We are required by regulations to provide the following warnings:
WARNING:
Use
of SurfLink Remote Microphone or SurfLink Mini
Mobile
Adapter
directly next to other electronic equipment should be
avoided
because
it could result in improper performance. If
such
use
is
necessary,
note
as
to whether your hearing aids and the other equipment
are operating normally.
WARNING:
Use
of
accessories,
components or replacement parts other
than those provided by the
manufacturer
of SurfLink Remote Microphone
or SurfLink Mini Mobile
Adapter
could result in increased
electromagnetic
emissions
and
decreased
electromagnetic immunity and
could result in degradation of performance.
WARNING: If Portable
Radio Frequency communications
equipment is
used closer than 30 cm
(12
inches)
from SurfLink Remote Microphone or
SurfLink Mini Mobile Adapter, degradation of the performance of SurfLink
Remote Microphone or SurfLink Mini Mobile Adapter could result. If this
occurs,
move away from the
communications
equipment.
