@ POWER switch
When this switch is set to the on position, power is
supplied to the tuner’s main circuits. The unit's
POWER switch is geared to selecting the
transformer’s secondary and so even at the STAND-

the power cord is connected to a power outlet.
Disconnect the power cord from the power outlet

This tuning method is used in the following cases:
« When presetting each frequency corresponding to
the desired station using the STATION CALL
switch. (For details on the presetting, see page 6.)
* When tuning in to a station irrespective of the
preset stations reception area, perform tuning
manually using the following procedure.
1 Turn on the POWER of the unit and
the stereo amplifier.
2 Select your desired broadcasting
band using the FUNCTION switch-
es.
3 Press the MANUAL/AUTO selector
so that the AUTO indicator lights.
4 Press the FREQUENCY/CHANNEL
selector so that the CHANNEL in-
dicator goes out.
5 Press the “+” or ’-"" TUNING
switch,
By simply pressing the tuning switch, the tuner will
automatically search for a station and tune in to it. By
pressing “+, the frequency will move upwards, and
by pressing ‘’~’’, the frequency will move downwards.
Each time the switch is pressed, the next higher {or
lower} frequency station will be tuned in.
NOTE:
When AUTO SEARCH is in use, reception may not be
possible over long distances or when signals are weak. At
these times manual tuning is recommended.

<ARB1026>
Caution with Auto-Searc
¢ Since this is a highly sensitive mechanism, the fre-
quency Auto-Search operation may stop even with
weak foreign broadcasts, particularly at night, Also
frequency noise in large cities may cause the seach
operation to stop,
@ When using Auto-Search to preset AM stations, if the
frequency search operation stops too frequently,
changing the position of the AM loop antenna may be
of help in reducing its sensitivity so that only power-
ful, nearby stations are received. After tuning in the
station, be sure to reposition the antenna to its best
position for reception.

FM ANTENNA CONNECTIONS
There are two ways of connecting the FM antenna to
the antenna input terminals: with a 300-ohm twin-lead
feeder or with a 75-ohm coaxial cable. If full justice is
to be done to the tuner’s performance, a 75-ohm coax-
ial cable is recommended since it is more immune than
the twin-lead feeder to noise and interference from ex-
ternal sources. tf an FM antenna has already been
erected outdoors, connect it, referring to the figure.
GROUNDING
Grounding is recommended if reception of FM pro-
grams is impaired by noise. To ground, connect a
thick polyvinyl! insulated wire to the GND terminal
and attach the other end to a metal water pipe or
grounding bar or wind it around a copper plate and
bury it.
NOTE: enn en ennnencn nnn ni nee age
Never connect a wire to a gas pipe tor grounding since

OUTDOOR AM ANTENNAS
The accessory AM loap antenna is quite sufficient if
you live in a strong-signal area. However, an outdoor
AM antenna should be erected if surrounding objects
are interfering with reception or if the stations are dis-
tant and their signals are weak.
NOTE, one
Do not detach the AM loap antenna when using an outdoor
AM antenna.
