WARNING! EXPOSURE TO RFWorking with the repeater while in operation, may expose the technician to RF electromagnetic fieldsthat exceed FCC rules for human exposure. Visit the FCC website at http://www.fcc.gov/oet/rfsafetyto learn more about the effects of exposure to RF electromagnetic fields.Warnings and HazardsWARNING! 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 8inch 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 BDA 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 INSTRUCTIONS5
<Picture 1> Mounting the Bracketon a Wood-Framed Wall.Mounting RepeaterWood-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.Mounting BracketLag Screw1/2” x 2”Wood-Framed Wall6
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 10mm7
Hang and Grounding• Hang the rest of the units in the following order: 1900 AMP• Locate the two Mounting Sems Screws (M6 x10mm) underneath each unit. Tighten bolts until secure.<Picture 3> Hanging the Rest of Units. CAUTIONUnits must be hung in the following order only: PSU -> 1900 AMP 8
Hang and GroundingGround Cable• Connect ground cables of each unit to the bracket using Ground Sems Screws (M4 x 8mm) as displayed at the picture below. CAUTIONGround 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, 800/900 AMP Units.9
Hang and Grounding<Picture 4> Grounding the Bracket.• Locate the ground lug on the underside (or side) of the bracket.• Crimp 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.CAUTIONGround cable must be properly grounded to provide both EMI and voltage surge protection for the repeater.10
Position Antenna• After installing 1900MHz antennas the installer should make line of site. • Customer specifications should be followed 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 40cm during normal operation. The gain of the antenna is 12 dBi. <Picture 5> An installer is directing Donor Antenna tonearby BTS to receive strong input signal.11

• What is Auto Limit Control (ALC)?ALC is used for custom installations.If the repeater is having difficulties with isolation check, or if you want to “power down” the repeater ALC should bemanually set. Attenuation may also be added for reducing power levels. ALC also provides optional U/L and D/Lsettings.- ALC controls the output power.- If you want to use the ALC function, Gain Balance Control should be turned off.- ALC will reduce max gain by the set value even if the input signal decreases. - ALC should be used if the repeater is connected to a DAS system.• What does the Shutdown ON/OFF control?- An internal wave-detection is checking the noise level. If the repeater cannot secure isolation it will go through aprocess of turning itself off, and turning back on while doing isolation checking.- If it is impossible for the repeater to secure isolation after 30 minutes, the repeater will shut down and stay shutdown.The items that may automatically require the repeater to shut down are:-> VSWR Alarm, Over Power Alarm, Over Input Alarm, and Temperature Alarm.• What is Gain Balance Control?- Gain Balance Control will always keep the UL and DL ATT the same while using AGC.GBC should always be left on to prevent damage to BTS while using AGC.- This is used for BTS to cell phone power control.RF Configuration Menu FAQ’s41
