#### 1

**Receives signal**  
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data 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.  
  

  

#### **Get stronger signal**

#### Normal Cell Coverage

Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.

#### Signal Coverage with our booster

Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.

#### **Installation**

1.  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.

1.  What is a Mobile Signal Booster? - A mobile signal booster is a device that helps improve your phone's signal indoors. If you have weak or no signal in your home or office, the booster can make it better. It takes the outside signal and amplifies it so you can have a stronger connection for calls and internet.
2.  How does the 4G LTE Booster work? - The 4G LTE booster works by receiving the weak mobile signal from outside your building and boosting it, making it stronger. This helps you get a better connection for calls and internet, especially if you live in an area with poor mobile service.
3.  Will the booster work if there is no signal outside? - No, the booster cannot create a signal on its own. This means if there is no signal outside, it won’t work inside either. You need some outside signal for the booster to help improve your connection indoors.
4.  How much area does the booster cover? - The booster is designed to cover an area of up to 100 square meters. This makes it great for small apartments or offices where you need better mobile signal.
5.  What kind of phones can use the 4G Calling feature? - The 4G Calling feature works with phones that support Voice over LTE (VoLTE). If you have a compatible phone and your area has 4G Calling available, you can make clearer voice calls with the help of the booster.
6.  Do I need to install the booster myself? - Yes, the booster kit comes with all the items you need for installation, and it's designed to be easy to set up! You just need to follow the instructions included in the kit.
7.  What is the Band Checker and how do I use it? - The Band Checker is a tool to help you see what frequency your phone is using. You can check this by dialing \*3001#12345#\* on your iPhone and looking for the 'Freq Band Indicator.' This helps you know if the booster will work for your phone.
8.  Can I upgrade parts of the booster kit? - Yes! You can upgrade parts of the booster kit, like the external cables or antennas, if you need better performance. This can help improve the signal even more based on your specific situation.
9.  Is there a protector for the booster equipment? - Yes, you can get a Lightning Surge Protector. This device protects your booster equipment from power surges caused by lightning, ensuring it stays safe and works well even during storms.
10.  How many devices can connect to the booster at once? - The booster can support up to 10 devices connected at the same time. This means multiple people in your home or office can enjoy improved mobile signal and internet access.
