r-series Installation and Management Manual

5000007 (ETS)

vii

2007-02-12 (draft)

The antenna associated with this device shall be mounted in a location that is at least 10'/3m
away from humans that may be subject to long-term or continuous exposure.

Europe/ITU (ETSI and CE Mark)

The EX-5r family complies with ETS 301 893 for the 5.3 and 5.47 GHz bands for license-
exempt use for most countries recognizing ETSI or ITU band assignments. These bands require
Dynamic Frequency Selection (DFS) and Transmitter Power Control (TPC) for radar-detection
and avoidance. There is a +30dBm EIRP limit applied to this band. Transmitter power must be
adjusted accordingly with respect to the RF cabling losses and antenna gains associated with
each terminal.

The EX-5r family complies with ETS 302 502 for the 5.8GHz band. This band is

not

yet

harmonized for all countries recognizing ETSI or ITU band assignments. Consult the individual
country regulations or your Exalt Communications representative for details. This band requires
DFS and TPC for radar-detection and avoidance. There is a +33dBm EIRP limit for use of the
10MHz BW setting (called 8MHz on GUI), and a +36dBm EIRP limit for use of the 20MHz BW
setting (called 16MHz on GUI).

All models comply with the requirements for CE Mark (EN 60950) and EMC (EN 301-489-17)
when used with the AC adapter included with each model. No substitutions shall be made, and
all wiring and grounding instructions contained in this manual must be followed to ensure safety
in accordance to the standards.

Regulatory Notices (4.9GHz Model)

The EX-4.9r is a licensed-band product operating within Part 90 of the FCC regulations and
RSS-111 of Industry Canada. These bands are specifically reserved for Public Safety
applications and related agencies, in accordance with these regulations.

Professional installation is required, and transmitter power reduction may be required, depending
on transmission system gains and losses, in accordance with instructions found in RF Output
Power Setting on page 10.

The transmitter power of the device must be reduced by 1dB for every 1dB that the antenna gain
exceeds 26dBi (inclusive of transmission system losses).
