Alignment
IgniteNet strongly recommends using the ICC-SCOPE-9x50
Alignment Scope for alignment. To install, place the scope on top of
the MetroLinq™ housing and secure it with its thumb screw.
Software
For more configuration details and training, please go to
ignitenet.com/support
Note:
Do not adjust bolts A and B without first loosening 1
and 4 respectively.
Loosen coarse adjustment bolts 2 and 3 and set initial
alignment. Don’tworry, you don’t have to be too accurate
yet. After you have set the coarse alignment, tighten bolts 2
and 3.
Loosen the horizontal fine-tune adjustment bolt 4. Use fine-
tune bolt "B" to optimize the horizontal position. Re-tighten
bolt 4.
Loosen the vertical fine-tune adjustment bolt 1. Use fine-
tune bolt "A" to optimize the vertical position. Re-tighten
bolt 1.
Initial alignment should be based on optical or visual
alignment. After you achieve this, repeat steps 2 and 3 while
watching the 60 GHz signal strength LED. Optimize position
to the LED indicator.
Ensure all bolts are fully tightened, remove the alignment
scope (if installed), and enjoy Gigabit interference-free
wireless.

Safety and Regulatory Information
FCC Class B
This device complies with Part 15 of the FCC 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.
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. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter.
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 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
FCC Caution: Any changes or modifications not expressly approved by
the party responsible for compliance could void the user’s authority to
operate this equipment.
This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.
Operation within the 5.15 ~ 5.25GHz / 5.47 ~5.725GHz frequency range
is restricted to an indoor environment. The 5600-5650MHz band is
disabled by software during manufacturing and cannot be changed by
the end user. This device meets all the other requirements specified in
Part 15E, Section 15.407 of the FCC Rules.
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for
an uncontrolled environment. This equipment should be installed and
operated with minimum distance 56 cm between the radiator and your
body.
Note: The country code selection is for non-US models only and is not
available on all US models. Per FCC regulation, all Wi-Fi products
marketed in the US must be fixed to US operation channels only.
