However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment to an outlet on a circuit different from that

To ensure continued compliance to EN 60601-1-2 and FCC part 15,
use only cables supplied by DynaVox Systems LLC. In addition,
only ferrite-shielded cables should be used for connecting
peripherals to any DynaVox Systems device to reduce the
possibility of interference with radio communications services.
Using ferrite-shielded cables ensures that you maintain the
appropriate electromagnetic compatibility (EMC) classification for
the intended environment. DynaVox Systems has supplied you
with one ferrite washer and instructions for attaching it to the
cable you are using.
