YETCELFI-RS225CUAAT&T Provider Specific Consumer Signal Booster

Step 1 Find the spot with the best 3G coverage: The first step in setting up your Cel-Fi system is to find the spot in your home or office that has the best 3G coverage by using your phone (3G icon must be displayed). This is typically by a window, and if you are in a multi-story building, upstairs windows are usually better than downstairs windows. Step 2 Plug in the Window Unit: Take the Window Unit and one power supply out of the box (both power supplies are identical, so you can use either one). Plug the Window Unit into an easily accessible outlet. Check to make sure that you can see at least 1 “Bar” on the display in the center of the device. If you do not see at least 1 bar, try a different location. CEL - FIRS 2duaL Band Quick Start Guide 3G WINDOW UNIT WIndOW unIT COVERaGE unIT Congratulations on your new indoor signal solution. This Cel-Fi system is designed to provide you with significant improvements in coverage as well as 3G data rates. Setting up the system is extremely simple and consists of placing and plugging in two components; a Window unit and a Coverage unit. By spending just a few minutes using the instructions in this guide, you can optimize the installation and get the very most from your new Cel-Fi System. If you have any trouble during setup, please use the trouble shooting steps included in this guide. In the package you will find: • Window unit • Coverage unit • Two Power adapters This is a COnSumER device. BEFORE uSE, you muST REGISTER ThIS dEVICE with your wireless provider and have your provider’s consent. most wireless providers consent to the use of signal boosters. Some providers may not consent to the use of this device on their network. If you are unsure, contact your provider. You muST operate this device with approved antennas and cables as specified by the manufacturer. antennas muST be installed at least 20 cm (8 inches) from any person. You muST cease operating this device immediately if requested by the FCC or a licensed wireless service provider. WaRnInG. E911 location information may not be provided or may be inaccurate for calls served by using this device. When used with any mobile device utilizing the 1710-1755 mhz band, the FCC limits booster equipment placement to a maximum of 10 meters above ground level. Installation of this equipment which does not comply with federal requirements may subject the owner to FCC enforcement action. nOT FOR RESaLE. Changes or modifications not expressly approved by nextivity, Inc. could void the user’s authority to operate the equipment. nOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. however, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help Cel-Fi is a registered trademark of nextivity, Inc.

Step 4 Place the Coverage Unit: move to a location in your home where you need to have improved coverage. Plug the Coverage Unit into an easily accessible outlet. Wait until the numeric display stops cycling. This could take several minutes. at this point you should see a green icon indicating that the unit is working properly. It is possible to place the Coverage Unit so far away that it cannot communicate with the Window Unit. If this happens, a red icon will illuminate indicating that you need to move the Coverage Unit closer to the Window Unit. TOO CLOSE a zero on the numeric display indicates that the Coverage Unit needs to be moved farther away from the Window Unit. GOOD This green icon indicates that the Coverage Unit is functioning normally. TOO FAR This red icon indicates that the Coverage Unit needs to be moved closer to the Window Unit. Step 3 Optimize the Window Unit Placement: The number of bars you can see on the Window Unit make a significant difference in the operation of the Cel-Fi system. Try moving the Window Unit to a couple of different spots to see if you can get a better signal; the more bars the better. Step 5 Optimize The Coverage Unit Placement: The farther away you place the Coverage Unit from the Window Unit the better the coverage in your home, so put the Coverage Unit as far away from the Window Unit as possible. The number shown on the side of the display gives you an indication as to the quality of the placement. Test two or three locations and for best results; try and get an 8 or 9 on the display.

MPE Calculation Results: 5470-5725MHz In the case the equipment meets compliance by MPE Calculations the product is approved for use under mobile conditions without further testing under the condition that any additional collocation or simultaneous transmission requirements (including necessary separation distances) have been met. It is assumed that the manufacturer shall design the equipment such that the minimum separation distance of 20cm (or greater, as listed above) is met or that the manufacturer provides a protection guide (or installation instructions) to the end user such that the antenna(s) may be installed in accordance with the manufacturer’s instructions in such a manor to maintain the minimum separation distance. The Absorption and distribution of Electromagnetic energy in the body is a very complex phenomena that depends on the mass, shape and physiological condition of the body; the orientation of the body with respect to the fields; and, the electrical properties of the body and the environment. Variables that may play a substantial role in possible biological effects are those that characterize the environment (including but not limited to: ambient temperature, air velocity, relative humidity and body insulation); and those that characterize the individual (including but not limited to: age, gender, activity level and existing debilitation or disease). Because innumerable factors may interact to determine specific biological effects of exposure to electromagnetic fields, any protection guide should consider both intended and unintended operational environments and provide guidance for installation and use of the product such that proper separation distances can be maintained.
