Radio interference

the user may be required to take appropriate measures. VCCI-A
Aluminum electrolytic capacitors 
The aluminum electrolytic capacitors used in the product's printed circuit board 
assemblies and in the mouse and keyboard are limited-life components. Use of 
these components beyond their operating life may result in electrolyte leakage 
or depletion, potentially causing emission of foul odor or smoke.
As a guideline, in a normal office environment (25°C) operating life is not 
expected to be reached within the maintenance support period (5 years). 
However, operating life may be reached more quickly if, for example, the 
product is used in a hot environment. The customer shall bear the cost of 
replacing replaceable components which have exceeded their operating life. 
Note that these are only guidelines, and do not constitute a guarantee of 
trouble-free operation during the maintenance support period.

and/or industrial areas as a server.

of view to avoid incommoding reflections (applies only to TX server systems).
The device has not been designed or manufactured for uses which demand an 
extremely high level of safety and carry a direct and serious risk of life or body 
if such safety cannot be assured.
