Tuner Reception
Press the FM or AM Input Selector button and make sure that the
TAPE-2 MONITOR indicator is off and audio muting is off.
@ Tuning with the TUNING buttons
< DOWN, UP >
{aan es es |
To tune ina FMor AM station not stored in the memory, press one
of the Tuning selector buttons. If you press UP, the frequency is
increased. Pressing DOWN decreases. Note that the frequency is
changed in 50kHz (or 200kHz) steps in FM and 9kHz (or 10kKHz)
steps in AM when the Tuning selector button is pressed in single
steps. If this button 1s pressed continuously for more than 0.5
seconds, the auto tuning mode ts entered, and frequencies are
scanned automatically. When a broadcast signal is received,
scanning stops and that frequency is displayed. If a different
frequency is desired, press the button once again.
@® The Tuned indicators [1% !)! will light if the broadcast is being
properly received. These indicators do not light for weak broad-
casts. The red“ ¥ ” indicator flashes during scanning. To receive
a weak FM broadcast, set the MUTE/MODE button to the OFF
position and select the frequency of the desired broadcast station.
m Receiving a station by inputting the frequency for the station
directly (Direct Tuning)
if the frequency for the desired station is known, input the frequency
number directly.
(2) DIRECT TUNING
(3) Number Buttons
So)
Press the AM or FM button of the Input selector buttons.
Press the DIRECT TUNING button.
@® *- or *-” will flash for 16 seconds in the Frequency Display.
' Input the desired frequency number by using the Number Buttons
while the cursors are flashing. For instance, if you wish to receive
the station of 88.10MHz, press the Number Buttons, 8, 8, 1 and 0.
@ Inareas where AM frequencies are set in 10kHz steps, inputting
a number to the 10kHz digit sets 0 to the 1kHz digit automati-
cally. .
@ Ifthe desired frequency set in this operation does not exist, the
frequency which is the nearest and lower than the desired
frequency will be received. If the frequency set is not in the
receive frequency range, the frequency flashes for two seconds
and then the previous frequency will be displayed.
® |fawrong frequency has been set, press the DIRECT TUNING
button and start again.

m@ How to use the FM Muting/Mode Button (MUTE/MODE)
NOTES:
In the Muting ON (STEREO) setting, FM stereo reception is
possible and the muting circuit suppresses interstation noise and
weak FM stations. In the OFF (MONO) setting, interstation noise
will be heard and even weak FM stations can be received.
(Muting/Mode operation is effective for only FM reception. }
MUTE/MODE
® The Stereo indicator will light up if the broadcast is being
received in stereo. The Stereo indicator will not light up if the
broadcast is monaural or too weak to be received in Stereo.
Automatic Precision Reception System (FM Mode) —_
APR system is Onkyo’s unique computer-controlled system. APR
system automatically sets the RF stage gain (Local/Distant), ste-
reo/mono reception modes to the proper settings for the qualily of |
the broadcast currently being received. This indicator changes |
each time the APR circuit switches between the LOCAL/DX or |
AUTO/MONCO to show the current APR setting. (APR system ts
effective for only FM reception.)
When MUTE/MODE button is not ON, the APR Mode selection
function does not operate, and the STEREO MODE indicator is
forced to “MONO”.
The “MONO?” indicator lights up for FM monaural reception.
The RF MODE wiil indicate LOCAL when sufficient signal is
received.
Memory Preservation |
This unit does not require memory preservation batteries. A built-
in memory power back-up system preserves the contents of the
memory during power failures and even when the unit is un-
plugged. The unit must be plugged in and the power switch turned
on and off once in order to charge the back-up system. Note that
since this is not a permanent memory, the power switch must be
turned on and off a few times each month to keep the back-up
system operative. |
The memory preservation period after power has been turned off |
varies depending on climate and placement of the unit. On the
average, memory contents are protected over a period of a few
weeks after the last time power has been turned off. This period is
shorter when the unit is exposed to a highly humid climate.
