Care And Maintenance - Marantz PMD510 User Manual

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
5). It is possible to restore the recording capability of either side of
the cassette by covering the opening with clear adhesive tape (See
Figure 6).
ENHANCED REMOTE CONTROL OPERATIONS
Remark
To use a remote controller, either an infra Red remote control and
receiver or a wired remote control must be connected to the RC 5
Remote IN jack on the back of the unit.
Simultaneous (Parallel) Recording
Check to insure that both wells are in REC PAUSE mode after
pressing the A+B REC button on the front of the unit. The unit will
start recording when a PLAY command from the remote controller
has been received. During the REC mode, the unit can be placed
into a REC PAUSE mode by sending a PAUSE command from the
remote controller and started again by a PLAY command from the
remote controller. Pressing the STOP button on the front of the
unit or sending a STOP command from the remote controller will
cancel this operation.
Normal Speed Dubbing
Check to insure that well B is in REC PAUSE mode after pressing
the NORM DUBB button on the front of the unit. The unit will start
normal speed dubbing when a PLAY command from the remote
controller has been received. Pressing the STOP button on the
front of the unit or sending a STOP command from the remote
controller will cancel this operation
Note: The addition of this feature will allow the use of multiple units
for duplication when connected as follows: Unit 1, well A is
the source and Unit 1, well B as the duplication well #1 (in
other words Normal Speed Dubbing mode.). Additional
units can be connected to act as additional duplication wells
(See "Functions of Connecting Several Units").
Functions of Connecting Several Units
Several units an be controlled vie the REMOTE torminaic. Connect
all the units to be controlled by connecting the remote controller
output to the REMOTE IN of the first unit and the REMOTE output
of the first unit to the REMOTE IN of the second unit and so on.
Under this condition it is possible to control all of the units whether
they are set for simultaneous (parallel) recording and/ or normal
speed dubbing modes: assuming that the audio signals are directly
connected to each unit.

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
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.
Remove the cassette holder door by sliding it upward.
3. As shown in Figure 7, 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 EQUIPMENT EXTERNAL 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
description of what you feel is abnormal in its behavior.
