FCC Warning
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. 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.
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.
FCC Caution
To assure continued compliance, any changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate this equipment.
FCC Radiation Exposure Statement
To comply with FCC RF exposure requirements in section 1.1307, a minimum separation distance of 3.9 feet is
required between the antenna and all occupational persons, and a minimum separation distance of 8.7 feet is
required between the antenna and all public persons.
Antenna Installation
WARNING: It is installer’s responsibility to ensure that when using the authorized antennas in the United States
(or where FCC rules apply), only those antennas certified with the product are used. The use of any antenna
other than those certified with the product is expressly forbidden in accordance to FCC rules CFR47 part 15.204.
The installer should configure the output power level of antennas, according to country regulations and per
antenna type. Professional installation is required of equipment with connectors to ensure compliance with
health and safety issues.

Antenna Compliance
The LigoPTP 3-N radio module is compliant with any antenna of lesser or equal gain as specified in the chart
below given channel bandwidth and radio conducted power. A higher gain antenna may be used if radio
conducted power is lowered. For every 1dBm that the radio’s conducted power is lowered, an increase of 1dB
may be added to the allowed antenna gain assuming the total EIRP does not exceed the Limit in the following
table.
