10.Supporting multiple phone users.
Accurate display of outdoor signal strength, voltage conditions to make the data more accurate and more convenitent.
Situation A: If the empty signal box flashes, it proves that the signal wasn’t received successfully.
Situation B: If the signal shows a value of 80, it means that 80% of the signal is received.
Situation C: If the signal shows a value of 100, it means that 100% of the signal is received.
Situation D: If the signal grid is filled, it means that the device recieve full signal. Maybe self-oscillation. If the signal of your mobile phone is strengthened, that's perfect. If isn't, that means it's self-oscillation.
PS: If you have any other confused when you using it, please contact customer servive at once.

The metal case design make it sturdy and durable. Bump heat dissipation design for better heat dissipation.
Beautiful Appearance: New style, big screen, unique design, is not only a cell phone signal booster but also an artwork. It can be used for apartment, hotel, office, basement of buildings, coffee shop and shopping mall etc.
With the difference frequency of the booster, antenna need to be match so that it can work.
The ceiling antenna is of 360° coverage, and the gain is higher than whip antenna which is directional coverage.You may installed the ceiling antenna in the place where you want to receive signal. Comparing with the whip antenna which only can install following to the booster, it's better.
Step1:Search a position where can receive good signal(stronger than -70dB)Parallelly installing the outdoor antenna on that location,towards to the base station or cell tower.
Step2: Use 10m cable to connect the outdoor antenna and singal booster.Please ensure they were tightenned joints,connected well. Step3:Connect the indoor antenna and the singal booster.
Step4:After finished all parts then check weather all connectors well,then can turn on the power.
Two antennas need to separate by brick wall. The distance between them at least 10 meters.
1. RECEIVES SIGNAL
The powerful antenna reaches out to access a good signal, and delivers it to the booster.
2. BOOSTS SIGNAL
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3. BROADCASTS SIGNAL
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
Question: no signal on the display and phone
Solution: adjust outdoor antenna, put it at a higher postion and make sure it could receive good signal from base station.Or please check the freqeuncy of your antenna, if you buy only booster from us. If the frequency doesn't match to the booster's, it could not work either.
Question: the display is blinking and signal light isn't on.
Solution: Also adjust outdoor antennna as above, because blinking means receiving signal is not stable. Adjust the position and direction of outdoor antenna until it stop working.
Queation: the signal is at maximum on booster but the signal on the phone does not improve at all
Solution: It is what we called "self-oscillation phenomenon". You need to increase the distance of indoor antenna and outdoor antenna and separae them with a brick wall. Make sure there is no opening area between them.
Question: The booster works properly but the signal light is not on
Solution: Maybe the cable is too long for the booster or the connection is not well. Please make sure all the antenna are connected well and tightly. It actually does n't matter too much as long as the device works well.
