filter to achieve characteristics equal to those of the optimum
analogue fitter. This permits clear and vivid playback.

receivers and amplifiers or a separately purchased remote contro!
unit (RC-241) is used, the DCD-315 can be operated from the

disc.
This function will only work for discs with a total of 20 tracks or less.
Also, when this function is used the mode is automatically set to the
Program mode, so direct search is not possible.
The auto edit function is cleared when the[_SToP_]buttonis pressed.
The data for the total playing time recorded on the disc and the actual
total playing time of the tracks differ, so there may be a difference
between the time displayed in the stop mode (the total playing time)
and the total of the times of the first and second halves in the auto edit
mode (about 2 seconds).

Notes on the Batteries
* - The remote control unit uses standard size AA dry cell batteries.
* The batteries will need to be replaced approximately once a year.
Replacement may be necessary earlier depending on how much the
remote control unit is used.
« — If, in less than a year from the time new batteries were inserted, the
remote control fails to operate the CD player from a near-by position,
it is time to replace the batteries.
* — Insertthe batteries property, following the polarity diagram inside the
battery compartment, in other words make sure (+) and{-) terminals
are properly aligned.
* Batteries are prone to damage and leakage. Therefore:
* Donot combine new batteries with used ones.
*¢ Donot combine different types of batteries.
* Donot jumper opposite poles of the batteries, expose them to
heat, break them open nor expose of them in open fire.
* — Ifthe remote control unit is not to be used for a long period of time,
remove the batteries from the unit.
* Ifthe batteries have leaked, remove any traces of battery fluid from
the battery compartment, wiping thoroughly with a dry cloth. Then
insert new batteries.
(2) Directions for Use
« Operate the remote contro} unit while pointing it towards the remote
control sensor on the CD player (see below). When a remote contro!
signal is received, the remote contro} indicator on front of the CD
player lights briefly.
* The remote control unit can be used at a distance up to 8 meters in
astraightline from the CD player. This distance decreases if there are
obstructions blocking the signal path or when the remote control unit
is operated at an angle from the remote control sensor.
* The buttons on the remote contro! unit have identical functions with
those on the CD player. However, the following functions cannot be
remote controlled: Power ON/OFF.
Do not press identical buttons on the CD player and remote control
unit simultaneously as this may cause malfunction.
* — Theremote control unit may be difficult to operate if the remote contro!
sensoris exposed to strong light, such as direct sunlight or light from
fluorescent lamps, or if there are obstacles between the remote
control unit and the sensor.
* Direct track selection
Using the track number buttons (1 ~ 10, +10), tracks can be directly
assigned for playback.
* Track selection while programming
Press the program button (PROG) and then the track numbers you
wish to enter into the memory.
Example: PROG + 3 + +104 135...
(Tracks 3, 11,5 and so on are entered into the memory.)
Memorized tracks are erased by pressing the Direct button (DIRECT).
* Correct use of the track number buttons
Direct selection of single-digit tracks is easy by just pressing the
desired track number button. For tracks with numbers trom 114 andon,
first press the +10 button and then a single-digit button. E.9., toselect
track 22, press the +10 button twice and then press the 2 button.
INSTALLATION PRECAUTIONS
The CO player uses a microcomputer for controlling internal electronic
circuits. In the event that the player is used while a near-by tuner or TV is
tumed on, although unlikely, interference could occur either inthe sound
from the tuner or the picture of the TV. To avoid this, please take the
following precautions:
* Keepthe CD player as far away from the tuner or TV set as possible.
* Keep the power cable and connecting cable of the CD player
separate from the antenna wires of the tuner and TV.
¢ — Interference is particular likely to occur when an indoor antennaora
300-ohm feeder cable is used. Thus, use of an outdoor antenna and
75-ohm coaxial cable is strongly recommended.
TROUBLESHOOTING
