This equipment has been tested and found to comply with the limits for an intentional radiator, pursuant
to Part 15, Subpart C of the FCC Rules. This equipment generates, uses, and can radiate radio frequency
energy. If not installed and used in accordance with the instructions, it may cause interference to radio
communications.
The limits are designed to provide reasonable protection against such interference in a residential
situation. However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause interference to radio or television reception, which can be determined by
turning the equipment on and off, the user is encouraged to try to correct the interference by one or more
of the following measures:
• Reorient or relocate the receiving antenna of the affected radio or television.
• Increase the separation between the equipment and the affected receiver.
• Connect the equipment and the affected receiver to power outlets on separate circuits.
• Consult the dealer or an experienced radio/TV technician for help.
W A R N I N G
Changes or modifications not expressly approved by ADTRAN could void the user’s authority to
operate the equipment.
SHIELDED CABLES
A shielded-type power cord is required in order to meet FCC emission limits and also to prevent
interference with nearby radio and television reception when using the AC voltage adapter. It is essential
that only the ADTRAN-provided power cord be used.
FCC OUTPUT POWER RESTRICTIONS
The FCC does not require licensing to implement this device. However, the FCC has established
restrictions regarding maximum output power and the adjustments required when employing directional
gain antennae. (Refer to “Setting the Transmitter Power” in Section 2 of this manual). These restrictions
are detailed in FCC Part 15.247 (b)(1), (b)(3)(i), and (3)(iii). It is the responsibility of the individuals
designing and implementing the radio system to assure compliance with these and any other pertinent
FCC Rules and Regulations. This device must be professionally installed.
EXPOSURE TO RADIO FREQUENCY FIELDS
The TRACER is designed in three versions with the following power options:
2.4 GHz @ 100 mW
2.4 GHz @ 1 W
5.8 GHz @100 mW
These levels of RF energy are below the Maximum Permissible Exposure (MPE) levels specified in FCC
OET 65:97-01. The installation of high gain antenna equipment in the system configuration may create
the opportunity for exposure to levels higher than recommended for the general population at a distance
less than 15 feet (4.6 meters) from the center of the antenna. The following precautions must be taken
during installation of this equipment:

Radio Frequency Interference Statement
ii
• The installed antenna must not be located in a manner that allows exposure of the general
population to the direct beam path of the antenna at a distance less than 15 feet (4.6 meters).
Installation on towers, masts, or rooftops not accessible to the general population is recommended;
or
• Mount the antenna in a manner that prevents any personnel from entering the area within 15 feet
(4.6 meters) from the front of the antenna.
• It is recommended that the installer place radio frequency hazard warnings signs on the barrier that
prevents access to the antenna.
• Prior to installing the antenna to the RFC output, make sure the power is adjusted to the settings
specified in section 2 of this manual.
• During antenna installation, be sure that power to the TRACER equipment is turned off in order to
prevent any energy presence on the coaxial connector.
• During installation and alignment of the antenna, do not stand in front of the antenna assembly.
• During installation and alignment of the antenna, do not handle or touch the front of the antenna.
These simple precautions must be taken to prevent general population and installation personnel from
exposure to RF energy in excess of specified MPE levels.
