2.1.2 Electromagnetic immunity
In accordance with the IEC 60601-1-2 standard, Ow-RX is suitable for
use in the electromagnetic environment described below.
The customer or user of the system must ensure that it is used in the
said environment.

Ow-RX user requires
continuous operation
during interruptions in
the mains voltage, it is
recommended to power
the Ow-RX with an
uninterrupted power
supply or batteries.
