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 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.
Electric fields
Caution:
In accordance with Part 15 of the FCC Rules & Regulations, "... changes or
modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment."
Should this product be used in an electromagnetic field that is amplitude modulated by
an audio frequency signal (20Hz to 20kHz), the signal to noise ratio may be degraded.
Degradation of up to 60dB at a frequency corresponding to the modulation signal may
be experienced under extreme conditions (3V/m, 90% modulation).
Operation
To avoid electrical shock, never operate the equipment with the covers removed.
Safety equipment
Never remove, for example, covers, housings or any other safety guards. Do not
operate the equipment or any of its parts if safety guards are ineffective or their
effectiveness has been reduced.
Optional equipment
Unless advised otherwise, optional equipment must only be installed by service
personnel and in accordance with the appropriate assembly and usage regulations.
Special accessories
To comply with part 15 of the FCC Rules, any special accessories (that is, items that
