The optimal area would be on a wall located near a power outlet. It should be mounted in an easily accessible area so it’s easy to perform general maintenance with the coaxial cable connections, dip switch settings and power adaptor. Make sure all cables and antennas are securely connected before commissioning the system. POWER UP YOUR CELLULAR BOOSTER Once all the next page precautions have been taken, power on the cellular booster. The LED indicator marked power should light up green. - Page 20 Contact Tech Support at 1.800.215.7015 or email at support@unidencellular.com IMPORTANT: Verify that you have left at least 20 feet of vertical separation space between the indoor and outdoor antennas. Never point the front of the yagi signal (outdoor) antenna towards the inside of the distribution (indoor) antenna. Verify that the supplied coaxial cables from both the signal (outdoor) antenna and the distribution (indoor) antenna are properly connected to the cellular booster before powering it up. Carefully plug in the supplied 110-volt power adaptor into the back of the cellular booster where it is marked ‘power’ and connect the other end to a power outlet. WARNING! Using a power supply that is not included in your kit could damage your equipment and void your warranty. CHECK THE CELLULAR BOOSTER LED ALARM LIGHTS Your cellular booster comes equipped with electronic sensors designed to identify cellular signal overload or oscillation which can hinder signal- boosting performance. Your cellular booster is specially designed to automatically decrease gain to compensate for these circumstances. The device also has a feature to automatically shut down in case of excessive oscillation.

Page 21: Check The Cellular Booster Status
Contact Tech Support at 1.800.215.7015 or email at support@unidencellular.com Improper equipment installation and unusable signal quality can cause oscillation, this is why it is important to fully understand the LED alarm lights on your booster, as they will help you identify and solve any potential issues. The color of the LED indicates the status of the booster system. TWO TYPES OF LED INDICATORS 1. POWER INDICATOR: Shows whether the cellular booster is on or off. 2. SIGNAL INDICATOR: The color of the LED indicates the status of the booster for each of these frequencies. There is one alarm LED light for each of the cellular frequency ranges (850 MHz,1900 MHz & 1700/2100 MHz). CHECKING THE SIGNAL STATUS The signal indicator’s LED will notify you as to whether your cellular booster is experiencing any oscillation or feedback. The purpose of these LED’s is to allow you to fine tune your booster to achieve optimal signal quality. The bullet list below indicates what measure should be taken based on the color of the LED alarm lights. Green: indicates the system is working properly.. Orange: the system is experiencing slight oscillation and requires slight adjustment. See next page for adjustment procedures. Red: the system is experiencing severe oscillation. Turn the unit off and make adjustments as outlined on the next page. -

Contact Tech Support at 1.800.215.7015 or email at support@unidencellular.com ADJUSTING THE MANUAL GAIN CONTROL: & The manual gain control (MGC) adjusts the overall amplification level (gain) of the booster. The Manual Gain Control is used to resolve the issue of oscillation without the need of readjusting your antennas, in most cases. The MGC allows you to easily reduce the amount of gain (amplification) the booster is emitting. This is done with a set of dip switches on the side of the booster. There are a series of dip switches to adjust the uplink and another set to adjust the downlink. There are two sets of dip switches, one is labeled “1900MHz” and the other labeled “850 MHz”. Each set is divided between the downlink and the uplink. The dip switches, when put into the “ON” position will reduce the gain of the booster for the designated frequency and transmission direction. When the LED alarms indicate oscillation (turns orange, red or off) you need to reduce the gain of the downlink and the uplink for the appropriate frequency. Do this gradually in order to determine the ideal level. ADJUSTING THE UPLINK Please follow these procedures for each frequency. If the alarm LED turns off immediately after commissioning the system, the signal on the uplink is likely too strong. Take measures to reduce the uplink gain. Continue to increase the gain reduction until the alarm light changes to green. ADJUSTING THE DOWNLINK Once you have fine-tuned the uplink signal, it is time to adjust the downlink. If the alarm LED is green you are all set. If the alarm LED is orange, you will only need to reduce the gain slightly.

There are a series of dip switches to adjust the uplink and another set to adjust the downlink. There are see three sets of 8 dip switches,they are labeled “CDMA” , “PCS” and “AWS”. Each set is divided between the downlink and the uplink. The dip switches, when put into the “ON” position will reduce the gain of the booster for the designated frequency and transmission direction. When the LED alarms indicate oscillation (turns orange, red or off) you need to reduce the gain of the downlink and the uplink for the appropriate frequency. Do this gradually in order to determine the ideal level. ADJUSTING THE UPLINK Please follow these procedures for each frequency. If the alarm LED turns off immediately after commissioning the system, the signal on the uplink is likely too strong. Take measures to reduce the uplink gain. Continue to increase the gain reduction until the alarm light changes to green. ADJUSTING THE DOWNLINK Once you have fine-tuned the uplink signal, it is time to adjust the downlink. If the alarm LED is green you are all set. If the alarm LED is orange, you will only need to reduce the gain slightly. If the alarm LED is red, you will need to greatly reduce the gain. As you implement the gain reductions, the LED alarms should change from red or orange to green. - Page 37 Contact Tech Support at 1.800.215.7015 or email at support@unidencellular.com MGC DIP SWITCH CONTROL FOR The Uniden U70 4G CPA allows you to manually attenuate the db gain of the device in increments of 1, 2, 4 and 8 db with a maximum of 15 db.

