Opening the BDA (bi-directional amplier) could result in electric shock and may cause severe injury.
WARNING! EXPOSURE TO RF
Working with the repeater while in operation, may expose the technician to RF electromagnetic elds
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 elds.
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 8 inch while operating near the donor and the server antennas.
Also, the donor antenna needs to be mounted outdoors on a permanent structure.
WARRANTY
Unauthorized opening or tampering the BDA will void all warranties.
One-year Warranty will start when the ownership of CoverCell25K/100K700 is transferring.
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.
1. Using a pencil, mark the location of each of the mounting bracket's four mounting holes on the wall.
2. Drill holes in the wall at the locations marked in step 1.
3. Set the anchors in the wall using a hammer.
4. Locate the four mounting bolts and place a lock washer and at washer on each bolt.
5. Place the mounting bracket over the four holes with anchors, making sure that the washers are on the
repeater side of the mounting bracket. Tighten bolts until secure.

(1) Setting the direction of Donor Antenna
(2) A donor antenna needs to be located in a place which maintains maximum receiving signal
levels and attains highest Ec/lo values from BTS.
Donor ANT
Coverage ANT
(3) It is recommended that the antenna needs to be protected by placing it under the protection
angle from a lightening rod.
(4) A donor antenna needs to be away from high pressure and high frequency facilities.
When installing a donor antenna, it needs open spaces at least more than 180 degree.
(5) To get enough isolation between a donor antenna and a coverage antenna, those antennas
needs to be away from each other.
(1) Choosing an efcient emitting place – It is recommended that the antenna should not be
blocked by objects.
(2) For signal quality, the cable length needs to be as short as possible.
(3) The antenna needs to be away from other radio frequency radiating objects such as other
antennas, and CCTV equipment.

1. Antenna only (AGS setting) is for Auto Gain Setting to optimize this repeater for eld conditions
a. Every limit level (AGC, Down/Uplink ALC) is normal (example : Standard output power)
b. Auto Gain Setting will run
2. DAS (ALC downlink Limit 7dBm Setting) option is used for connecting this repeater to DAS equipment (LGC DAS,
Mobile Access DAS etc), and following condition should be controlled.
a. AGC turn Off
b. ALC turn On
c. Gain Balance turn Off
d. ALC downlink limit value set +7dBm
e. ALC uplink limit value set normal output power (example : Standard output power)
f. Shut down turn On
g. HPA turn On, If HPA turn off
h. delay alarm reporting time set 5 min
CAUTION
!
Please make Path On when you run Setup Wizard if Path Off set
3. DAS (ALC downlink Limit Maximum Setting) option is used for connecting Passive DAS equipment, and 7dB downlink
limit value is set as normal output power level
(Example: Standard output power)

Installer should wait about 2 minutes for upgrade to initialize.
• User may then be prompted to log back into the Repeater.
Warning: Exposure to Radio Frequency Radiation The radiated output power
of this device is far below the FCC radio frequency exposure limits.
Nevertheless, the device should be used in such a manner that the potential
for human contact during normal operation is minimized. In order to avoid
the possibility of exceeding the FCC radio frequency exposure limits, human
proximity to the antenna should not be less than
operation. The gain of the antenna is 8 dBi.
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
