Introduction                                                                                                              


Indoor Signal Booster series is an ideal solution for 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 a BTS signal, and the
Service Antenna is placed in the building where it can extend radio coverage to the blind area.

ISO(ALARM LED)GreenIt is working in linearity.
RedThere are strong input signals or severe self oscillation.
Please adjust the gain to see if it's too strong input signals;
After that, if it's still red, that means much closer distance between indoor and outdoor antenna, please put them in longer distance between antennas.

FAQ                                                                                                                     

1. After installing booster signal not be very good, indoor signal coverage very small ?
   > Adjust outdoor antenna
's location and direction

   > Change another high gain outdoor antenna
   > Check whether cables are connected well
   > Change more powerful repeater

2. Cell phone signal full bar, but communication quality bad ?
   > Much closer distance between indoor and outdor antenna, separate them with a longer distance.


3. After installing booster not only signal be good, but also more bad ?
  > Much closer distance between indoor and outdor antenna, separate them with a longer distance.


4. Working good for long time, suddenly signal bad ?
  >  Check whether outdoor cable connectors are flooded
  >  Check whether power light is working normally
  >  If cables are not flooded and power light is working normally, the booster should has problems and need to be sent back to factory for repair.
