On power sources Before operating the unit, be sure that the operating voltage of your unit is identical with that of your local power supply. Unplug the unit from the wall outlet if it is not to be used for an extended period of time. To disconnect the cord, pull it out by grasping the plug. Never pull the cord itself. AC power cord must be changed only at the qualified service shop. On placement Place the unit in a location with adequate ventilation to prevent heat buildup and prolong the life of its components. Do not place the unit near heat sources, or in a place subject to direct sunlight, excessive dust or mechanical shock. Do not place anything on top of the cabinet which might block the ventilation holes and cause malfunctions. Do not install the appliance in a confined space, such as a bookcase or built-in cabinet. On cleaning the cabinet Clean the cabinet, panels and controls with a soft cloth lightly moistened with a mild detergent solution.

Thank you for purchasing the Sony FM Stereo FM/AM Tuner. Before operating the unit, please read this manual thoroughly and retain it for future reference. Convention The following icon is used in this manual: Indicates hints and tips for making the task easier. RadioFans.CN 4GB Unpacking Check that you received the following items with the tuner: Audio cord (1) AM loop aerial (1) FM wire aerial (1) EON connecting cord (1) Getting Started around the frame of the aerial. Be careful to unwrap only the braided section of the lead wire. Do not unwrap more than 3 lengths of the lead wire. Also, be careful not to unbraid the lead wire. 3Assemble the supplied aerial as shown below. 4Connect the AM loop aerial to the AM terminals on the back of this unit. 5Adjust the aerial direction for the best reception. The AM loop aerial has a directivity which detects the signal from some angles more strongly than others. Set the aerial to the orientation which provides the best receiving condition. If a high pitched noise (beat noise) occurs when recording AM broadcasts, adjust the position of the AM loop aerial so that the noise disappears. If you live in a building constructed of reinforced concrete, or with a steel frame, you may not be able to achieve good reception since the radio waves become weaker indoors. In this case, we recommend connecting an optional aerial such as the Sony AN-1. For stations that are difficult to receive Try repositioning the loop aerial while tuning. Placing the supplied AM loop aerial near a window will help improve reception quality. Hooking up the System Before you get started Turn off the power to all components before making any connections. Do not connect the mains lead until all of the connections are completed. Be sure to make connections firmly to avoid hum and noise. When connecting an audio cord, be sure to match the colour-coded pins to the appropriate jacks: White (left) to White; and Red (right) to Red. AM aerial hookups This section describes how to connect the supplied AM loop aerial. For the specific location of the AM ANTENNA terminals, see the illustration below. What will I need? AM loop aerial (supplied) (1) 1Before assembling the supplied aerial, pull the lead wire out from the slot in the aerial frame. 2Unwrap 3 lengths of the braided lead wire from AM loop aerial ANTENNA FM 75 COAXIAL AM y AM ANTENNA RadioFans.CN 5GB FM aerial hookups With an FM outdoor aerial, you can obtain a higher FM broadcast sound quality. We recommend that you use the supplied FM wire aerial only temporarily until you install an FM outdoor aerial. For the specific location of the FM ANTENNA terminal, see the illustration below. What will I need? FM wire aerial (supplied) (1) FM outdoor aerial (not supplied) (1) and 75-ohm coaxial cable with IEC female type connector (not supplied) (1) Connect the supplied FM wire aerial or an FM outdoor aerial (not supplied) to one of the FM terminals on the back of this unit. Connecting a ground wire If you connect an outdoor aerial, be sure to connect a earth lead (not supplied) to the AM ANTENNA y terminal (in addition to the AM loop aerial) for lightning protection. Getting Started FM ANTENNA IEC female type connector Amplifier hookups Connect the tuner to an amplifier. Be sure to turn off the power to both components before connection. For the specific location of the terminals, see the illustration below. What cables will I need? Audio cord (supplied) (1) Connect the white plugs to the white (L) jacks and the red plugs to the red (R) jacks. Insert the plugs completely into the jacks; incomplete connections may cause noise. EON CONTROL Red (R) White (L)White (L) Red (R) TUNER IN RL RL LINE OUT Amplifier Tuner If you have a Sony amplifier equipped with an EON CONTROL IN terminal Use the supplied EON connecting cord to connect the EON CONTROL OUT terminal on the tuner to the EON CONTROL IN terminal on your amplifier.

Additionally, “Auto-betical select” only stores the stations with the clearest signals. If you want to store FM or AM (MW and LW) stations one by one, see “Receiving Broadcasts” on page 9 and “Presetting Radio Stations” on page 10. 1Press POWER to turn on the tuner. 2Turn on the amplifier and select the TUNER mode. 3Press AUTO-BETICAL SELECT. “Yes” and “No” appear in the display. 4Turn TUNING/SELECT to select “Yes”. 5Press AUTO-BETICAL SELECT again. The tuner scans and stores all the FM and FM RDS stations in the broadcast area. For RDS stations, the tuner first checks for stations broadcasting the same programme, then stores only the one with the clearest signal. The selected RDS stations are sorted alphabetically by their Programme Service name, then assigned a two-character preset code. For more details on RDS, see page 13. Regular FM stations are assigned two-character preset codes and stored after the RDS stations. To change the location of, or erase, a preset station See “Organizing the Preset Stations” on page 12. Notes If you move to another area, repeat this procedure to store stations in your new area. For details on tuning stored stations, see page 7. The FM MODE setting is also stored along with the station. If you move the aerial after storing stations using Auto- betical select, the stored settings may no longer be valid. If this happens, store the stations again. Getting Started Selecting the German Display You can choose either an English or a German language display. The factory preset language is English. To change the display to German, follow the steps below. 1Press POWER to turn off the tuner. 2While holding down the “2” button, press POWER to turn on the tuner . “Deutsch” appears in the display.
