NOTE: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. 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:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and the receiver.
- Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Safety
This equipment must be powered by a supply which is suitably insulated
from the mains. The supply should be classed as SELV under the terms
of EN60950.
The power supply must be connected to safety earth. A mains isolation
switch should be provided by the installer. Any third party equipment
connected must also be suitably insulated from the mains supply.
Any fuses which are replaced must be of the recommended rating and
type.
Wiring connected by the installer must be adequate. The use of
inadequate wiring may present a fire hazard.
Except where specified the equipment is not suitable for outside use.
Except where specified this equipment is not for use in safety critical
applications.
