Demarc Technology Group LLC DT100 Manuel D’Utilisation

 

Demarc Technology Group, LLC wireless equipment described herein complies with FCC radiation 
exposure limits set forth for an uncontrolled environment when installed as directed. The equipment should 
be installed and operated as fix-mounted system such that the main lobe(s) of these antennas are located a 
minimum of 8 feet between the antenna and all persons during normal operation. 
 
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: 

1.  This device may not cause harmful interference. 
2.  This device must accept any interference received, including interference that may cause 

undesired operation. 

 
Changes or modifications not expressly approved by the manufacturer could void the user’s 
authority to operate the equipment. 
 

This Equipment has been tested and found to comply with the limits for a Class B digital device, pursuant 
to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful 
interference in a residential installation. This equipment generates, uses, and can radiate radio frequency 
energy and, if not 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.  

 

The FCC does not require licensing to implement this device. However, the FCC has established 
restrictions regarding maximum output power and the adjustments required when employing directional 
gain antennas. These restrictions are detailed in FCC Part 15.247 (b)(1), (b)(3)(i), and (3)(iii). It is the 
responsibility of the individuals designing and implementing the radio system to assure compliance with 
these and any other pertinent FCC Rules and Regulations. 

The DT-ZM-100mW-WC is designed for 2.4 GHz @ 100mW. This level of RF energy are below the 
Maximum Permissible Exposure (MPE) levels specified in FCC OET 65:97-01.  This is only approved 
with the antenna gains as listed in this document with the maximum antenna gain of 15.7dBi.  A separation 
distance of 25 cm between the antenna and humans must be maintained.  

 
The following precautions must be taken during installation of this equipment: 

•  The installed antenna must not be located in a manner that allows exposure of the general 

population to the direct beam path of the antenna at a distance less than 25cm. Installation on 
towers, masts, or rooftops not accessible to the general population is recommended; or 

•  Mount the antenna in a manner that prevents any personnel from entering the area within 25 

cm from the front of the antenna. 

•  During antenna installation, be sure that power to the DT-ZM-100mW-WC equipment is 

turned off in order to prevent any energy presence on the coaxial connector. 

•  During installation and alignment of the antenna, do not stand in front of the antenna 

assembly. 

• 

During installation and alignment of the antenna, do not handle or touch the front of the 
antenna.

 

 
These simple precautions must be taken to prevent personnel from exposure to RF energy in excess of 
specified MPE levels.
