About lead free solder /
All of the P.C.B.s installed in this unit and solder joints are
soldered using the lead free solder.
Among some types of lead free solder currently available,
it is recommended to use one of the following types for
the repair work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
As the melting point temperature of the lead free solder
is about 30°C to 40°C (50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable
to each solder.
they can be exploded by improper handling. Observe the
following precautions when handling or replacing lithium
batteries.
• Leave lithium battery replacement to qualified service
personnel.
• Always replace with batteries of the same type.
• When installing on the PC board by soldering, solder
using the connection terminals provided on the battery
cells. Never solder directly to the cells. Perform the
soldering as quickly as possible.
• Never reverse the battery polarities when installing.
• Do not short the batteries.
• Do not attempt to recharge these batteries.
• Do not disassemble the batteries.
• Never heat batteries or throw them into fire.
Lithium batteries are dangerous because

WARNING: Laser Safety
This product contains a laser beam component. This component may emit invisible, as well as visible radiation,
which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must
be used during servicing of the unit.
1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm/1 feet
away from the laser pick-up unit at all times. Do not stare at the laser beam at any time.
2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.
3) CAUTION: Use of controls, adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
NS-BP110/NS-BP100
CRX-330/
Laser Emitting conditions:
1) When the Top Cover is removed, and the STANDBY/ON SW is turned to the “ON” position, the laser component will
emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate
through the lens of the laser pick-up unit. Do not attempt any servicing during this period!
If no disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any
laser emissions.
2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factory
prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this
manual. Adjustment of this control can increase the laser emission level from the device.

Warning for power supply
The primary side of the power supply carries live mains voltage when the player is connected to the mains even
when the player is switched off !
This primary area is not shielded so it is possible to accidentally touch copper tracks and/or components when servicing
the player.
Service personnel have to take precautions to prevent touching this area or components in this area.
Note:
The screws on the DVD mechanism may never be touched, removed or re-adjusted.
Handle the DVD mechanism with care when the unit has to be exchanged!
The DVD mechanism is very sensitive for dropping or giving shocks.

■ PREVENTION OF ELECTROSTATIC DISCHARGE
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are
called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect
transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence
of component damage caused by electro static discharge (ESD).
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD
on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging
ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as
aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD protect-
ed)” can generate electrical charge sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it.
(Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil
or comparable conductive material).
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective
material to the chassis or circuit assembly into which the device will be installed.
CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as
brushing together of your fabric clothes or lifting of your foot from a carpeted floor can generate static electricity (ESD)
sufficient to damage an ES device).
Grounding for electrostatic breakdown prevention
1. Human body grounding.
Use the antistatic wrist strap to discharge the static electricity from your body.
2. Work table grounding.
Put a conductive material (sheet) or steel sheet on the area where the optical pickup is placed and ground the sheet.
Caution:
The static electricity of your clothes will not be grounded through the wrist strap. So take care not to let your clothes touch
the optical pickup.
