3. The amplifier should be situated so that its location does not interfere with its proper ventilation. 4. This amplifier should be connected to a power supply of the type described in the operating instructions or marked on the amplifier. 5. Do not attempt to destroy the grounding or polarization components of this amplifier. 6. Wipe the amplifier with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the amplifier. 7. The power cord of the amplifier should be unplugged from the outlet when left unused for extended periods of time. 8. Do not allow liquids to spill through the amplifier’s openings. 9. An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal. 10. Place the amplifier away from heat sources such as radiators, heat registers, stoves, or other appliances. 11. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts.

12. If an outside antenna is connected to the receiver, be sure the antenna system is grounded to provide some protection against voltage surges, built-up static charges, and lightning strikes. Section 810 of the National Electric Code (NEC), ANSI/NFPA NO. 70-70-1990, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. Caution: Because the Amplifier uses a coaxial cable to • carry the signal from the DC power supply, proper connections are crucial. Carefully follow all instructions in this User’s Guide to avoid damage to your equipment.
Select a Location Place your amplifier close to your input source (external antenna); place the power injector close to your receiver (TV) and an AC outlet. You can mount the amplifier on a wall or another surface using the two supplied screws. • To keep exposed cable to a minimum, you can place the amplifier in your attic. • Do not place the amplifier outdoors. • To prevent interference, do not place the amplifier within six inches of any other electronic device. Route Cables Route a 75-ohm (RG-6 or RG-6QS) coaxial cable (not supplied) from the amplifier to your input source and between amplifier and power injector. Follow these hints when routing cable: • Use only as much cable as is necessary to reach from the amplifier to the input source and receiver. • Do not route cables where they might be cut, crimped, or crushed by normal activities.

Connect to Receiver 1. Connect the TO ANT side of the power injector to the amplifier using a coaxial cable with F-type connectors (not included). 2. Connect the TO TV side of the power injector to one receiver OR to a 75 ohm splitter (not included) and two receivers. 3. Double-check all connections. Connect the supplied AC adapter to the power injector’s DC 12V jack, then plug it into a standard household outlet. The amplifier’s red LED lights when it has power. You can use a RF cable (not included) up to 150 feet (46 m) to connect an extra second amplifier in-line with the first amplifier to enhance the RF signal level.
