ADMONISHMENTS

Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times.

These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence.

Danger: Danger is used to indicate the presence of a hazard thatwill cause severe personal injury, death, or substantial property damage if the hazard is not avoided.

Warning: Warning is used to indicate the presence of a hazard thatcan cause severe personal injury, death, or substantial property damage if the hazard is not avoided.

Caution: Caution is used to indicate the presence of a hazard thatwill orcan cause minor personal injury or property damage if the hazard is not avoided.

GENERAL SAFETY PRECAUTIONS

-

Warning: Wet conditions increase the potential for receiving an electrical shock when installing or usingelectrically-poweredequipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm.

Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transceiver of any digital unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transceiver or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the adapter or connector.

Caution: This system is a RF Transmitter and continuously emits RF energy. Maintain 3 foot (91.4 cm) minimum clearance from the antenna while the system is operating. Wherever possible, shut down the RAN before servicing the antenna.

Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtails without severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bent or curved to a radius of less than 2 inches (5.1 cm).

Caution: Exterior surfaces of the RAN may be hot. Use caution during servicing.

SAFE WORKING DISTANCES

The Digivance NXD antenna, which is mounted on top of a pole, radiates radio frequency energy.

For the occupational worker, safe working distance from the antenna depends on the workers location with respect to the antenna and the number of wireless service providers being serviced by that antenna.

Emission limits are from OET Bulletin 65 Edition 97-01,Table 1 A.

STANDARDS CERTIFICATION

FCC: The Digivance NXD complies with the applicable sections of Title 47 CFR Part 15, 22, 24 and 90.

The Digivance NXD Hub 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.

Changes and modifications not expressly approved by the manufacturer or registrant of this equipment can void your authority to operate this equipment under Federal Communications Commissions rules.

In order to maintain compliance with FCC regulations, shielded cables must be used with this equipment. Operation with non-approvedequipment or unshielded cables is likely to result in interference to radio & television reception.

ETL: This equipment complies with ANSI/UL60950-1Information Technology Equipment. This equipment provides the degree of protection specified by IP24 as defined in IEC Publication 529. Ethernet signals are not for outside plant use.
