1. FCC Mandatory
1.1 FCC Warning States
1.1.1 FCC Part 15.21
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
1.1.2 FCC Part 15.105
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to correct
the interference at his own expense.
1.1.3 FCC Part 15.19
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.
1.1.4 Antenna installation
. Antennas must be installed in accordance with FCC requirement.
The height of the antenna above average terrain (HAAT) must not exceed limit in the
following table.
