WARNING – To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. Do not use this apparatus near water. Do not expose the apparatus to dripping or splashing. Do not place objects filled with liquids, such as vases, on the apparatus. The DAS-900 shall be connected to a main socket outlet having a protective grounding connection. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarizing or grounding type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or third prong is provided for your safety. When the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point of exit on the DAS-900. Only use attachments/accessories specified by the manufacturer. Unplug this apparatus during lightning storms or when unused for long periods of time. Refer all servicing to manufacturer. Servicing is required when the apparatus has been damaged in any way, for example if the power-supply cord has been damaged, liquid has been spilled or objects have fallen into the unit, or if it has been exposed to rain, moisture, does not operate normally, or has been dropped. A/C Power Warning: Users should exercise extreme care when working with electricity. Additional care should be used when working with electricity outdoors in inclement weather. When working outdoors or near water, always connect the system into a ground-fault interrupting circuit. There are no user- serviceable parts inside the DAS-900. Opening the case may expose dangerous electrical components, and will void the warranty. Important FCC and Safety Information I. Digital Device Statement A. The DAS-900 been tested and found to comply with the limits for Class B digital devices, pursuant to Part 15 of the Rules and Regulations of the U.S. Federal Communications Commission (the FCC) . This product is marketed as Class B digital device. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. B. This equipment generates, uses, and can radiate radio-frequency energy. If not installed and used in accordance with all instructions, it may cause harmful interference to radio communications. C. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his own expense. NOTE: 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. 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. II. Intentional Radiator Statement A. The DAS-900 is ONLY to be used with the modular, low-power radio transceiver module that operates pursuant to Part 15 of the FCC’s Rules. The DAS-900 can only be operated AS A COMPLETE SYSTEM under FCCID S85-DAS900 B. Operation is subject to the following conditions: 1. The DAS-900 system may not cause harmful interference to other users of the radio spectrum. 2. Upon notification by a representative of the FCC that a DAS-900 system is causing harmful interference, use of the system must be suspended. Operation must not resume until the condition causing the harmful interference has been corrected. 3. The DAS-900 system must accept any interference received, including interference that may cause undesired operation. C. The DAS-900 system must be used with only with the approved antennas listed below. Use of any non-approved antenna, or any modification to any part of the DAS-900 system violates the system’s warranty, and also constitutes a violation of the FCC’s Rules and Regulations and of § 302 of the Communications Act of 1934, as amended. D. To reduce potential radio interference to other…

However, in a normal operating configuration the antennas cannot be installed such that the patterns overlap. As worst case, even though not achievable for system operation, the directional gain calculation and maximum EIRP calculation were based collocated correlated transmissions. MPE Calculation The Power Density (mW/cm 2 ) is calculated as follows: S = 2 4R PG  Where: S = power density (in appropriate units, e.g. mW/cm2) P = power input to the antenna (in appropriate units, e.g., mW) G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) MPE Calculator for Mobile Equipment Limits for General Population/Uncontrolled Exposure* 914.6121.050.61127.4312.5317.906 200.454 Power Density (mW/cm^2) Distance (cm) Transmit Frequency (MHz) Radio Power (dBm) Power Density Limit (mW/Cm2) Radio Power (mW) Antenna Gain (dBi) Antenna Gain (mW eq.) Installation Guidelines The installation manual should contain text similar to the following advising how to install the equipment to maintain compliance with the FCC RF exposure requirements: RF Exposure In accordance with FCC requirements of human exposure to radio frequency fields, the radiating element shall be installed such that a minimum separation distance of 20 centimeters will be maintained. Conclusion This device complies with the MPE requirements by providing adequate separation between the device, any radiating structure and the general population.
