5. System Auto Level Control Algorithm
ALC(Automatic Level Control) operates at 1dB step to maintain the output level of 10dBm when the
input signal is from -60dBm to –30dBm.(30dB range)

6. System Operation
The Powertec RIF900 GSM “over the air” Repeater is designed for indoor operation to
increase signal strength in small and medium sized areas such as offices, shops and
basement car parks in the GSM band, with frequencies that are programmable to the
specific requirements of each site. It is small, lightweight, and easy to install. Simply plug it
in, and the coverage will be immediately extended. The uplink and downlink gain of the
repeater can be adjusted by ALC.

Installation Process
This is one of the most important process in repeater installation, as how to install the antenna
decides performance of this equipment.
1. Decide a place to install the outdoor antenna considering the cable
length of the donor antenna.
2. Attach the antenna bracket at the wall.
(Refer image A)

<Image A. Repeater Bracket and Direction of attachment>
3. Place the bracket to the repeater. Refer Image B.
<Image B. Repeater Bracket Placement>
4. Check the Receiving Signal by DONOR CABLE and connect to repeater’s DONOR
ANT PORT (Input Signal Receive Range –30~-60dBm)
5. Install the service antenna at the appropriate place and connect the cable with the
repeater.
6. Connect the adaptor to the repeater and check the POWER LED power on
status.

7. After 10 seconds, check of ALARM LED is ON. (When ALARM LED is on, it means
the system has been shutdown as external input signal strength is
too strong. Please refer the Trouble Shooting below and check the system status.)
8. At normal operation, the LED status indicates as below;
ALARM LED OFF/ POWER LED, FWD LEVEL LED ON
Operation Instruction
-Upon confirmation of electric power (100~240V/AC), insert AC cable to power supply,
then using DC cable, insert power cable to DC power input terminal, which is set on the
bottom of the equipment
LED Configuration
-Power : DC Power is normal -Green LED ON
-Alarm : FEW,REV over power, When Shut Down- Red LED ON
- FWD Level : FWD(Down Link) Indicates output Level-Green LED ON/OFF
-
No. of LEDs at ON status Condition ( Input Signal Level )
0 Less than -80dBm
1 -80~-76dBm
2 -75~-71dBm
3 -70~-66dBm
4 -65~-61dBm
5 -30~-60dBm

8. Trouble shooting
When Power LED (GREEN) off
1) Check the AC Power.
2) IF AC power is OK, Check the DC Power by checking Power Supply.
When Alarm LED (RED) ON
1) Check the Isolation between Donor ANT. and Service ANT.
When no LED blinks at FWD LEVEL LED
Check the FWD Input Power level whether it is in normal range.
9. Handling Procedures
-Please avoid using the other Power Supply besides included ones.
-Prohibited to use other frequencies antennas.
-Please refrain from installing the equipments reach of children.
