Shenzhen Fuzhixing Electronics Co Ltd NXA70 Cell Phone Signal Booster User Manual

Introduction:

The booster is designed to realize the wireless forwarding and bidirectional amplifying of the base station’s signal, expand the coverage of communication signal and cover its blind zone. When booster is working, the outside antenna (connecting to the OUTDOOR or BTS Port of booster) will receive the cell signal from signal tower and send the signal to the booster through coaxial cable; then the booster amplifies the signal and send the boosted signal to the inside antenna (connecting to the INDOOR or MS Port of booster); finally, the inside antenna could transmit the signal into your house.

The cell phone signal booster will only make a weak signal stronger,it can’t create a signal. It won’t work if the outdoor antenna can’t receive any signal.

The outdoor antenna should receive 2-3 bars of stable signal in the location where the outdoor antenna is fixed; otherwise, the booster won’t work very well.

1. Installation Location Requirement

2. It is important that the repeater is installed in a place where is away from excessive heat, direct sunlight, moisture and with proper ventilation. Do not place the repeater in an air-tighten closure.

3. Installation height should be easy for RF cable wiring, heat dissipation, security and maintenance.

4. There should be an independent and stable power supply.

5. Lightning protection is recommended for all in-building installations. Take extreme care to ensure neither you nor the antenna come in contact with any electrical power lines.stability

6. Installation of Outdoor antenna
   The repeater’s main function is improve weak RF signals of an area. A simple formula:
   Input power+ Gain=output power. The signal strength from the outdoor antenna directly affects the efficiency of the indoor coverage. it is very important to choose the outdoor antenna location in order to get the best signals.Testing the signal strength received from outdoor antenna by mobile phone: Select an outside antenna location on the roof of the building to install the outdoor antenna, using a cell phone to find the strongest signal from the cell tower.
   The phone calls or data transmission shall be smooth and stable by 3 times testing in location
   Fix the outdoor antenna after selecting the best position, and adjust height or angles slightly in order to get the best signal with suitable input power level and calling quality.
   Test the call quality of Outdoor antenna (for professional installation team only） Selecting the installation direction of outdoor antenna.
   The outdoor antenna should point in the direction of the tower, and it is much better to keep line of sight.
   Select opposite directions for outdoor antenna and indoor antennas. Please test the signal quality and make sure to avoid self-oscillation first, if have to install Outdoor and Indoor antennas in the same direction. If the directional antenna is selected, the main directional angle should point to the tower antenna.
   If the performance is poor due to weak signals or poor phone call quality, please adjust the direction of outdoor antenna or change its position in order to obtain the best calling effect.
   The wide band repeater supports all mobile operators or different mobile systems, so please adjust the outdoor antenna direction to have a balance between signals of different mobile operators or various mobile systems.
   Outdoor antenna installation—Notes:
   Do not install the outdoor antenna during the rainy day with lightning. Please follow the instructions to install the outdoor antenna.
   It is very important to waterproof the connectors of outdoor antenna and feeder lines.
   In order to avoid interference, please note that the outdoor antenna should be far away from objects of metal, high voltage line, RF antennas and high voltage transformer.
   Repeater is a tow-way signal amplifier. So proper isolation between outdoor antenna and indoor antenna is necessary to avoid self oscillation. (About the definition for self oscillation, take the MIC and loudspeaker for example, if it is too close for each other, it could make loud noise.)
   As shown in the below illustration, the booster amplifies the downlink signal from the tower and send to the indoor antenna hereafter. If the distance between outdoor antenna and indoor antenna is less than the required distance, the amplified signal R will go back from indoor antenna to outdoor antenna. So it will lead to self oscillation and reduce the coverage area, also the bad calling quality could happen at the same time, and the worse is that mobile network could be influenced badly and the operators will finally come to shut off the repeater system.
   The minimum distance between outdoor antenna and indoor antenna shall be more than 39ft; again, the direction of outdoor and indoor antennas shall be opposite. For example,

7. Connect cables to the booster’s ports after installing and fixing outside and inside antennas.Steps as below:

8. Open the cable package and make it bend naturally and smoothly.

9. Keep horizontal cables straight and fasten them with a fixing clip every 1 to 1.5 meters.

10. The cable should be bent naturally and smoothly to avoid cable damage caused by strong pulling.

11. RF cables should be separated from power cables; If the site condition are limited, installing RF cables and power cables together may affect product performance.

12. Tighten all cable connections to ensure a good contact.

13. Offer waterproof treatment to the exposed cable ends to avoid oxidation.

14. Finish the cable layout
    At last, plug the Power Supply into wall outlet and enjoy your boosted cell signal!

5. Check Coverage
   (1) PerformatestwithamobilephoneordatacardCheckbelow:

   • A weak input signal leads to the low output power. Need to change the direction of outdoor antenna or its installation position or replace outdoor antenna with higher gain antenna to increase input signal power level.
   • Check whether it is necessary to add more Indoor antennas’ sine barriers to block the signal penetration, and check whether the repeater’s power is enough.
   • InstallmoreIndoorantennasorreplacewitharepeaterofhigherpowerlevel。
     

6. The signal booster will only work with the correct frequency, so please make sure yourphonesignaliswiththesamefrequencyasthesignalbooster.

7. This cell phone signal booster will only make a weak signal stronger, it can’t create a signal. That means it won’t work if the outdoor antenna can’t receive any signal.

8. The outdoor antenna should receive 2-3 bars of stable signal in the location where the outdoor antenna is fixed; otherwise, the booster won’t work very well.

9. Must connect the antennas first, and then switch on the power; otherwise, may damage therepeater.

10. Determine the best location where the highest signal strength is received on your phone (most amount of bars). Once you ascertain the best location, then permanently mount the outdoor antenna. Keep the distance between the outdoor antenna and indoor antenna more than 39ft and make sure that there is a proper physical separation between the outdoor antenna and indoor antenna.
