WARNING! EXPOSURE TO RF
Working with the repeater while in operation, may expose the technician to RF electromagnetic fields
that exceed FCC rules for human exposure. Visit the 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 SHOCK
Opening the BDA (bi-directional amplifier) could result in electric shock and may cause severe injury.
WARNING! DAMAGE TO EQUIPMENT
Operating the BDA with antennas in very close proximity facing each other could lead to severe damage to the repeater.
RF EXPOSURE & ANTENNA PLACEMENT
Actual 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.
WARRANTY
Opening 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 INSTRUCTIONS

<Picture 1> Mounting the 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.

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.

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.
CAUTION
Units must be hung in the following order only: PSU -> 1900 AMP
8
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, 800/900 AMP Units.

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.
CAUTION
Ground 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 to
nearby BTS to receive strong input signal.

RF Cable Connections: Top of The Repeater
CAUTION
Do not connect or disconnect cable from ANT port when power is ON.
• Connect the 1900 Donor Antennas to their corresponding ports.
• Plug in four N(M) to N(M) type RF cables as demonstrated in the picture below.

RF Cable Connections: Bottom of The Repeater
• Take out three SMA (M) to SMA (M) type RF cables.
• While connecting the PSU and the DFM units underneath, use referenced cable and pay attention to the labels. Plug them into
their corresponding outlets.
• User may choose either of the two SMA ports on the bottom of the PSU to connect to the DFM.
• User may choose any two of the four SMA ports on the bottom of the PSU to connect to amplifiers.
CAUTION
Please, pay attention while connecting PSU and DFM, PSU and 1900 AMP units. The repeater will not work if
connection is inappropriate.

• 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 be
manually set. Attenuation may also be added for reducing power levels. ALC also provides optional U/L and D/L
settings.
- 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 a
process 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.

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. The antenna(s) used for this
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
