24 Safety and Handling
FCC compliance information
This device complies with Part 15 of the FCC`s Rules. Operation is subject to the following
two Conditions:
1
This device may not cause harmful interference, and
2
This device must accept ant interference received, including interference that may
cause undesirable operation.
This device complies with part 15 of the FCC Rules. Operation is subject to the condition
that this device does not cause harmful interference.
The antenna must be installed such that 20 cm is maintained between the antenna and
users, and the transmitter module may not be co-located with any other transmitter or
antenna.
End users cannot modify this transmitter device. Any Unauthorized modification could
void the user’s authority to operate this device.
Part 15.105 (B)
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 rea-
sonable 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 communica-
tions, However, there is no guarantee that interference will not occur in a particular instal-
lation. 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 re-
ceiver is connected.
•
Consult the dealer or an experienced radio/TV technician for help.
Modifications not expressly approved by the manufacturer could void the user’s authority
to operated the equipment under FCC rules.
FCC 15.407 (g) states
Manufacturers of U-NII devices are responsible for ensuring frequency stability such that
an emission is maintained within the band of operation under all conditions of normal
operation as specified in the users manual.
Since this is an Indoor Only device (required for this band) you do not need to worry about
the extreme frequency Stability over wide temperatures, but you can show that the fre-
quency Generation portion of this device (from the schematic) has its own stated stability
that would never allow the device to generate emissions or part of the spectrum outside
of the authorized band (can be determined by looking at the Occupied BW plots to see
how much margin to the band edge is available).
If the devices in the future use the other higher frequency UNII bands, and the devices
