FCC Notice, USA
Microwave Data Systems Digital Radios comply with Part 15 of the FCC rules. The radios are
specifically designed to be used under Part 15, Section 15.247 of the FCC rules and regulations.
Operation is subject to following conditions:
• The device to utilize a fixed mount antenna, for use on a permanent outdoor structure.
• The device to be installed by qualified installation/deployment personnel. When the
device is operating, a minimum separation must exist between the device and persons as
shown in the table below. The following method was used to calculate the RF safety
distance:
S
MPE
= PG/4πr
min
2
= EIRP/4πr
min
2
which is solved for the minimum separation distance
r
min
= (PG/4πS
MPE
)
1/2
= (EIRP/4πS
MPE
)
1/2
where P = power input to the antenna (mW), EIRP = Equivalent (effective) isotropic
radiated power, S = maximum permissible exposure (mW/cm
2
), G = numeric gain of the
antenna relative to an isotropic radiator, and r
min
is the minimum separation distance to
the center of radiation (cm). The resulting separation distances are dependent on
frequency band.
Frequency Band Minimum Distance (cm)
UNII Band (nominal frequency = 5.25 GHz) 54
ISM Band (nominal frequency = 5.725 GHz) 285
• The device installers and operators should be aware of the transmitter operating
conditions, specified in the installation manual and other associated user documentation,
as well as the antenna co-location requirements of Part 1.1307 (b) (3), of FCC rules,
pertaining to RF exposure.
• The device may not cause harmful interference.
• The device must accept interference received, including interference that may cause
undesired operation.
The device is intended to be used only when installed in accordance with instructions outlined in
this manual. Failure to comply with these instructions may void the user's authority to operate
this device and/or the manufacturer's warranty. Furthermore, any unauthorized modification or
changes to this device without the express approval of Microwave Data Systems may also void
the user's authority to operate this device.
FCC Part 15 Notice
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 may cause harmful
interference, in which case the user will be required to correct the interference at his expense.
Any external data or audio connection to this equipment must use shielded cables.
