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.
–Avariety 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 today’s 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.
HD RadioTM Technology Manufactured Under License From
iBiquity Digital Corporation. iBiquity Digital, the HD Radio
logo, and the HD logo are registered trademarks of iBiquity
Digital Corporation. HD RadioTM is a trademark of iBiquity

SERVICE NOTES
Notes on Chip Component Replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
zUNLEADED 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 40°C 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 350°C.
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.

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)

Connecting the
antenna
To connect the AM loop
antenna
The shape and the length of the antenna is designed to
receive AM signals. Do not dismantle or roll up the
antenna.
1Remove only the loop part from the plastic
stand.
2Set up the AM loop antenna.
3Connect the cords to the AM antenna
terminals.
Cord (A) or cord (B) can be connected to either
terminal.
AB
Only insert up
to here.
4Make sure the AM loop antenna is connected
firmly by pulling softly.
Adjusting the AM loop antenna
Find a place and an orientation that provide good
reception.
•Do not place the AM loop antenna near the unit or
other AV equipment, as noise may result.
•If you use an external polarized AM antenna, be sure
to connect the ground cord to the Uterminal. The
supplied AM antenna cord has no polarity.
Tip
Adjust the direction of the AM loop antenna for best AM
broadcast sound.
To connect the FM antenna
This unit comes supplied with an FM wire antenna and
FM dipole antenna. Connect an antenna that provides
good reception to the FM antenna terminal.
Adjusting the FM wire antenna
Be sure to fully extend the FM wire antenna, and keep it
as horizontal or vertical as possible.
Adjusting the FM dipole antenna
Be sure to fully extend the FM dipole antenna. Attach
the antenna in the shape of a T to a high position on a
wall away from this unit.
Tip
If you have poor FM reception, use a 75 Ωcoaxial cable
(not supplied) to connect the unit to an outdoor FM
antenna as shown below.

• Waveforms
— MICON Board —
for schematic diagrams:
•All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
•All resistors are in Ωand 1/4W or less unless otherwise
specified.
•%: indicates tolerance.
•f: internal component.
•C: panel designation.
for printed wiring boards:
•X: parts extracted from the component side.
•Y: parts extracted from the conductor side.
•f: internal component.
•: Pattern from the side which enables seeing.
•A: B+ Line.
•Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : FM1
•Voltagesare taken with a VOM(Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
•Circled numbers refer to waveform.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
Note: The components identified by mark 0or dotted line
with mark 0are critical for safety.
Replace only with part number specified.
