1
Read Instructions — Ali the safety and operating instruc-
tions should be read before the appliance is operated.
2
Retain Instructions—The safety and operating instructions
should be retained for future reference.
3
Heed Warnings—All warnings on the appliance and in the
operating instructions should be adhered to.
4
Follow instructions—All operating and other instructions
should be followed.
5
Water and Moisture—The appliance should not be used
near water—for example, near a bathtub, washbowl,
kitchen sink, laundry tub, in a wet basement, or near a
swimming pool, etc.
6
Carts and Stands—The appliance should be used only with
a cart or stand that is recommended by the manufacturer.
7
Wal! or Ceiling Mounting—The appliance should be
mounted to a wall or ceiling only as recommended by the
manufacturer,
8
Ventilation—The appliance should be situated so that its
location or position does not interfere with its proper
ventilation. For example, the appliance should not be
situated on a bed, sofa, rug, or similar surface that may
block the ventilation openings; or, placed in a built-in
installation, such as a bookcase or cabinet that may
impede the flow of air through the ventilation openings.
9 |
Heat-— The appliance should be situated away from heat
sources such as radiators, stoves, or other appliances that
produce heat.
10
Power Sources— The appiiance should be connected to a
power supply only of the type described in the operating
instructions or as marked on the appliance.
11
Grounding or Polarization—The precautions should be
taken so that the grounding or polarization means of the
appliance is not impeded.
12
Power-Cord Protection—Power-supply cords should be
routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying
particular attention to cords at plug, convenience recep-
tacles, and the point where they exit from the appliance.
13
Cleaning— The appliance should be cleaned only as recom-
mended by the manufacturer,
14
Nonuse Periods—The power cord of the appliance should
be unplugged from the outlet when left unused for a long
period of time.
15
Object and Liquid Entry—Care should be taken so that
objects do not fall into and liquids not spilled into the
enclosure through openings.
16
Damage Requiring Service—The appliance should be
serviced by qualified service personnel when:
A. The power-supply cord or the plug has been damaged; oi
B. Objects have fallen, or liquid has been spitled into the
appliance; or |
C. The appliance has been exposed to rain; or
D. The appliance does not appear to operate normally or
exhibits a marked change in performance; or
E. The appliance has been dropped, or the enclosure
damaged.
17
Servicing—The user should not attemot to service the
appliance beyond that described in the operating instruc-
tions. All other servicing should be referred to qualified
service personnel.
18
Power Lines—An outdoor antenna should be located away
from power lines.
19
Outdoor antenna grounding—If an outside antenna is
connected to the tuner, be sure the antenna system is
greunded so as to provide some protection against voltage
surges and built up static charges. Section 810 of the
National Electrical Code, ANSI/NFPA :No. 70—1978,
provides information with respect to proper grounding of
the mast and supporting structure, grounding of the lead-
in wire to an antenna discharge unit, size of grounding
conductors, location of antenna- discharge unit, connec-
tion to grounding electrodes, and requirements for the
grounding electrode,

strength of the station is enough to light the Local seg-
ment of the indicator, there will be no interference and
the tuner will employ the wide-bandwidth Local mode for
optimum music reproduction accuracy. When the signal is
only strong enough to light the DX segments, the tuner
switches to high-selectivity DX mode to block interfer-
ence and provide cleaner reception. Once a station
‘becomes weak enough to cause the tuner to enter DX
mode, Local mode will not be entered even if the signal
becomes stronger, and the Local indicator segment will
not light. Manually detuning the station and tuning it in
again will allow the tuner to revert to Local mode if the
station is strong enough.
* On AM broadcasts the Auto DX feature is ineffective,
and the SIGNAL Q meter only shows signal strength.

o REC CAL SWITCH
This switch provides a signal for setting record levels prior
to recording from the tuner. Pressing the switch activates
the REC CAL oscillator to send a 333Hz 50% FM
modulated signal to the output jacks. This allows the
recording level to be set for a “typical” program leve!
regardless of the current level of the broadcast being
received. Set the decks record level controls so that the
record level meters indicate —6V U-0VU. |
* The REC CAL switch takes precedence over all other
tuner functions; therefore, it should be left off when
not in use.
O TUNING MODE SWITCH
Sets the Tuning button for either Auto or Manual opera-
tion.

The TUNING MODE indicator € lights, and the auto-
search tuning function of the Tuning button @ is acti-
vated.
e MAN'L/FM MONO Position
The TUNING MODE indicator is off, and the manual
tuning function of the Tuning button Q is activated.
FUNCTION BUTTONS (AM/FM SELECTOR)
These switches select either FM or AM broadcasts.
e Pressing the FM button selects FM reception and sets
the digital frequency display to “MHz”.
e Pressing the AM button selects AM reception and sets
the digital frequency display to “kHz”.
O TUNING BUTTON
Use this button to tune in broadcast stations.
e When the TUNING MODE switch O has been set to
AUTO. |
Pressing the DOWN side of the button scans the broadcast
band downwards until a station is encountered, then stops
with the station perfectly tuned in {Auto-Search Tuning).
Pushing the button again scans progressively lower
frequencies until the next station is found. When the
bottom of the band is reached, the frequency is set to the
top of the band and the scan continues downward. Press-
ing the Up side of the button scans the band upwards in
the same way.
e When the TUNING MODE switch O has been set to
MAN'L,
Pressing the DOWN side of the button scans down the
band only as long as the button is held, and pressing the
Up side scans upwards as long as the button is held. In
either case scanning stops when the button is released.
Unlike automatic scanning, attempting to tune beyond
the upper or lower limit of the band will cause tuning to
stop, without jumping to the other end of the band. Push-
ing the Tuning button briefly causes the frequency to
advance 0.1MHz on FM or 1kHz on AM.

MEMORY. |
® MEMORY BUTTON |
Pushing this button causes the indicator on the button to

Multipath is an effect similar to television ghosting; it
distors the received signal and also causes poor stereo
separation and noise. As shown in fig, radio waves which
travel directly from the transmitter to the receiving antenna
are mixed with waves which reflect off nearby objects such
as buildings. Because the path taken by the reflected waves
is longer than the direct path, the time required for the
waves to arrive at the antenna is also longer. The mixing of
the directly received signal and the delayed signal notice-
ably degrades reception quality. Multipath interference can
be greatly reduced by the use of a high-quality directional
antenna oriented in the proper direction.

Before assuming that your tuner is faulty, check the following troubleshooting list which details corrective action you can
take yourself without having to call a service engineer. If you have any doubts or questions, get in touch with your nearest
Yamaha dealer.

The FM antenna should be put up as 5 high : as possible, away
from the road, and a coaxial cable used.
Noise from thermostats or other electrical equipment.
Attach a noise suppressor to the equipment causing the

The FM stereo reception is noisy.
Because of the characteristics of FM stereo broadcasts,
this is limited to cases vwhere the transmitter is far away
or the antenna input is poor.
Check the antenna connections.
Try using a multipie element FM antenna.
