Connect the indoor antenna to the MS port. 2. Connect the outdoor antenna to the BS Port. 3. Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna. 4. Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station. 5. Power on the booster and check the signal strength. 6. Adjust the outdoor antenna until you get the best signal strength. **IMPORTANT NOTE**: DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.
