WARNING. This is NOT a CONSUMER device. It is designed for installation by
FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC
LICENSE or express consent of an FCC License to operate this device.
Unauthorized use may result in significant forfeiture penalties, including
penalties in excess of $100,000 for each continuing violation.
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 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 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.
WARNING!
Use only authorized and approved antennas, cables and/or coupling devices!
The use of unapproved antennas, cables or coupling devices could cause
damage and may be of violation of FCC regulations. The use of unapproved
antennas, cables and/or coupling devices is illegal under FCC regulations and
may subject the user to fines.
RF Exposure Warning: This equipment complies with FCC radiation exposure
limits set forth for a controlled environment. The Remote Unit should be
operated with a minimum distance of 28cm (11 in) between antenna and your
body.
Use only authorized and approved antennas, cables and/or coupling devices!
The use of unapproved antennas, cables or coupling devices could cause
damage and may be of violation of FCC regulations.
Note to the professional installer: the output power must be adjusted such that it does not
exceed the certified level as indicated in the certification filing to ensure that the booster is
operating in its linear range. Furthermore, the external antenna model come with a 9 dBi
panel type antenna which has been evaluated and fully comply with the relevant FCC rules.
The use of any other antenna is subject to a separate evaluation to ensure that the
resulting EIRP does not exceed the allowed EIRP limit as specified in 47 CFR Part
24.238(a) for LTE Band 25 and Part 27.53(h) for LTE Band 66 and that it complies with the
uncontrolled RF exposure limit.
