RF emission - CISPR 11
Group 1
The Ameda Mya uses RF energy only for its internal
function. Therefore, its RF emissions are very low
and are not likely to cause any interference in near-
by electronic equipment
RF emission - CISPR 11
Group B
The Ameda Mya is suitable for use in all
establishments, including domestic establishments
and those directly connected to the public low-
voltage power supply network that supplies
buildings used for domestic purposes, provided the
following warning is heeded:
Warning: This equipment/system may cause radio
or may disrupt the operation of nearby equipment.
It may be necessary to take mitigation measures,
such as re-orienting or relocating the Ameda Mya or
shielding the location.

of the Ameda Mya requires continued operation
during power as interruptions, it is recommended
that the Ameda Mya be powered from an uninter-
ruptible power supply or battery.
