Radio frequency interference
Class B device
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 cannot be readily
obtained from multiple retail outlets) supplied with this equipment must be used with this equipment; do not
use any alternatives as they may not fulfil the RF requirement.
