Note: 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 may 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 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.
Note: Whenever any FreeWave Technologies module is placed inside an enclosure a label
must be placed on the outside of that enclosure which includes the module's FCC ID.

A. Transceiver installation steps
To install the FGRplusRE transceiver, follow the basic steps given below.
1. Mount the transceiver to the flat, stable surface using mounting holes in the corners of the
transceiver. Transceiver models sold under FCC ID KNY-6231812519 are to be installed
professionally in NEMA enclosures.
2. Install the antenna and connect the antenna feedline to the transceiver. If you are installing a
directional antenna, preset the antenna’s direction appropriately. The antenna must be
professionally installed on fixed-mounted permanent outdoor structures for satisfying RF
exposure requirements.
Connect a computer to the transceiver’s RJ45 port or to an Ethernet connection on the same
3.
network segment as the transceiver (please refer to the Plus manual for additional
information). This computer will be used to set the radio configuration.
4. Install the power for the radio.
5. Connect to the transceiver’s Web page and set the radio configuration according to the
system topology and data terminal equipment requirements. Default transceiver settings
allow users to do a quick installation without major changes in transceiver’s configuration.
However, there is one parameter that must be considered for a new installation – the
transceiver’s power output setting. (“Transmit Power”. Radio Setup page >
Transmission Characteristics section.)
Transceiver output power level must be set according to the tables given below to satisfy
FCC maximum EIRP requirement. Per FCC regulations, any antenna used with FreeWave
transceivers must either be one of the approved antennas shown below or an antenna
approved by FreeWave Technologies with comparable performance parameters. FreeWave
Technologies offers a variety of omni-directional and directional external antennas, with both
bracket and magnetic mounts. The complete list of antennas available from FreeWave
Technologies including antenna gains, antenna manufacturer’s information and antenna’s
characteristics is shown below:
The following antennas are approved for use with FreeWave FGRPlusRE model transceivers:

NOTE: Use of any antenna with a gain higher than 6 dBi requires enough loss in the cabling
and connectors to keep the total gain within 6 dB, so that the radio can be run at full
power.

instructions).
9 Click the “Radio Setup” Link.
9 Choose an appropriate setting in “Transmit Power”, as defined from the previous tables.
9 Click the “Save Changes” button. After the page refreshes, click the “Reboot” button and
wait for the transceiver to restart.
6. Repeat the steps above for each transceiver in the network.
NOTE:
Please, be advised that antennas other than listed in this section can potentially be
used with the transceiver provided that:
• these antennas are of a similar type to the listed above;
• antenna gain does not exceed 8.15 dBi for omni-directional and 12.15 dBi for
directional antennas
• overall system EIRP does not exceed 36 dBm.
WARNING:
Any antenna other than listed in this section needs to be approved by
FreeWave Technologies before its use to assure that the transceiver in
combination with the new antenna meets FCC requirements.
B. Transceiver Location
Placement of the FreeWave transceiver is likely to have a significant impact on its performance.
In general, the rule of thumb with FreeWave is that the higher the placement of the antenna the
better the communication link - height is everything!
transceiver away from computers, telephones, answering machines, and other similar equipment.
To improve the data link, FreeWave Technologies offers directional and omni-directional
antennas with cable lengths ranging from 3 to 200 feet.
In practice you should also place the

When using an external antenna, placement of that antenna is critical to a solid data link. Other
antennas in close proximity are a potential source of interference; use the Radio Statistics or
Diagnostics software to help identify potential problems. It is also possible that slight adjustments
in antenna placement (as little as 2 feet) will solve noise problems. In extreme cases, such as
when the transceiver is located close to Pager or Cellular Telephone transmission towers,
FreeWave offers a band pass filter to reduce the out of band noise.
C. Diagnostic ports:
The FGRplusRE does not use the diagnostic port. The radio cannot be programmed through
the diagnostic cable.
D. Power Connection
The FGRplusRE transceivers can be operated from any Class 2 power source, input voltages of
6V to 30V. The power source should be capable of providing at least 550 milliamps of continuous
current at 12V DC.
Transceiver is designed to operate in negative ground systems only.
