SYNCHRONIZED RECORDING CONTROL
The PMD350 is capable of connecting with other Marantz RC-5
based products to allow for synchronized start of the product
recording through the starting of the play function of the CD player
or the tape transport of the PMD350.
By connecting the RC-5 output jack to the RC-5 input jack of
another Marantz recorder, the PMD350 will issue a command for
the recording to start as soon as the play control button is pressed
on the PMD350. Pressing the stop or the stop/eject control button
on the PMD source deck will place the attached component into
the record pause mode.
During the cascade recording mode, the PMD350 can be attached
to other Marantz RC-5 based decks for the purpose of small scale
duplication of the dubbing source. This is accomplished by linking
the RC-5 output connector to the RC-5 input of the recording deck
and placing the PMD350 reverse mode control switch into the
cascade position.
REMARKS
CAUTION
• If you must stop playback or recording in the middle of a tape,
be sure to press the STOP
-
button first, then turn the power off.
If the power is turned off in the middle of an operation, the
cassette tape remains loaded, and it may be impossible to eject.
In such a case, turn the power on, enter PLAY mode, then press
STOP, and the eject the tape.
• The same caution as above applies in case of power failure.
To prevent damage, never attempt to force the removal of a
cassette while the power is off.
ERASURE OF TAPE
When a program source is recorded onto a tape, the previously
recorded sound is erased automatically, and replaced with the new
recording. If you wish to erase a tape without recording, set the
REC LEVEL control to the minimum(0) position and let the tape
travel in the Record mode.
AUTO TAPE SELECTOR
This unit is equipped with an auto tape selector whitch automati-
cally sets the bias and equalizer level using the detection holes
porovided in the cassette shell. The bias and equalizer levels are
automatically set according to the type of cassette as follows. (See

TO PROTECT VALUABLE RECORDINGS
In the record mode, information previously recorded on the tape
will automatically be erased. To prevent this from happening, use
a small screwdriver to break out one or both safety tabs (See Figure
4).
It is possible to restore the recording capability of either side of the
cassette by covering the opening with clear adhesive tape (See
Figure 5).
CARE AND MAINTENANCE
This section describes the care and maintenance tasks that must
be performed to optimize the operation of your Marantz equip-
ment.
MAINTENANCE FOR TAPE
Head Cleaning
If the heads are not cleaned for a long period, dirt or dust may be
deposited on the heads and capstans, causing degraded high-
frequency characteristics, volume drop, or degraded recording and
erasure performances.
To prevent this, clean the heads, etc., periodically as follows.
1. Turn the power off.
2. Open the cassette holder by pressing the EJECT button.
3. As shown in Figure 2, clean the parts which come in contact
with tape, including the heads, capstans, tape guides, pinch
wheels, etc., with a cotton swab soaked in head cleaning
solution.
Head Demagnetization
When a magnetized metallic objects (such as a screwdriver tip,
etc.) comes in contact with a head or capstan, or when the deck has
been used for a long period of time, the head may be magnetized
and noise may be generated. If the head is extremely magnetized,
the high frequencies in recorded tapes could even be erased.
To prevent this, demagnetize the heads and capstans periodically
(every 20 hours of use) using a commercially-available head de-
magnetizer. (For the operation, please refer to the instruction
manual supplied with your head demagnetizer.)
Caution:
Be sure to turn the power of the cassette deck off
before using a head demagnetizer.
CLEANING OF EQUIPMENAL SURFACES
The exterior finish of your unit will last indefinitely with proper care
and cleaning. Never use scouring pads, steel wool, scouring
powders or harsh chemical agents (e.g., lye solution), alcohol,
thinners, benzine, insecticide or other volatile substances, as these
will mar the finish of the equipment. Likewise, never use cloths
containing chemical substances. If the equipment gets dirty, wipe
the external surfaces with a soft, lint -free cloth.
If the equipment becomes heavily soiled:
-
dilute some liquid soap in water, in a ratio of one part detergent
to six parts water
-
dip a soft, lint free cloth in the solution and wring the cloth out
until it is damp
-
wipe the equipment with the damp cloth
-
dry the equipment by wiping it with a dry cloth.
REPAIRS
Only the most competent and qualified technicians should be
allowed to service your unit. Marantz and its factory trained
warranty station personnel have the knowledge and special equip-
ment needed for repair and calibration of this precision instrument.
In the event of difficulty, call the toll-free telephone number listed
on the face of the warranty to obtain the name address of the
Marantz Authorized Service Center nearest you. In many cases,
the dealer where you purchased your Marantz unit may be equipped
to provide service. Please include the model and serial number of
your unit together with a copy of your purchase receipt and a full
