Recommended separation distances between portable and mobile RF communications equipment and the device.
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the device can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the device as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m)
can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power
rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.

USA-FEDERAL COMMUNICATIONS COMMISSION (FCC)
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part
15 of 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. If not installed and
used in accordance with the instructions, it may cause harmful interference to radio communications. However,
there is no ensured specification 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
tuning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the distance between the equipment and the receiver.
• Connect the equipment to outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Any changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
