User's Manual Part 2

B.4 Human Exposure to RF
The following precautions apply to LGCell products.
• LGCell has no user-serviceable parts. Faulty or failed units are fully
replaceable through LGC Wireless. Please contact us at 1-800-530-9960. For
international customers, please contact us at [phone].
• Never input an RF signal to the Main Hub Duplex port that is higher than those
defined on page17 in Section 2, LGCell Equipment.
• Although modeled after an Ethernet/LAN-like architecture and connectivity,
LGCell units (Main Hub, Expansion Hub, and the Remote Antenna Unit) are
not intended to connect to Ethernet data hubs, routers, cards or other similar
data equipment.
• For improved air circulation, be sure to leave at least one inch (25 mm) of
space between all hubs and between any other equipment in the rack. If
mounting a hub on the rack’s bottom shelf, also leave at least a one inch of
clearance from the bottom.
• When you connect the Multi-Mode Fiber (MMF) Optical Cable, take the same
precaution as if installing Ethernet network equipment. All optical fiber ST
connectors should be cleaned according to the cable manufacturer’s
instructions.
• When you connect a radiating antenna to an RAU, DO NOT over-tighten the
SMA connector. Firmly hand-tightening the connector is adequate.
Antenna gain is restricted to 1.5 W ERP (2.49 W EIRP) in order to
satisfy RF exposure compliance requirements. If higher than 1.5 W
ERP, routine MPE evaluation is needed. The antennas should be
installed to provide at least 20 cm from all persons to satisfy MPE
requirements of FCC Part 2, 2.1091.
To reduce the risk of fire or electric shock, do not expose this
equipment to rain or moisture.
