NOTE 1: At 80 MHz and 800 MHz, 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.
a: Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast, and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the device is used exceeds
the applicable RF compliance level above, the device should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the device.
b: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
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 metres (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.
The subject device 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.
The product 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 the interference will not occur in a particular installation. If the
product does cause harmful interference to radio or television reception, which can be determined
by turning the product on or off, the user is encouraged to try to correct the interference by one or
more of the following measures:
a) Reorient or relocate the receiving antenna;
b) Increase the separation between the product and the receiver;
c) Consult the dealer or an experienced radio / TV technician for help;
d) Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Changes or modifications to this product not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
