Adjusting Seek Sensitivity
The seek tuning function of this tuner lets
you select between a local setting for recep-
tion of strong stations only, and a DX (dis-
tant) setting for reception of weaker sta-
tions. The local setting also has four seek
tuning sensitivity levels for FM and two lev-
els for AM to match local conditions.
Changing the Local Seek Sensitivity
1.Use button [6] to select a band.
2.Hold down the button [15] for more than
two seconds, and the display will show
you the current local seek sensitivity for
about five seconds.
3.While the local seek sensitivity remains
on the display, press the (+) side of button
[7] to increase the sensitivity level, and
the (-) side to decrease the level as
shown below.
FM: 1-1 L-2 =L-3 = 1-4
AM: L-1 = L-2
The L-4 setting allows reception of only
the strongest stations, while lower set-
tings let you receive progressively weaker
stations.
* The display of local seek sensitivity re-
turns to the frequency when about 5 sec-
onds have elapsed after the change of
sensitivity.
Switching between Local and DX
Press button [15] to switch between Local
and DX (distant) seek tuning.
When “LOC” [22] is shown on the display,
seek tuning is performed with the local seek
sensitivity. Otherwise, seek tuning is per-
formed with the DX seek sensitivity.
Manual Tuning
Use manual tuning when stations are too
weak to be picked up by seek tuning.
1.Press both (+) and (-) sides of button [7]
at the same time to clear “SEEK” [23].
2.Each press of the (+) side of button [7] in-
creases the frequency in 0.2 MHz steps in
the FM band, 10 kHz in the AM band.
Pressing the (-) side of button [7] decreas-
es the frequency. Holding down either
side of button [7] changes the frequency
at high speed.
Switching between FM Stereo and
Mono
Generally, it is best to allow the “Super
Tuner” function to automatically set the op-
timum listening conditions. When stereo
broadcasting is received, “CD” [28] will ap-
pear on the display. When there is a large
amount of noise, you can press button [17]
for clearer mono reception (“MO” [27] will
appear on the display).

About cassette tapes
* Do not use tapes longer than C-90-type
(90 min.) cassettes. Longer tapes can in-
terfere with tape transport.
* Storing cassettes in areas directly ex-
Posed to sunlight or high temperatures
Can distort them and subsequently inter-
fere with tape transport.
+ Store unused tapes in a tape case where
there is no danger of them becoming
loose or being esposed to dust.
Cleaning the head
If the playback head becomes dirty, sound
quality will suffer. Periodically (once or
twice a month) clean the head with a cotton
swab soaked with alcohol.

Listening to a tape
1.Insert the cassette tape into the slot [3],
and power will be turned on and the tape
begin being played back.
At this time, the tape running direction indi-
cator [33] will light up.
2.Adjust volume and tone (see page 4).
3.To eject the cassette tape, press the but-
ton [2].
* Be sure to eject the tape when the front
panel is removed, or the vehicle’s ignition
is turned OFF. Leaving the tape in the unit
can deform the pinch roller causing wow
and flutter during tape playback.
A loose or warped label on a cassette
tape may interfere with the eject mecha-
nism of the unit or cause the cassette to
become jammed in the unit. Avoid using
such tapes or remove such labels from
the cassette before attempting use.
Do not try to eject the cassette immedi-
ately after insertion, as it will cause mal-
function. Wait a few seconds.
.
Changing Program
Push the fast forward and rewind buttons
[5] together to switch from one side of the
tape to the other (from Side A to Side B or
vice versa).
Using Fast Forward and Rewind
Since the transport can be in either direc-
tion, both the left and right high-speed tape
transport buttons [5] can be regard as fast
forward/rewind buttons. For fast forward,
press the high-speed tape transport button
[5] that corresponds to the direction that is
shown by the direction indicator [33]. When
the end of the tape is reached, playback will
automatically begin from the opposite side
of the tape (Auto-reverse). For rewind,
press the button [5] that is opposite that of
the direction shown by the direction indica-
tor [33]. When the end of the tape is
reached, playback will automatically begin
from the beginning of the same side of the
tape (Auto-replay).
When you release fast forwad/rewind, light-
ly press button [5] located on the opposite
side of the one you pressed to fast foward
or rewind.
+ “<>” (33) will flash when the tape is fast
forwarding or rewinding.

8. CONNECTING THE UNITS
Note:
Before making final connections, make
temporary connections then operate the
unit to check for any connecting cord pro-
blems.
Refer to the owner’s manual for details
on connecting the various cords of the
power amp and other units, then make
connections correctly.
Be sure to connect the memory power
supply lead (orange) to a terminal that is
always supplied with power regardless of
the vehicle’s ignition switch position. If
this connection is made incorrectly or is
forgotten, the unit will not work at all.
Don't pass the orange lead through a
hole into the engine compartment to con-
nect to the battery. This will damage the
lead insulation and cause a very danger-
ous short.
Since a unique BPTL circuit is employed,
never wire so the speaker leads are di-
rectly grounded or the left and right
speaker © leads are common.
Speakers connected to this unit must be
high-power types possessing minimum
rating of 30W and impedance of 4 to 8
ohms. Connecting speakers with output
and/or impedance values other than
those noted here can damage the speak-
ers.
* When the unit is mounted in a vehicle
whose ignition switch does not have the
ACC (accessory) position as shown in Fig.
6, be sure to connect the red lead of the
unit to the terminal controlled by the igni-
tion switch ON/OFF position. If you do
not, the vehicle battery may go flat when
you leave your vehicle for several hours.
