Product Manual
Indoor Signal Repeater (Signal Booster) series is an ideal solution for wireless system in small/medium businesses and home users looking to enhance indoor wireless connectivity. It is connected via coaxial cable to Donor Antenna and Service Antenna, Donor Antenna is placed outside the building where it has easy access to BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind area. And Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network. With good looking & super compact design also make it attractive. Besides, it is easy installation feature is also for individual customers to install the booster by themselves, and it does not need much professional knowledge and instrument. The dual band improves mobile signals with no negative impact on human health.
Features
1. Cost effective solution for weak signal zones, reduce drop/off calls.
2. Compact size, low power consumption, easy installation, great cover. Expansion and extending of the signal of base station. Opti mization of the quality of the signal and source
3. Cover about 400m² without block or obstruct.
4. High linear design, ALC function design, low interference to BTS.
5. Support any cellular devices (voice & data & video)
6. Wide band signal booster, or customize selective band booster.
Advantages:
Digital Display Panel, Intelligent mode setting
Smart function called which can be activated via the digital display panel.
Users can choose gain and working system by LED Digital Panel.
Set the technical parameters simple and efficient, this is easier than DIP Switch.
Standard Package:
1) AC90-264V, DC 9V/5A power supply adapter 1PCS
2) AC power cord (EU/US/UK/SA/China standard, etc) 1PCS
3) Installation kit 1PCS
4) User manual 1PCS
Method of Installation:
The booster is fixed onto the wall through expansion bolts.
A. Drill holes on the selected place and install expansion bolts.
B. Align the holes with the expansion bolts, place flat washers, spring washers, and nuts in turn, and tighten the nuts to fasten the installing support.
C. Place the booster on and fasten it.
D. Connect cables and power cables to the booster respectively.
E. After installing the booster as described above, power on the booster to check the operation status.
Q1. Why is there still no signal after installing the equipment?
1. Check the power on booster and power supply.
2. Check the connector of outdoor antenna is tight or not.
3. Check the connectors of RF cable are tight or not.
4. Check the outdoor signal is strong enough or not.
5. Check to make sure the antenna is installed correctly.
6. Check the connector of indoor antenna is tight or not.
7. Check the cable type is suitable or not.
Q2. Why the signal strength is too weak on the edge of area?
1. Check the outdoor signal and antenna direction.
2. Check booster is full gain or not.
3. Check all of the connectors are tight.
4. Change the location of outdoor/indoor antenna.
5. Check the cable type is suitable or not.
6. Deploy more indoor antennas.
Q3. After running booster, why the signals are not stable?
1. Checking the distance between donor antenna and server antenna are too close to each other? Check LED
of booster to make sure alarms are green.
2. Checking the signals from donor antenna whether to be stable or not?
3. Connect the system again if it is incorrect connection.
Q4. Why the booster power LED is not bright?
1. Checking the input AC power range indicated on power adapter whether is corresponding to the local
power system.
2. Checking the power adapter whether connect the equipment correctly and stably or not.
3. Checking the power adapter whether damage or not. To test output voltage whether be corresponding
to that indicated onpower adapter or not by multimeter.
