1.5 FCC Notification
This device complies with part 27 of the FCC rules.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
Note: 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:

Caution pertaining to the 4G output terminals:
This device is subject to different restrictions whether it is operated as a mobile terminal or as a
fixed station. When this device is operated as mobile subscriber equipment, the peak equivalent
isotropically radiated power (EIRP) shall not exceed 2 watts. As the default maximum conducted
output power of the device is near the allowed 2 Watts, it is required that this maximum power be
reduced by a ratio corresponding to the gain of the antenna used. For example if the 4G antennas
installed have a 5 dBi gain, the output power shall be reduced by the equivalent 5 dB, making the
conducted maximum output power 0.63 Watt at the most.
When the device is operated as a fixed station, the antenna gain shall be such that the EIRP is
limited to 40 Watts.
This configuration shall be executed by a professional installer.
