measures to Prevent Electromagnetic
Interferences
The user can help avoid electromagnetic disturbances by keeping the minimum
distance between portable and mobile HF telecommunication devices (transmitters)
and the MS-12 blue/MS-12 USB Recorder. The distance depends on the output
performance of the communication device, as indicated below.
HF source
Wireless communication devices
Band 13/17
 Portable HF telecommunications equipment must not be used within 0.3 metres
of the MS-12 blue/MS-12 USB recorders including the wiring.
 Do not operate the MS-12 blue/MS-12 USB near electrical / electronic devices
and keep sufficient distance to all electrical devices.
For permanently installed HF telecommunications equipment (for example, radio and
TV transmitters), the minimum distance to the transmitter can be calculated using the
following formula: d
d = recommended minimum distance in metres
P = radiated power in watts
(Formula based on the maximum immunity level of 10 V/m in the frequency range
from 80 MHz to 3000 MHz).
For more information on operation in an electromagnetic environment according to
IEC/EN 60601-1-2, please consult the MS-12 service manual.
