Precaution to be taken when replacing and servicing the laser pickup.
The following precautions must be observed during servicing to protect your eyes against exposure to the laser.
Warning of possible eye damage when repairing:
If the AC adaptor or batteries are connected when the top housing (disc cover) of the unit is removed, and the PLAY key is
pressed, the laser will light up during focus access (2-3 seconds). (Fig. 2-1) During the operation, the laser will leak from the
opening between the magnetic head and the mechanical chassis (Fig. 2-2). In order to protect your eyes, you must not look
at the laser during repair. Before repairing be sure to disconnect the AC adaptor and remove the batteries.
Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class 1 Requirements.
However, the following precautions must be observed during servicing to protect your eyes against exposure to the laser beam.
(1)Whenthecabinet has beenremoved,the power isturnedonwithout a compactdisc,and the Pickupisona position outerthan
the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.
(2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to
shipping.
(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
(4) Under no circumstances look directly into the Pickup Lens at any time.
(5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result in
hazardous radiation exposure.

PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
"All PWBs" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and
service manuals. The alphabetical character following LF shows the type of lead-free solder.
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free wire solder
WhenfixingthePWBsolderedwiththelead-freesolder,applylead-freewiresolder.Repairingwithconventionalleadwiresolder
may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 °C, we recommend you to use a
dedicatedsoldering bit,ifyouarenotfamiliarwithhowtoobtainlead-freewiresolder orsoldering bit,contact ourservicestation
or service branch in your area.
3. Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 °C which is higher than the conventional lead solder by 40°C,
and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of
time. However, Since the land may be peeled off or the maximum heat-resistance temperature of parts may be exceeded,
remove the bit from the PWB as soon as you confirm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corrected. Make sure to turn on and off the
power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use
of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.

•When the STOP button is pressed while the REC menu appears, or
in the REC mode or continuous record mode, the mode changes to
the TEST mode stop state.
•Wheneverthe MENUbutton ispressed in theREC menu, thetarget
address changes as follows.

When the PLAY button is pressed while a target address is dis-
played, continuous playback is performed after searching that
address.
•Whenever the REC button is pressed in the REC mode target
address is displayed, the digit which is changed by the VOLUME +/
