Sony Corporation Personal Audio Division Published by Sony Techno Create Corporation 9-887-734-01 2007E04-1 2007. 05 FM/AM DIGITAL RADIO HD Radio Broadcasting was approved by the Federal Communications Commission in October 2002 as the system for digital AM and FM broadcasting in the U.S. HD Radio technology features include: Static-free, clear radio reception. FM Multicasting the ability to broadcast multiple program streams over a single FM frequency. A variety of “data services,” including text-based information artist name, song title, etc. scrolled across your receiver display. Digital broadcasts in the same frequencies as analog broadcasts; listeners do not need to learn a new station number and todays stations remain at their current place on the dial. HD Radio technology is developed and licensed by iBiquity Digital Corporation and supported by the leaders of the broadcasting, consumer electronics and automotive industries.

Notice that the minus side of a tantalum capacitor may be dam- aged by heat. z UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the lead free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.) : LEAD FREE MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

ELECTRICAL PARTS LIST.30 1.5 k0.15 F AC voltmeter (0.75 V) To Exposed Metal Parts on Set Earth Ground SAFETY CHECK-OUT After correcting the original service problem, perform the fol- lowing safety check before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microampers.). Leakage current can be measured by any one of three methods. 1.A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments. 2.A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3.Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indica- tion is 0.75 V, so analog meters must have an accurate low- voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all bat- tery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A) Fig. A. Using an AC voltmeter to check AC leakage. RadioFans.CN 3 XDR-S3HD SECTION 1 GENERAL This section is extracted from instruction manual. Tip The preset can be selected by pressing the number button of the remote commander. Press ENTER after the preset number is selected. Scan tuning The unit will automatically scan the selected band. In HD scan, HD Radio stations are scanned. 1Press POWER to turn on the radio. 2Press BAND to select the band AM or FM. 3Press MENU to show the menu display. 4Turn TUNE/SELECT clockwise or counterclockwise to select “SCAN” or “HD SCAN,” then press ENTER. Scanning of the selected band starts. When a station is received, scanning pauses for 3 seconds and then continues. 5When the unit tunes in to the desired station, do any of the following operations to stop scanning. Press ENTER on the unit or remote commander. Press SCAN or HD SCAN on the remote commander. 6If necessary, turn TUNE/SELECT clockwise or counterclockwise to tune in to the station more precisely. 7Adjust the volume using VOLUME. Tip You can scan a station directly by pressing SCAN or HD SCAN on the remote commander. To listen with the headphones You can enjoy the radio and external equipment connected to the line in by the headphones (not supplied). Connect the headphones (not supplied) to the i (headphone) jack. The speaker is deactivated when the headphones are connected. Changing the display mode and settings To change the display mode Press DISPLAY.
