TM-155 (310-1958) Installation Faxback Doc. # 7040 CONNECTING TO AN AMPLIFIER Before you make connections, be sure: -The AC power cord is not plugged in. -The POWER button is in the out position. Use standard, shielded audio cable with phone plugs to connect the tuner to the amplifier. Connect the tuner's R and L OUTPUT jacks to the corresponding right and left input jacks on the amplifier. CONNECTING AN EXTERNAL ANTENNA The tuner comes with an FM line-cord antenna, which is attached to one of the FM ANT 300-ohms terminals on the back of the tuner. The line-cord antenna provides adequate FM reception in most metropolitan areas. However, to improve FM reception, one can connect any one of the following types of external antennas. -Dipole antenna (for indoor use only). -Rabbit-ear antenna (for indoor use only). -Outdoor TV Antenna. -Separate Outdoor FM Antenna. The local Radio Shack store has a wide variety of antennas to choose from. Before connecting any of these antennas, the line-cord antenna must be disconnected from the FM ANT 300-ohms jack. CONNECTING A DIPOLE ANTENNA A dipole antenna (Cat. No. 42-2385) is inexpensive and easy to mount. Connect the dipole antenna's lug connectors to the tuner's FM ANT 300-ohms terminals. Then attach the antenna to a wall close to the tuner or to the back of a cabinet. Usually, the higher the mounting position, the better the reception. CONNECTING A RABBIT-EAR ANTENNA A rabbit-ear antenna (FM or VHF) requires a flat surface. Connect the antenna wire's lug connectors to the tuners FM ANT 300 ohm terminals. Then place the antenna base on a flat surface, such as a shelf or table. NOTE: If the antenna does not have an attached antenna wire, use standard 300-ohm twin-lead for the connection. CONNECTING AN OUTDOOR TV ANTENNA The tuner cannot connect to the existing TV antenna. To do so, one needs a VHF/UHF/FM signal splitter (Cat. No. 15-1252, not supplied). Connect the TV antenna wire to the splitter's input terminal. Then connect the splitter's twin-lead, 300-ohm output to the tuner's FM ANT 300-ohm input terminals. CONNECTING A SEPARATE OUTDOOR FM ANTENNA Some specially designed outdoor FM antennas can receive stations up to 110 miles away. This type of antenna is ideal if one frequently listen to distant stations. For the best reception form an outdoor FM antenna, use 75-ohm coaxial cable to connect the antenna to the tuner. If this coaxial cable is used, a matching transformer is needed (Cat. No. 15-1140). To connect an outdoor FM antenna, follow these steps: 1. Connect one end of the coaxial cable to the antenna's terminal. 2. Connect the other end of the cable to the matching transformer's 75-ohm terminal. 3. Connect the matching transformer's 300-ohm connectors to the tuner's FM ANT 300-ohm terminals. To minimize interference, position the outdoor antenna away from telephone wires, electrical wiring, or heavily traveled streets. WARNING: When installing or removing an outdoor antenna, use extreme caution. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches the power line, contact with the antenna mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna. Do NOT attempt to do so yourself. CONNECTING TO POWER After finnished making the antenna connections, plug the tuner's AC cord into standard AC outlet. CAUTION: The cord's plug is polarized and fits only one way. Do not force the plug into the outlet. Follow these steps to operate the tuner: 1. Press POWER. The frequency display lights. 2. Press AM/FM for the desired band - in for FM; out for AM. 3. Rotate the tuning control to tune to the desired station. If you tune to a stereo FM broadcast, the stereo indicator lights. NOTE: Press MONO to the IN position to improve reception of weak stereo signals. Press MONO to the OUT position to resume normal stereo reception. 4. After finnished using the tuner, press POWER. The frequency display light turns off. (smc-02/28/94)
