CAUTIONUse of controls or adjustments or performance of procedures other than those specifi ed herein may result in hazardous radiation exposure.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic breakdown 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 fl exible board is easily damaged and should be handled with care.

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 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 SOLDERBoards requiring use of unleaded solder are printed with the lead free 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 MARKUnleaded 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 fl ow) 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.

This appliance isclaassifi ed as a CLASS 1LASER product. Thislabel is located on therear exterior.

NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused on the disc refl ective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.

Laser component in this product is capableof emitting radiation exceeding the limit forClass 1.

[FM Tune Level Check]

Procedure:1. Turn the power on.2. Input the following signal from Signal Generator to FM an-

tenna input directly. * Carrier Freq : A = 87.5 MHz, B = 98 MHz, C = 108 MHz Deviation : 75 kHz Modulation : 1 kHz ANT input : 35 dBu (EMF)

Note: Please use 75 ohm “coaxial cable” to connect SG and the set. You

cannot use video cable for checking. Please use SG whose output impedance is 75 ohm.

3. Set to FM tuner function and tune A, B and C signals.4. Confi rm “TUNED” is lit on the display for A, B and C sig-

nals.

The mark of “TUNED” means “The selected station signal is received in good condition.”

UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead free 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 MARKUnleaded 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 viscous (sticky, less prone to fl ow) 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.
