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:
• --Reorient or relocate the receiving antenna.
• --Increase the separation between the equipment and receiver.
• --Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• --Consult the dealer or an experienced radio/TV technician for help.
Interference Environment
Operation is subject to the following conditions:
• This device may not cause harmful interference and,
• This device must accept any interference received, including interference that
might cause undesired operation.
Operational Requirements
In accordance with the FCC Part 15 regulations:
1. The maximum average power output of the intentional radiator shall not
exceed one (1) watt (30 dBm) for all spread spectrum systems operating in
the 902 to 928MHz band.
2. Stations operating in the 902 to 928MHz band may use transmitting antennas
of directional gain greater than 6dBi, provided the average output power from
the intentional radiator is reduced by the amount in dB that the directional gain
of the antenna exceeds 6dBi.
3. The operator of a spread spectrum system and the user of the radio device
are each responsible for ensuring that the system is operated in the manner
outlined in Interference Environment on page xiii.
The EUM3006 with its integrated antenna complies with these requirements, since the
maximum average transmitting power is 25.8 dBm measured at the internal antenna port
which is not accessible to the user. This is 4.2 dB below the maximum allowed, so the
integrated, high-gain, active diversity antenna is allowed to provide an additional 4.2 dB gain
for a total of 10.2 dBi gain.
Warnings and Advisories
General Advisory
Installers, operators and maintenance personnel must be familiar with the related safety
requirements before they attempt to install or operate the EUM3006.
