Safety Guidelines
According to SAR regulation EN 62479:2010 the S42is not intended to be used
in close proximity to the human body. Please refer to above-mentioned regulation for
more specific information.
In respect to the safety regulation EN60950-1: 2006 + A11: 2009 + A1: 2010 + AC: 2011 all
conductive parts of the S42are to be classified as SELV circuitry. OEM’s
implementing the S42in their products should follow the isolation rules given
in regulation EN 60950-1: 2006.
The PCB material of the S42 is classified UL-94V0.

Cleaning
In general, cleaning the modules mounted on the host board is strongly discouraged.
Residues between module and host board cannot be easily removed with any cleaning
method.
•
Cleaning with water or any organic solvent can lead to capillary effects where the
cleaning solvent is absorbed into the gap between the module and the host board.
The combination of soldering flux residues and encapsulated solvent could lead to
short circuits between conductive parts. The solvent could also damage any labels.
•
Ultrasonic cleaning could damage the module permanently. Especially for crystal
oscillators the risk of damaging is very high.
