continuous functionality
even if there are
interruptions in the power
supply, powering the
emField Pro using an
uninterrupted power supply
or battery is recommended.

Hz) in accordance with
IEC 61000-4-8 3 A/m 3 A/m Magnetic fields at the mains
frequency should
correspond with the typical
values found in business or
hospital environments.
