In either case, you should try power cycling the booster after re-aiming the outside antenna to ensure that the booster isn’t shutdown due to conditions at the previously aimed direction. If the warning is due to overload (too strong of a signal coming from a nearby tower), then the aiming process will still work correctly by helping you find the direction where the system performs the best. If the warning light is due to oscillation (feedback), try retesting in that direction but increase the separate between the inside and outside antennas. If, while testing, you find that there are warning lights on the booster, consult your owner’s manual for information on what caused the warning. Handling Warning Lights During the Testing Process Ideally, you want the antenna on that side of the building pointing away from the building. Once you’ve identified the correct direction, find a location to mount the antenna so it can point in that direction with as few of obstacles as possible. The stronger the signal, the more coverage you’ll get from the system. For example, a -70 dB reading is better than a -90 dB reading. If you took decibel readings, then look for the readings that are closest to 0. Once you have the signal readings, you’ll want to find the direction that gave you the strongest readings for al of the carriers that you want to support. Repeat this process until you’ve aimed the outside antenna in all 8 directions and have 8 sets of signal readings.Once the antenna has been rotated 45 degrees, the person inside should again wait 60 seconds and then take another set of signal readings. This can correspond to the 8 compass points (N, NE, E, SE, S, SW, W, NW). Next, rotate the outside antenna 45 degrees or 1/8th of the way around.It’s also a good idea to check the warning lights on the booster to record any warnings you see. The person inside should then wait 60 seconds and then record the signal readings from the phone(s).
