EXPOSURE TO RFWorking with the repeater while in operation, may expose the technician to RF electromagnetic fieldsthat exceed FCC rules for human exposure. Visit t he FCC website at http://www.fcc.gov/oet/rfsafety to learn more about the effects of exposure to RF electromagnetic fields. Warnings and Hazards WARNING! ELECTRIC SHOCKOpening the BDA (bi-directional amplifier) could result in electric shock and may cause severe injury.WARNING! DAMAGE TO EQUIPMENTOperating the BDA with antennas in very close proximity facing each other could lead to severe damage to the repeater.RF EXPOSURE & ANTENNA PLACEMENTActual separation distance is determined upon gain of antenna used.Please maintain a minimum safe distance of at least 8inc h while operating near the donor and the server antennas. Also, the donor antenna needs to be mounted outdoors on a permanent structure.WARRANTYOpening or tampering the BD A will void all warranties. CAUTION: REPEATER SHOULD BE INSTALLED AS CLOSE AS POSSIBLE TO POWER SOURCE.CAUTION: THIS REPEATER IS FOR INDOOR USE ONLY AND SHOULD BE LOCATED INSIDE OF BUILDING.CAUTION: RISK OF EXPLOSION IF BATTERY ON CONTROLLER BOARD IS REPLACED WITH AN INCORRECT TYPE.CAUTION: DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS 5 Version 1.0 * May 2011 <Picture 1> M ounting th e Bracket on a Wood-Framed Wall. Mounting Repeater Wood-Framed Wall• It is recommended to first attach a sheet of plywood to the wall. The sheet of plywood should be anchored to the studs in the wall. • Using a pencil, mark the location for each of the mounting bracket's four mounting holes on the plywood.• Place the mounting bracket over the four lag screws heads.• Thread a lag screw at the positions marked in step 2. 6 Mounting Sems Screw M6 x 10mm Wood-Framed Wall Extension Mounting Bracket Version 1.0 * May 2011 Hang and Grounding <Picture 2> Hanging the PSU Unit. • Hang the PSU unit to the mounting bracket.• Locate the two Mounting Sems Screws (M6 x10mm) underneath the PSU unit. Tighten bolts until secure. Mounting Sems Screw M6 x 10mm 7 Version 1.0 * May 2011 Hang and Grounding • Hang the rest of the units in the following or der: 2600AMP, DFM 2. • Locate the two Mounting Sems Screws (M6 x10 mm) underneath each unit. Tighten bolts until secure. <Picture 3> Hanging the Rest of Units. CAUTION Units must be hung in the following order only: 2600 AMP -> DFM 2 8 Version 1.0 * May 2011 Hang and Grounding Ground Cable • Connect ground cables of each unit to the bracket using Ground Sems Screws (M4 x 8mm) as displayed at the picture below. CAUTION Ground cables must be properly grounded to provide both EMI and voltage surge protection for the repeater. <Picture 3> Grounding of the PSU, 1900 AMP, DFM 1, 800/900 AMP, 2600 AMP, DFM 2 Units. 9 Version 1.0 * May 2011 Hang and Grounding <Picture 4> Grounding the Bracket. • Locate the ground lug on the underside (or side) of the bracket.• C rimp the ground cable to the ground lug. • Route the free end of the ground cable to an approved (per local code or practice) ground source. CAUTION Ground cable must be properly grounded to provide both EMI and voltage surge protection for the repeater. 10 Version 1.0 * May 2011 Position Antenna • After installing 2600MHz antennas the installer should make line of site. • Customer specifications should be fo llowed for positioning the antennas properly Warning: In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna should not be less than 20cm during normal operation. The gain of the antenna is 12 dBi. . <Pi cture 5> An installer is directing Donor Antenna to nearb y BTS to receive strong input signal. 11 Version 1.0 * May 2011 RF Cable Connections: Top of The Repeater CAUTION Do not connect or disconnect cable from ANT port when power is ON. • Connect the 2600 Donor Antennas to their corresponding ports.• Plug in four N(M) to N(M) type RF cables as demonstrated in the picture below. <Picture 6> Top View of the Repeater. 12 AB C D SERVER ANT DONOR ANT Do not connect or disconnect cable to/from ANT port when power is ON CAUTION Do not connect or disconnect cable to/from ANT port when power is ON CAUTION SERVER ANT DONOR ANT Do not connect or disconnect cable to/from ANT port when power is ON CAUTIONDo not connect or disconnect cable to/from ANT port when power is ON CAUTION 800/900 2600 SERVER ANT DONOR ANT DONOR AMP SERVER AMP 2600 1900 1900 800/900 1900 800/900 2600 Wi-Fi SERVER ANT DONOR ANT Do not connect or disconnect cable to/from ANT port when power is ON CAUTION Do not connect or d…
