It is recommended that you read through all of the installation steps and familiarize yourself with the product. Read the instructions and visualize where you want to place the components before mounting any equipment. If you do not understand the instructions in full, please contact Wilson Technical Support at 866-294-1660. Reasons for Weak Cellular Signals Anyone who uses a cell phone or cellular data card knows the frustration of not being able to connect to or maintain a strong cellular signal. When this occurs, it’s generally due to one of two reasons: 1. Location of the Nearest Cell Tower – Cell towers are situated to provide broad coverage; however, there are many areas in which signal strength may be reduced by topographic features or by local government restrictions on the height or placement of the towers themselves. Rural areas generally have fewer cell towers than urban regions. 2. Natural and Man-made Obstructions – Signal strength can also be negatively affected by trees, hills, buildings and other obstructions. You may be relatively close to a cell tower but still unable to make a call. This often occurs in homes, offices and other buildings in which stucco, concrete or metal walls block the signal. Whether you’re too far from the nearest cell tower to obtain a usable signal or you’re located in an area or building where the signal is obstructed, the Wilson SIGNALBOOST™ DT can help you get connected and stay connected! How to Check Your Outside Signal Strength Before you install your SIGNALBOOST™ DT, it is very important that you determine the location of the best available cellular signal outside your building. This will affect where you place the cradle antenna and will help you get the best performance from your system. Your cell phone can help you find the strongest outside signal, using any or all of the following methods: 1. Place calls from several locations outside your building and note where you get the best reception. 2. Check the bar indicator on your cell phone display and note where the signal appears to be the strongest. (Note: cell phone bars are only an approximation of signal strength and vary from phone to phone.) 3. Using the test mode on your cell phone, move around the outside of your building and determine the location of the strongest signal. (For assistance with the test mode on your particular phone, visit the Technical Support section of our website: www.wilsonelectronics.com or call our Technical Support Department at 866-294-1660 or 435-673-5021.) Once you have determined where the outside signal is strongest, you should plan to install the cradle antenna in that general area, either inside or outside. (See the following section for alternative installation options.) SIGNALBOOST™ DT Installation Instructions Installation Options - Cradle Antenna The SIGNALBOOST™ DT comes with all necessary parts for installation of the cradle antenna in three alternative locations: • Inside on a window (suction cups or double-sided adhesive strip) • Outside on a wall (screws, washers and anchors) • Outside on a pole (bracket, nuts and washers) The best location for your particular application depends primarily on outside signal strength (see page 4). For example, if your strongest signal is obtained on the north side of the building and a suitable window exists in that area, you may want to mount the cradle antenna inside on the glass (see page 6). If you find the strongest signal in an area with no window, an outside wall mount may be a better choice (see page 7). Or, if your particular application allows for the installation of the antenna on a roof or balcony to obtain the strongest signal, mounting the cradle outside on a pole (not included) may be your best option (see page 8). IMPORTANT! Depending on your particular installation, the antenna must be positioned in the cradle correctly. The side with the Wilson label should face in the direction of the cell tower. Note: The amplifier itself is designed to sit on a desk, table or shelf; however, it may also be mounted on a wall with the included triangular bracket if you so desire (see page 9). In all cases, you will want to insure a separation of at least 20 feet between the cradle antenna and the amplifier. The SIGNALBOOST™ DT comes with 50 feet of low-loss coaxial cable. Additional lengths of cable and the necessary connectors are available through your Wilson dealer, but keep in mind that using longer cable will result in some signal loss.

