The general safety information in this guideline applies to both operating and service personnel. Specific warnings and cautions will be found in other parts of this manual where they apply, but may not appear in this summary. Failure to comply with these precautions or specific warnings elsewhere in the manual violates safety standards of design, manufacture, and intended use of equipment. Cellular Specialties, Inc. assumes no liability for the customer's failure to comply with these requirements. 1.0 MANUAL610AMPS OMNI 4 PRODUCT DESCRIPTION Cellular Specialties, Inc. developed the Model 610 amps In-Building Amplifier (IBA) for use in enclosed structures where sufficient signal from local cell sites to operate cell phones was unavailable within the building. It is, of course, necessary that sufficient signal be available on the roof of the structure. The IBA is connected to an external antenna, usually on the roof, and to one or more internal antennas placed strategically throughout the area where phone service is desired. The external antenna is an omni-directional antenna, used when the building is located in close proximity to one or more cell sites. Internal antennas are usually omni-directional although various other types may be used for certain installations. The IBA amplifies both the "uplink" (phone to tower) and "downlink" (tower to phone) signals thus facilitating communications to and from the local cell site There are seven amplification stages on the downlink and seven on the uplink for a total of +85dB nominal gain for each link. (see Figure 2.1) Both links have manual gain control settings accessed through DIP switches on the top cover plus an AGC control for both the uplink and downlink. There are also LED indicators on the top cover for power on, transmitter on, uplink overload and downlink overload. An automatic amplifier safety shutdown circuit is also present that will disable the transmitters for ten seconds should the uplink or downlink overloads be reached to prevent excessive intermodulation and oscillation. 2.0 MANUAL610AMPS OMNI 5 I O INSIDE ANTENNA OUTSIDE ANTENNA AC INPUT MONITOR FCC / IC LABEL SERIAL NUMBER MANUAL610AMPS OMNI 6 GENERAL SPECIFICATIONS All specifications stated as typical unless otherwise noted.

MODEL 610 AMPS Bi-DIRECTIONAL AMPLIFIER FCC ID LABEL FCC ID NVRCSI610-02 IC: 4307A-610BDA This device complies with parts 22 and 2 of the FCC rules and with Industry Canada specification RSS-131

Evaluation of the CSI Model 610 amps BDA For Compliance with FCC Guidelines For Human Exposure to Radio Frequency Electromagnetic Fields 14 September, 2002 General The CSI Model 610 amps Bi-directional amplifier is considered to be a “mobile” device operating in the Cellular Service authorized under subpart H of part 22. As such, the equipment is required to be evaluated for RF exposure if operated below 1.5 GHz with an effective radiated power (ERP) of 1.5 watts or more, as defined in 2.1091 of FCC rules. Downlink For the downlink portion of the Model 610 amps BDA, the maximum rated output power is +30.6dbm (1.15 W). As stated in the Model 610 amps Manual, the maximum authorized antenna gain is 3 dBi, corresponding to a typical Omni-Directional antenna. Neglecting cable losses, the worst-case EIRP will be 2.30 watts or an ERP of 1.40 watts, (ERP=EIRP/1.64). This is below 1.5 watts and therefore excludes the downlink from routine evaluation. The Cautions in the Model 610 amps manual clearly define the antenna selection and installation criteria in order to maintain a minimum 20-centimeter separation. Uplink For the uplink portion of the Model 610 amps BDA, the maximum rated output power is +28.8dbm (750 mW). As stated in the Model 610 amps Manual, the maximum authorized antenna gain is 3 dBi, corresponding to a typical Omni-Directional antenna. Neglecting cable losses, the worst-case EIRP will be 1.50 watts or an ERP of 0.92 watts, (ERP=EIRP/1.64). This is well below the 1.5 watts and therefore excludes the uplink from routine evaluation. The Cautions in the Model 610 amps manual clearly define the antenna selection and installation criteria in order to maintain a minimum 20-centimeter separation.