Contact Tech Support at 1.800.215.7015 or email at support@unidencellular.com TROUBLESHOOTING The LED alarm lights represent the status of the booster on each frequency. When the lights are green the device is operating normally meaning that it is not experiencing any oscillation (feedback) and it is boosting the signal at maximum power. When the LED lights begin to change color from green to orange to red, it means that particular frequency is experiencing some oscillation (feedback). If the oscillation is excessive the booster will shut down for that particular frequency. The booster will still work for the other frequency on a multi-band booster. Oscillation is caused when the indoor (distribution) antenna sends a signal back into the outdoor (signal) antenna. Similar to a PA system, when the microphone gets too close to the speaker it causes feedback. This will occur if your antennas are too close together, or the indoor antenna is pointed at the outdoor antenna. Make sure you have adequate separation and some type of shielding between the antennas (usually your roof or a cement wall is good enough). IMPORTANT NOTES The 2 most important things to look for when setting up your system is: A good input signal (the best you can find) Isolating the outdoor (signal) antenna from the indoor (distribution) antennas so they do not feedback into each other. - Page 39 Contact Tech Support at 1.800.215.7015 or email at support@unidencellular.com By capturing the best input signal you will be able to enjoy the maximum coverage and best quality signal inside where your distribution antennas are located. The better the input signal, the better the output signal. In order to find the best input signal, you want to place your outdoor (signal) antenna as high as possible with the least amount of obstruction between the antenna and the cellular base tower. A clear line of site is ideal. Isolating the signal from the antennas is done by ensuring that the antennas are not pointing to each other and by having enough distance or barrier shielding in between them. The signals travel like rays of sunlight, a directional antenna will send the signal in the direction that it is pointing. An omni directional antenna will send the signal in every direction around it. So depending on your equipment its important to be sure that your distribution antenna (indoor) is not sending the signal back into the outdoor (signal) antenna. THINGS TO CHECK WHEN EXPERIENCING WEAK CELLULAR SIGNAL Ensure the signal antenna (outdoor) is pointing in the correct direction and is capturing adequate signal for the booster.

Contact Tech Support 7 days a week at 1.800.215.7015 or email at support@unidencellularbooster.com FREQUENTLY ASKED QUESTIONS WHY ARE THE LED LIGHTS TURNING ORANGE, RED OR SHUTTING OFF? There are certain cases where your system could be experiencing oscillation. This can be attributed to either the quality of your input signal or having your signal (outdoor) antenna and distribution (indoor) antenna too close together. Please review the following guidelines to help resolve this issue: 1. Adjust the direction of the signal (outdoor) antenna. If the system is receiving a very high input signal, you can point your signal (outdoor) antenna away from the cellular tower to reduce the strength of the input signal and therefore, reduce the oscillation. Alternatively if your system is receiving a very poor quality signal (weak and unusable signal), you can point your signal (outdoor) antenna more directly towards the cellular tower to increase the strength of the input signal. Sometimes this may require completely repositioning the antenna to a location where you can achieve a line of site to the tower. 2. Increase the separation between the signal (outdoor) antenna and the distribution (indoor) antenna. This can be achieved by increasing the distance between the two antennas or by placing barriers between them, such as moving the distribution (indoor) antenna to an adjacent room where there would be an additional wall separating them from the signal (outdoor) antenna. 3. Manual Gain Control. Adjust the gain with the manual gain control function using the dip switches on the side of the booster. See page 22 for more details. - Page 41 Contact Tech Support 7 days a week at 1.800.215.7015 or email at support@unidencellularbooster.com Contact Tech Support at 1.800.215.7015 or email at support@unidencellular.com I INSTALLED THE BOOSTER AND MY SIGNAL STRENGTH IS STILL WEAK In order to correct a weak signal; essentially you have the options of: • Adjust the aim of the signal (outdoor) antenna or replace it with a higher gain antenna. • Move the distribution (indoor) antenna. • Increase the number of distribution (indoor) antennas. • Reducing the attenuation values you chose when setting the manual gain control. I CANNOT MAINTAIN CALLS, MY SIGNAL STRENGTH FLUCTUATES If you find the booster is working but drops calls or delivers fluctuating signal levels, the most likely cause is oscillation between the signal and distribution antenna(s).
- Page 42 Contact Tech Support at 1.800.215.7015 or email at support@unidencellular.com MY LED’S ARE ALL GREEN BUT MY SIGNAL IS STILL WEAK - MY COVERAGE IS POOR If you receive a signal where you did not previously... or, if the radius of the service area covered is small...and your LED’s are all green... the booster is working properly but for some reason the signal is not very strong. This can be due to weak input signal. • Adjust your signal (outdoor) antenna to point more accurately at the cellular tower in order to increase the input signal. • Check the coaxial cable to ensure there are not any creases or cuts in it. Perhaps the cable was damaged during installation. WHY ISN’T MY CELL PHONE INDICATING MORE SIGNAL WITH MORE BARS? You may not always observe more bars on your signal meter because of the signal spreading out from the antenna. If your phone has a db meter, 3db is a significant...
