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.

What is a 3G mobile signal booster? - A 3G mobile signal booster is a device that strengthens mobile phone signals inside your home or office. It collects weak signals from outside and boosts them to improve your connection. This can help you make clearer calls, use data faster, and even extend your phone's battery life! 2. How does the signal booster work? - The signal booster works by grabbing a weak signal from the outside and amplifying it. It has two antennas – one outside to catch the signal and one inside to spread the boosted signal throughout your space. This helps create a stronger and more reliable connection for your phone. 3. What mobile networks are supported? - The booster is designed to work with Spark, Skinny mobile, and Slingshot in New Zealand. It enhances 3G signals on both 850MHz and 2100MHz frequencies, which are commonly used by these mobile networks. 4. How much area can the booster cover? - The mobile signal booster can cover an area of up to 100 square meters, which is a great fit for small homes or offices. If you live in a bigger space, you might need to consider additional equipment! 5. Can the booster create a signal? - No, the signal booster cannot create a signal; it can only amplify one that already exists. So, if there's no signal outside, the booster won't be able to help. 6. Is it easy to install the booster? - Yes! The signal booster kit comes complete with all the items you need, including antennas and cables, and it’s fairly easy to install. Just follow the included instructions, and you should be up and running in no time! 7. What if I need to cover a larger area? - If the standard 10-meter external cable that comes with the booster isn't long enough for your area, you can easily upgrade to a longer cable. This way, you can position the outdoor antenna for the best signal! 8. What if I have weak signal bars indoors? - If you notice your mobile phone shows only 1 or 2 signal bars inside, consider upgrading to a higher-gain Yagi antenna. This antenna helps improve signal performance significantly. 9. How do I know if I need a surge protector? - A surge protector can be helpful if you are in an area with frequent lightning storms. It protects your equipment from high amperage surges that can happen during strikes. If you want to keep your investment safe, consider adding it! 10. Can multiple people use the booster at once? - Yes! The 3G mobile signal booster can support up to 10 users simultaneously, making it great for families or small offices where multiple devices need a strong signal.
