IMPORTANT
Please record the serial number of your unit
in the space below.
Model: KX-800/U
Serial No: EOl..//D885U
The serial number is located on the rear of
the unit.
Retain this Owner's Manual in a safe place
for future reference.
1. This unit is a sophisticated stereo cassette
deck. To ensure proper operation for the best
possible performance, please read this manual
carefully.
2. Choose the installation of your unit carefully.
Avoid placing it in direct sunlight or close to
source of heat. Also avoid locations subject to
vibration and excessive dust, heat, cold or
moisture. Keep it away from such sources of
hum as transformers or motors.
3. Do not open the cabinet as this may result in
damage to the deck or electrical shock. If a
foreign object should get into the deck, contact
your local dealer.
4. When removing the power plug from the wall
outlet, always pull directly on the plug; never pull
the cord itself.
5. Do not use force when operating switches
and knobs.
6. When moving the deck, be sure to first pull
out the power plug and remove all cords
connecting the deck to other equipment.

I
8. Never allow metallic items (e.g. screwdrivers,
tools, etc.) to come near the record/playback
head assembly. Doing so may not only scratch
or damage the head's mirror-smooth finish, it
may change the magnetic characteristics of the
heads, causing a deterioration in reproduction
performance quality.
9. Although the record/playback head used in
this unit is a high quality Amorphous head with
outstanding reproduction characteristics, it can
become dirty through the use of old tapes of
from dust accumulation over time.
This can have a serious effect on reproduction
quality. Clean the h~ads regularly with one of the
commonly available head cleaners or with
cleaning solutions as explained later in this
manual.
10. Be sure to read the "Troubleshooting"
section of this manual for advice on common
operating errors before concluding that your unit
is faulty.

4D MPX FILTER switch
Press this switch when recording from an FM station while using the
Dolby-NR system. As the 19 kHz pilot signal may leak into the audio
output, depending on the tuner and the broadcast condition and may
cause improper operation of the Dolby NR system, this switch should be
turned on when recording from an FM station to filter out the (19 kHz)
pilot signal. This switch should be turned off when recording from other
program sources.
4D DOLBY NR buttons
OFF/ON: For recording and playback without using the DOLBY NR
system, set this button to OFF.
B TYPE/C TYPE: Dolby noise reduction is an extremely effective
method of reducing background hiss on tapes. This unit incorporates
both Dolby B NR and the Dolby C NR systems. Dolby C NR is
approximately twice as effective as Dolby B NR.
Tapes recorded with Dolby B NR should be played back with Dolby B
NR on, set the OFF/ON button to ON and B TYPE/C TYPE button to B
TYPE. Tapes recorded with Dolby C NR should be played back with
Dolby C NR on, set the OFF/ON button to ON and B TYPE/C TYPE
button to C TYPE.
*Dolby and the double D symbol are trademarks of Dolby Laboratories
Licensing Corp. Dolby noise reduction system manufactured under
license from Dolby Laboratories Licensing Corp.

4D dbx button
When recording with dbx NR, input signals with a large dynamic range
are compressed to 1/2, and expanded by a factor of 2 to their original
state when played back. This means that a large dynamic range can be
obtained even from cassette tapes with small dynamic range recordings,
and noise can also be reduced at the same time. If metal tapes are used
for recording and playback, a dynamic range which would have been
thought impossible with cassette tapes can be obtained. For recording
and playback with the dbx system, set this button to ON.
For playing back tapes which are not dbx recorded, set to OFF position.
*"dbx" is a trademark of dbx incorporated.
4D REMOTE CONTROL sensor
Receives the signal from the remote control transmitter.
CD PRESET REC LEVEL controls
Adjusts the input level of the recording signal coming from the rear panel
LINE IN/REC jacks, and adjustable signal level is displayed on the PEAK
level meters. Independent left/right controls also permit balance level
setting.
~AUTO MO DE selector
OFF: For normal playback or recording, set to this position.
FULL REPEAT: One side of the cassette is repeatedly played back 8
times from beginning to end.
Q-M REPEAT: Desired section can repeatedly be played back 8 times
between "0.00" on linear counter reading and the counter number
memorized with the MEMORY button.
TIMER PLAY: By using a commercially available audio timer, this
function permits timer activated playback.
TIMER REC: By using a commercially available audio timer, this function
allows you to carry out unattended recording.
• Be sure to set this selector to OFF when not using the repeat playback
feature or the timer feature. If power is turned on with a cassette
loaded in the deck and the selector in the TIMER REC position, the
record mode will be engaged and the prerecorded contents of the tape
will be erased.
4D BIAS ADJUST control
This function is provided to adjust the recording bias to its optimum value
according to the type of tape used.'