Ensure that the distance between the amplifier and the cell phone or cellular data card does not exceed 4 feet. Min. 20 feet 2. Important: Ensure that any other cell phones and cellular data cards are turned off unless they are at least twice the distance from the amplifier than the desired unit. 3. Ensure that the distance between the on-board antenna and the cradle antenna is a minimum of 20 feet. If you are using a different antenna configuration, see the separation guidelines for your specific antennas or call Wilson’s Technical Support department at 866-294-1660 or 435-673-5021. 4. Ensure that the coax cable is attached to the amplifier and the cradle antenna before powering up the amplifier. 5. Plug the power supply into the amplifier input marked “Power” (carefully, to avoid damaging the center pin) and then into a wall outlet. Warning: Verify that the on-board antenna is attached and that the cable from the cradle antenna is connected before powering up the amplifier. Warning: Use only the power supply provided in this package. Use of a non-Wilson product may damage your equipment. Understanding the Indicator Light GREEN: AMBER: RED: SIGNALBOOST™ DT Installation Instructions The indicator light on the top of the amplifier will be GREEN when the unit is powered up and working properly. If the indicator light is AMBER, this indicates that the cell phone or data card may be too close to the amplifier and the amplifier has automatically reduced its gain. Move farther from the amplifier when making a call so that the light is green. If the indicator light is RED, the amplifier has detected oscillation. Increase the separation between the on-board antenna and the cradle antenna (or whatever two antennas you may be using). Remove and reinsert the power cable to reset the amplifier. If the light remains red, repeat the antenna separation/power reset procedure until the light is green. 10 Warnings and Recommendations Warning: Connecting the amplifier directly to the cell phone with use of an adapter will damage the cell phone. Warning: Attach the on-board antenna and connect the cradle antenna before powering up the amplifier. Warning: Use only the power supply provided in this package. Use of a non-Wilson product may damage your equipment. Warning: RF Safety: A minimum separation distance of at least 8 inches must be maintained between the antennas supplied with this amplifier and all persons. A different antenna may be used in place of the on-board antenna, provided that its gain does not exceed 15 dBi and it is separated by at least 8 inches form all persons. Antennas outside of the building may have gains as high as 15 dBi, provided that a separation distance of at least 30 inches is maintained between the antennas and all persons. Use of antennas with higher than the above maximum gains and/or closer to people than the specified minimum distance is in violation of FCC regulations for which the offender is fully liable. Frequently Asked Questions What kind of improvement in cell phone performance can I expect with the SIGNALBOOST™ DT? The SIGNALBOOST™ DT’s performance will depend somewhat on the strength of the cellular signal outside your home or building. However, if you install the SIGNALBOOST™ DT in accordance with the instructions in this guide, you can expect a significant improvement in your ability to use your cell phone or cellular data card indoors. Where should I install my SIGNALBOOST™ DT to get the best coverage? You should install the amplifier in the area where you most need an improved signal. The farther you are from the amplifier, the less improvement you will experience. It is also important to install the cradle antenna in a location where you have the strongest outside signal (see page 4). Also keep in mind the distance between the amplifier and the cradle antenna. You’ll need at least 20 feet of separation to prevent the start of oscillation, but you’ll probably want to stay within the 50-foot length of the coax cable. (Additional cable and the necessary connectors are available from your Wilson dealer, but using more cable will result in some signal loss.) Instead of placing the amplifier on a desk or table, I’d rather attach it to a wall – will it still work OK? Yes! Your SIGNALBOOST™ DT comes with a triangular wall bracket that allows you to mount the amplifier on a wall. Just be sure that the on-board antenna is positioned vertically and not at a right angle to the wall (see page 9). What color should the indicator light be showing? Once the amplifier is powered up, the indicator light should be green during normal operation. The amplifier indicator light is amber – what does that mean? An amber light indicates that the amplifier has reduced its gain because the cell phone or data card is too close to it. Move farther away from the amplifier when making a call or using your data card. The amplifier light is red – what does that mean? A red light indicates oscillation between the on-board antenna and the cradle antenna. Increase the separation between the amplifier and the cradle antenna, then remove and reinsert the power cable to reset the amplifier. If the light remains red, repeat this procedure until the light is green. 11 SIGNALBOOST™ DT Installation Instructions I have a Nextel phone – will the SIGNALBOOST™ DT boost that signal? The SIGNALBOOST™ DT is designed to work with both the Cellular (800 MHz) and PCS (1900 MHz) bands, but not the iDEN/Nextel frequency. Wilson offers specific amplifiers for iDEN/Nextel users. Visit www.wilsonelectronics.com for details. Can I use my own cable for my installation? The low-loss RG6 cable included with your product has been specifically selected for the SIGNALBOOST™ DT. Use of another type or longer length of cable will likely degrade the system’s performance. There are frequently several people using cell phones in my building at the same time – will the SIGNALBOOST™ DT improve the signal for all of them? Absolutely! The SIGNALBOOST™ DT is designed to support multiple users simultaneously. I have questions about my installation – where can I get some help? Wilson’s Technical Support representatives are just a phone call or email away. Call 866-294-1660 or 435-673-5021, or send an email to tech@wilsonelectronics.com.

Nominal gain is the maximum gain at any frequency in the passband. 2. Nominal bandwidth is the difference between two frequencies that are adjacent to the passband where the amplification is 20 dB lower than the passband amplification. One of the frequencies is lower than the passband and the other is higher. 3. The Manufacturer’s rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. 4. The maximum power for 2 or more simultaneous signals will be reduced by 6 dB every time the number of signals is doubled. Part #104027 AIGR SBDT 007 - 07.11.07
