Precautions on FCC
The BL-N90 Series conforms to the following FCC regulations.
• Applicable standard FCC Part 15 Subpart B, Class B Digital Device
FCC Part 15 Subpart C
• FCC ID RF40823A (BL-N90)
RF40823B (BL-N9R/N9UB/N9V)
FCC WARNING
Changes or modifications not expressly apprvoed by the party responsible for
compliance could void the user's authority to operate the equipment.This device complies
with Part 15 of the FCC Rules and RSS-Gen of the IC Rules. Operation is subject to the
following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
NOTICE
•
The BL-N90 and the BL-N9R/N9UB/N9V have 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 BL-N90 and the BL-N9R/N9UB/N9V generate, use 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 the BL-N90 and
the BL-N9R/N9UB/N9V do 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.
The BL-N9R/N9UB/N9V complies with FCC radiation exposure limits set forth for
uncontrolled equipment and meets the FCC radio frequency (RF) Exposure Guidelines in
Supplement C to OET65. The BL-N9R/N9UB/N9V has very low levels of RF energy that it
deemed to comply without maximum permissive exposure evaluation (MPE). But it is
desirable that it should be installed and operated with at least 20cm and more between
the radiator and person's body (excluding extremities: hands, wrists, feet and legs).
The BL-N90 complies with FCC radiation exposure limits set forth for uncontrolled
equipment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement
C to OET65. The BL-N90 has very low levels of RF energy that it is deemed to comply
without testing of specific absorption ratio (SAR).
