NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
Never look into the laser diode emission from right above when
checking it for adjustment. It is feared that you will lose your sight.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
Notes on chip component replacement
•Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged by heat.

Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 ˚C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 ˚C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
MP3 files
Notes on CD-Rs (recordable CDs)/
CD-RWs (rewritable CDs)
•Some CD-Rs/CD-RWs (depending on the
equipment used for its recording or the
condition of the disc) may not play on this
unit.
•You cannot play a CD-R/CD-RW that is not
finalized*.
•You can play MP3 files recorded on CDROMs, CD-Rs, and CD-RWs.
* A process necessary for a recorded CD-R/CD-RW
disc to be played on the audio CD player. Notes

Cautions on installation of the
monitor XVM-R70
• Installing the monitor
requires technical
expertise.
The monitor should be
installed by a qualified
technician or service
personnel.
• If you try to install the
monitor by yourself, do
it properly, referring to
the installation and
connection diagrams in
this installation/
connection manual.
Improper installation
may result in fire or
electric shock.
• Before installation, be
sure to turn the ignition
key switch to the OFF
position or take the key
out. Installing the
monitor with the
ignition key switch ON
may cause battery drain
or a short circuit.
• Do not damage any
pipes, tubes, the fuel
tank or electric wiring
when installing the
monitor. This can cause
a fire. If you drill a hole
in car panels, make sure
that any hidden car
parts will not be
damaged.
• Do not use any nuts or
bolts for safety devices
such as steering linkage,
fuel supply or braking
systems. This can cause
a fire or an accident.
• Take care to prevent
cords and wires from
getting tangled or
crimped in the moving
portion of a seat rail.

Cautions before connection
• The products are designed for negative ground 12 V
DC operation only.
• Before making connections, turn the car ignition off to
avoid short circuits.
• Connect the yellow and red power input leads only
after all other leads have been connected.
• Be sure to connect the red power input lead to the
positive 12 V power terminal which is powered when
the ignition switch is in the accessory position.
• Run all ground wires to a common ground point.
• The use of optical instruments with the player will
increase eye hazard.
• Use of controls adjustments or performance of
procedures of other than those specified herein may
result in hazardous radiation exposure.
Notes on the power supply cord (yellow)
•When connecting the player and the monitor in
combination with other stereo components, the
connected car circuit’s rating must be higher than the
sum of each component’s fuse.
•When no car circuits are rated high enough, connect
the products directly to the battery.
Connection diagram (4)
1 To a metal surface on the car
First connect the black ground lead, then
connect the yellow and red power input leads.
2 To the +12 V power terminal which is
powered at all times
Be sure to connect the black ground lead to a
metal surface of the car first.
3 To the +12 V power terminal which is
powered when the ignition switch is in
the accessory position
Be sure to connect the black ground lead to a
metal surface of the car first.
Caution
If your car has no accessory position on the
ignition key, be sure to insulate and do not
connect the ACC lead (red) to anywhere. If you
connect the ACC lead according to the Operating
Instructions, it will cause the battery drain.
4 To POWER REMOTE IN of an optional
power amplifier
This connection is for amplifiers.
Notes
• If there is no accessory position, connect to the +12
V power (battery) terminal which is energized at
all times. Be sure to connect the black ground lead
to a metal surface of the car first.
• If you use the R (audio right)/L (audio left)/V
(video) output on the rear of the player, the
output level of video will be halved.
Cautions on installation of the
player MV-101
• Choose the mounting location carefully.
• Avoid installing the player in places:
— subject to temperatures below – 30 °C (– 22 °F) or
above 45 °C (113 °F)
— subject to direct sunlight.
— subject to heat;
Keep all products away from nearby hot vehicle
components that heat up over time such as hoses,
high current wires, and braking system
components. Make sure to leave enough room for
ventilation of openings and slots to protect from
over heating.
— near heat sources such as heaters.
— exposed to rain or moisture.
— exposed to excessive dust or dirt.
— subject to excessive vibration.
— where the fuel tank might be damaged by the
tapping screws.
— where wire harnesses or pipes might be under the
place.
— where the screws or the player itself might damage
the spare tire, tools, or other equipment in or
under the trunk.
— where the player might interfere with with the
normal movements of the driver.
— under the floor carpet, as the heat dissipation from
the player might damage the carpet.
• Be sure to use only the supplied mounting hardware
for a safe and secure installation.
• Use only the supplied screws.
• Make holes of ø 3 mm (
there is nothing on the other side of the mounting
surface.
• Do not install the player on inclined places. Install the
player on a level surface.
• Install the player just horizontally or vertically.
