NOTE: These instructions will walk you through a “soft” install process to find the optimal locations for the inside and outside antennas, then through the process of the permanent installation. 1 to 2 hours 2 people (a person to help with antenna calibration) Ladder Drill (if routing cable through wall) 1”-3” diameter existing pole for mounting Outdoor Antenna (Pole Mount can be purchased separately if needed) Recommended: Power Strip with surge protection 2 Step 1: Inside Antenna Placement Choose right position for the indoor antenna • 1 feet away from any other metallic objects • 3 feet away from any windows Place the Inside Antenna where you need the greatest signal boost and place Booster in your desired location. NOTE: Do not connect booster to power until the system is fully installed. 3 (STEP 1 cont.) Booster Placement Mount the booster • Choose a ventilated and dry place • Keep away from heat • Don't cover booster Booster will about 30 degrees Fahrenheit higher than the ambient temperature, which is a normal phenomenon. 4 Step 2: Mount & Point Outside Antenna Toward Nearest Cell Tower Pole mounting and wall mounting options are included. The pole mounting option is preferred because it will be easier to adjust to the direction of the cell tower. Attach the Mount to the Outside Antenna and use the Bracket Clamps to attach the Antenna to a pole or exhaust pipe. Make sure that the outside unit is mounted at least 3 feet away from any windows. Outdoor antenna must be installed over the roof line. NOTE: Mounting on existing roof exhaust pipe would be a good time-saver option. Watch out for power lines. 5 ①② ③ Point the Outside Antenna toward the nearest cell phone tower. To find the nearest tower, use an app such as 'Open Signal'. This is the most critical step of the installation process because it will determine the overall performance of the booster system. 6 NOTE: The Outside Antenna must be at least 40 feet (12 meters) Straight line distance or 30 feet (9 meters) horizontal 20 feet (6 meters) vertical from the Inside Antenna for best performance. Keep enough distance between outside and inside antenna The greater the separation between the Inside and Outside Antennas, the better performance you will get from the booster. 7 Select the optimal mounting location for the outside antenna 8 After identifying the area of strongest signal, choose the surface where you will mount your outside antenna. 1. The location should allow for sufficient separation between the outside antenna and inside antenna. 2. In order to better receive external signals, the outside antenna is best installed in a higher position on the house, but please pay attention to lightning protection. Antenna mutual position 9 The outside antenna should be oriented in a way that it does not “face” the inside antenna. Caution: Do not aim an outside antenna towards inside antenna. Caution: The inside antenna cannot face the outside antenna. Step 3: Route & Connect Outside Antenna To Booster Connect the white 3D-FB Cable to Outside Antenna and route cable into the home, secure the cable near the antenna. All connections should be finger tightened only. Route cable to the Booster and connect to the port labeled 'OUTSIDE'. 10 Step 3: Route & Connect Inside Antenna To Booster Connect the Inside Antenna to the 'INSIDE' port on the booster. 11 (STEP 3‐A cont.) 12 Fasten bracket to back of Inside Antenna Secure bracket to wall Drill holes Tap anchors in Mounting Inside Antenna on wall bracket sideview Wall Mounting Option Step 4: Power Up The Booster & Optimize The System Plug in the Power Supply and connect it to the nearest power outlet. NOTE: We strongly recommend using a power strip with surge protection.

Test Specification Test Requirement: FCC Part2 Section 1051; FCC Rules Part 27 Subpart C, Section 27.53 Test Method: KDB 935210 D03 Signal Booster Measurements v04r04 Limit: -13 dBm； For equipment operating in the frequency bands 746-7 56 MHz and 777-787 MHz, The power of any unwanted emissions in any 6.25 kHz bandwidth for all frequencies between 763-775 MHz and 793-806 MHz shall be attenuated below the transmitter power, P (dBW), by at least: (i) 76 + 10 log10 p (watts), dB, for base and fixed equipment, and (ii) 65 + 10 log10 p (watts), dB, for mobile and portable equipment. Test Setup: Test Procedure: a) Connect the EUT to the test equipment as shown in Set-Up. Begin with the uplink output connected to the spectrum analyzer. b) Configure the signal generator for AWGN with a 99% occupied bandwidth of 4.1 MHz operation with a center frequency corresponding to the center of the CMRS band under test. c) Set the signal generator amplitude to the level determined in the power measurement procedure in Maximum power. d) Turn on the signal generator RF output and measure the spurious emission power levels with an appropriate measurement instrument as follows. e) Set RBW = measurement bandwidth specified in the applicable rule section for the operational frequency band under consideration (see Annex A for relevant cross-references). Note that many of the individual rule sections permit the use of a narrower RBW (typically ≥ 1% of the emission bandwidth) to enhance measurement accuracy, but the result must then be integrated over the specified measurement bandwidth. f) Set VBW = 3 X RBW. g) Select the power averaging (RMS) detector. (See above note regarding the use of a peak detector for preliminary measurements.) h) Sweep time = auto-couple. i) Set the analyzer start frequency to the lowest radio frequency signal generated in the equipment, without going below 9 kHz, and the stop frequency to the lower band/block edge frequency minus 100 kHz or 1 MHz, as specified in the applicable rule part. Note that the number of measurement points in each sweep must be ≥ (2 X span/RBW) which may require that the measurement range defined by the start and stop frequencies above be subdivided, depending on the available number of measurement points provided by the spectrum analyzer. Trace average at least 10 traces in power averaging (i.e., RMS) mode.

Note that the number of measurement points in each sweep must be ≥ (2 X span/RBW) which may require that the measurement range defined by the start and stop frequencies above be subdivided, depending on the available number of measurement points provided by the spectrum analyzer. l) Use the peak marker function to identify the highest amplitude level over each of the measured frequency ranges. Record the frequency and amplitude and capture a Test Plots for inclusion in the test report. m) Repeat steps b) through l) for each supported frequency band of operation. Test Result: PASS 5.5.2.

Radiation Spurious Emission 6.1.1. Test Specification Test Requirement: FCC Part2 Section 2.1053 Test Method: KDB935210 D03 Signal booster Measurements v04r04 Limit: -13dBm; For equipment operating in the frequency bands 746-7 56 MHz and 777-787 MHz, The e.i.r.p. in the band 1559-1610 MHz shall not exceed -70 dBW/MHz for wideband signal and -80 dBW for discrete emission with bandwidth less than 700 Hz. Test setup: Test Procedure: a) Place the EUT on an OATS or semi-anechoic chamber turntable 3 m from the receiving antenna.15 b) Connect the EUT to the test equipment as shown in Figure 10 beginning with the uplink output (donor) port. c) Set the signal generator to produce a CW signal with the frequency set to the center of the operational band under test, and the power level set at PIN as determined from measurement results per 7.2. d) Measure the radiated spurious emissions from the EUT from the lowest to the highest frequencies as specified in § 2.1057. Maximize the radiated emissions by using the procedures described in ANSI C63.4. e) Capture the peak emissions Test Plotss using a peak detector with Max-Hold for inclusion in the test report. Tabular data is acceptable in lieu of spectrum analyzer Test Plotss. f) Repeat 7.12c) through 7.12e) for all uplink and downlink operational bands.
