1 ABOUT LEAD FREE
SOLDER (PbF)

Distinction of PbF PCB:

PCBs (manufactured) using lead free solder will have a PbF
stamp on the PCB.

Caution :

- Pb free solder has a higher melting point than standard
solder; Typically the melting point is 50 » 70°F (30 »
40°C) higher. Please use a soldering iron with
temperature control and adjust it to 700 t 20°F (370 :
10°C). In case of using high temperature soldering iron.
please be careful not to heat too long.

0 Pb free solder will tend to splash when heated too high
(about 1100°F/600°C)

- This lead free solder will be used for the products after
serial No. 1,000,001.

2 FEATUERS

3 LASER PRODUCTS

CAUTION:
This product utilizes a laser diode with the unit turned "on",
laser radiation is emitted from the pickup lens.
Laser radiation from the pickup lens is safety level, but be
sure the followings:
1. Do not disassemble the optical pickup unit, since
radiation from exposed laser diode is dangerous.
2. Do not adjust the variable resistor on the pickup unit.
It was already adjusted.
3. Do not look at the focus lens using optical instruments.
4. Recommend not to look at pickup lens for a long time.

DANGER! Invisible laser radiation when open.
Avoid direct exposure to beam.

Deck Ass'y (Upper Side)

Caution

This Product utilizes a laser.

Use of controls or adjustments or performance of
procedures otherthan those specified herein may
result in hazardous radiation exposure.

4 REPLACEING THE FUSE

Use fuses of the same specified rating (15A). Using different
substitutes or fuses with higher ratings. or connecting the
product directly without a fuse. could cause fire or damage to
the stereo unit.
