Electromagnetic Guidance and manufacturer's declaration
Electromagnetic environment guidance
A typical commercial or hospital environment mains power
source is suitable. If the user of the Connect WS requires
continued operation during power mains interruptions, it is
recommended that the Connect WS be powered from an
uninterruptible power supply.
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical commercial or
hospital environment.
