Ensure adequate separation between the planned locations of the inside and outside antenna at least 25 ft (see diagram Antenna Separation on page 7). For kits that use directional antennas (outside or inside), the directional antenna(s) should be oriented in a way that they do not face the other antenna (see Aiming Directional Antennas Diagram). Ensure sufficient cable length between the outside antenna location and booster location. The length of the provided cable is 50 ft. Installation Overview Step 1. Find the outside area with the strongest signal. Step 2. Install the outside antenna and outside amp in the location identified in step 1. Step 3. Install the Inside antenna and inside in where signal is needed. Step 4. Connect power source and turn on. Step 5. Configure gain settings if needed. INSTALLATION Step 1. Find the Area With the Strongest Signal Using your phone, identify the outside location with the strongest signal for placement of your outside antenna. Generally, this is found above the roofline on the side facing your nearest cell tower and as high as possible where the antenna can see your cell tower. To find the location of your carriers closest cell tower, go to www.antennasearch.com. The coverage area that the booster provides is directly related to the strength of incoming signal received by the outdoor antenna. Mounting the outside antenna where the signal is the strongest will provide the best results. Please note, if signal is extremely weak where the outside antenna is installed, indoor coverage will be limited. Bars are not always a reliable measure of signal. The best way to confirm signal coverage is the ability to place and hold a call. More detailed measurements can be taken by reading your phones signal in decibels(dB). Decibels are measured in the Signal Strength B d 0 0 1

Install the Outside Yagi Antenna and Outside Amplifier Before installing a Yagi, or directional antenna, note that the antenna should be mounted on a pole or pipe (not provided), at the highest possible location above the roofline at least 25 ft above the indoor antenna aimed in the direction of your nearest cell tower. To find the location of your carriers closest cell tower, go to www.antennasearch.com. Ensure that the mounting area has at least a 3 ft radius clear of obstructions, other radiating elements and metal objects such as pipes or metal siding and orient the antenna with the drip hole at the bottom. Washer U-bolt Nut Bracket Warning: Do not collocate antennas or operate the outdoor antenna with any other antenna or signal booster. Drip Hole RG6 Cable Yagi Antenna Assembly 7 SureCall, Inc | 1-888-365-6283 | support@surecall.com | www.surecall.com Once you have identified your install location, assemble the u-bolt, bracket, nuts and washers onto a pole (available separately) as shown in the illustration. Keep the connections loose enough to allow the antenna to rotate until the optimum direction is found. Next assemble the outside amplifier to provided bracket as shown below and secure to in the same location. Connect the Yagi antenna cable connector to the outside amplifier. Outside Antenna Mounting Pole not included Outside System assembled OK Aiming Directional Antennas 8 Caution: Do Not aim a directional antenna towards another antenna SureCall, Inc | 1-888-365-6283 | support@surecall.com | www.surecall.com SureCall, Inc | 1-888-365-6283 | support@surecall.com | www.surecall.com Step 3. Install the Inside Amp and Inside Antenna. Choose a location for the booster and inside antenna that is near a working outlet and at least 25 Ft from the outside antenna. Consider the below factors affecting booster performance. 1. Signal strength at the location of the outside antenna. 2. Interior building materials between the inside antenna and your mobile device. 3. Distance between the outside antenna and inside antenna (minimum 25 ft. separation) Panel Antenna Fusion4Home Max inside host amplifier and power supply Note: This booster should not be used near open fire or flame. Storage and transportation: Store and place in non-extreme room-temperature and dry environment. Panel Antenna SureCalls Inside panel antennas are directional with a 120 reach. They should be mounted facing the area signal is needed and away from the outdoor antenna (See Aiming Directional Antennas on page 8). Mount on a vertical surface that is the approximate height of normal cell phone use. The antenna may be concealed behind a wall provided there are no materials that could obstruct signals. Besides the antenna itself, parts include mounting equipment for a flat horizontal surface. 1. Using plate, mark position of desired screw placement. 2. Screw mounting plate into place with the slide panel protruding towards you. 3. Slide antenna securely onto mounting plate. 4. Connect antenna to one end of the SC-240 cable and run to location of your host amp 5. Place the host amp on a flat surface or mounted to a wall and connect the remaining end of the SC-240 cable to booster port marked INSIDE. Anchors /

Screws Mounting Plate 9 SureCall, Inc | 1-888-365-6283 | support@surecall.com | www.surecall.com Place the Inside Host To install the booster to a wall, select a location that is near a working AC outlet. Use the supplied screws or appropriate screws for surface of mounting location and drill through screw tab holes on booster (see Booster Diagram illustration) and mount the booster to a wall. Next, connect the outside and inside components by routing the outside cable from the outside amplifier indoors and connect to the booster port marked OUTSIDE. Step 4: Connect to Power and Turn On Connect the AC power cord to the booster and plug into a 110V AC power outlet. Once the booster has been completely assembled, turn the boosters power switch to ON. Note: If the Power LED does not turn ON or the Alert LEDs continue to flash, see the Troubleshooting on page 11 section. Note: This booster is rated for 5-15V input voltage. DO NOT use the booster with a higher voltage power supply. This can damage the booster, cause personal injury, and void your warranty. 44 OFF 44 OFF 45 OFF 52 OFF 51 OFF 54 64 54 64 55 65 62 72 61 71 N connector to inside antenna Power Switch Connector to Inside Antenna Power Jack Screw tab holes for optional wall mounting F connector to outside antenna Booster Diagram 10 SureCall, Inc | 1-888-365-6283 | support@surecall.com | www.surecall.com SureCall, Inc | 1-888-365-6283 | support@surecall.com | www.surecall.com Step 5: Configure Gain Settings If Needed Place a call in the room where the inside antenna is located to confirm that your phone is receiving a boosted signal. Note: Bars are not always a reliable measure of signal. The best way to confirm signal coverage is the ability to place and hold a call. Only the presence of a RED/YELLOW flash indicates the presence of an unresolved issue. Important: The booster gain dials should remain at maximum level and only reduced if other recommended actions do not resolve the issue. IF YOU WANT TO IMPROVE PERFORMANCE Antenna Isolation The Fusion4Home Max automatically reduces gain (coverage performance) because of insufficient RF Separation between the inside and outside antennas. Review strategies to improve RF isolation between the inside and outside antennas. Note, in smaller wood constructed homes some reduction in gain (slow YELLOW flash) is considered normal operation. Consider the following options to resolve issues with inadequate antenna isolation. 1. Verify that a minimum distance of 25 vertical feet has been achieved. Separation up to 40 - 50 ft may be needed, however, especially where vertical separation is not possible. 2. Check for sources of interference such as, cellular modems or hotspots. 3. Verify neither antenna is placed near a window. 4. Ensure that the antennas are aimed away from one another.
