Repeater
The repeater amplifies and transmits signals of the base station in the desired
area.
Outdoor ANT
The outdoor antenna connects to the Outdoor Port on the repeater.
PWR
Exterior adapter having AC 95-265 V input, supplies DC 9 V power to the
repeater to run active circuits. LED on
DC Jack
DC Jack is a terminal to supply required powers into repeater through the power
supply adapter.
Indoor Antenna
Indoor Antenna transmits the RF signal from base station to the cellular
subscriber and receives the signal from cellular subscriber back to the base
station. The indoor antenna, or transmitting antenna, connects to the Indoor
Port of the repeater.
RG8X Low Loss RF Cable
RG8X RF Coax Cable is supplied to connect the Indoor unit to the outdoor
donor antenna.
Mounting Bracket
Bracket with screws is supplied for fixing the indoor repeater to a wall.

How to install the system
Installation procedure
Identify installation location for both outdoor antenna and indoor unit
Measure signal strength of proposed location for donor antenna outside
Install donor antenna and route coax cable
Connect power supply adapter
Completion
Test
for call quality
Inspect system
and adjust donor
antenna
Check contents of package
Fix repeater to the wall
Adjust donor antenna on roof for optimum signal strength & call quality

Checking the contents supplied
Identify a suitable location where you would like mount the indoor
repeater
Ensure the location is properly isolated from the donor antenna and the
cable length supplied is sufficient.
Locate a suitable location for the outdoor donor antenna and identify a
route for the feeding cable.
Measurement of Receiving Level from Base Station (For Anyone)
A low-tech way to determine where to install your outdoor “donor” antenna is
to identify a spot where you are getting at least 2-3 bars of signal on your roof.
Then try to make 3 consecutive calls on your mobile phone in the proposed
location. If this is successful, then you may proceed with the installation.
Connect to RG 8X RF Cable
Connect power supply adapter
Adjust the direction of the donor antenna.
To improve calling qualities, adjust the direction of the donor antenna.
Testing for calling qualities

Troubleshooting
1) The power LED at the front turns OFF
Causes
Action
Power cable of the power supply
unit has not been connected.
Check connection of power system
2) The repeater transmits no signal
Causes
Action
Signal Cable from outdoor
antenna has not been
connected.
Check all connections.
Coaxial cable connecting the
repeater and outdoor antenna
might be defective
Make sure there is no sharp bends, or
breaks in the cable. If needed, replace
coaxial cable
