[. . . ] To disconnect the cord, pull it out by grasping the plug. AC power cord must be changed only at the qualified service shop. 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. [. . . ] Return to a previous stage in the menu mode. If you press one of the buttons on the main unit, the minimal display changes to the full display with the selected brightness. After about 4 seconds, the display returns to the display mode you selected. This tuner lets you enter a station's frequency directly by using the numeric buttons (direct tuning). If you don't know the frequency of the station you want, see "Receiving broadcasts by scanning stations (Automatic tuning)". Before you begin, make sure you have: · Z If you enter a frequency not covered by the tuning interval The entered value is automatically rounded up or down to the closest covered value. With automatic tuning you can quickly tune in a station without having to know its frequency. Turn TUNING/SELECT slightly and release it when the frequency numbers start changing. Turn the knob to the right for a higher frequency; turn it to the left for a lower frequency. When the tuner locates a station, it stops automatically, "TUNED" appears in the display. the signal meter indicates the strength of the broadcast signal. You can use the digital signal meter to check the signal strength of FM frequencies. the display range is from 16 to 70 dB (1 µV of radio frequency voltage = 0 dB). To obtain a signal to noise ratio sufficient for receiving a stereo broadcast, we recommend a reading greater than 50 dB. (You can also change the FM MODE while using the signal meter to determine the best reception. ) The ST-S7 also lets you use the digital signal meter with the AM band. With AM, display range is from 0 to 15 (larger values indicate stronger signals). This tuner's Active Selection Mode (ASM) is factory preset to find the best aerial attenuator (ANT ATT), intermediate frequency band (IF BAND), and FM MODE settings for each frequency automatically. You can, however, choose each setting manually according to your preference. If you don't want to use the ASM function, turn it off. Press ASM to turn the active selection mode off or on. When ASM is turned on, the ASM indicator appears in the display when you select the FM band. [. . . ] * Not all FM stations provide RDS service, nor do they provide the same types of services. ⷠIf you make EON CONTROL connections to a compatible Sony amplifier, the amplifier automatically switches the function mode to TUNER whenever the tuner receives a programme you are monitoring. The tuner starts searching the preset RDS stations for the programme ("Search" and the programme type are displayed alternately). When the tuner finds the programme you are looking for, it stops searching. [. . . ]
