Mains power quality should be that of a typical com-
mercial or hospital environment. If the user of the
MADSEN Alpha OAE+ requires continued operation dur-
ing power mains interruptions, it is recommended that
the MADSEN Alpha OAE+ be powered from an unin-
terruptible power supply or a battery.

Separation distance between any electronic parts of
MADSEN Alpha OAE+ and any RF wireless com-
munication equipment must be more than 30 cm (11.8
inches).
Note : These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
