6. Precaution of Laser Diode
ON :
This product utilizers a class 1 laser. Invisible laser radiation is
emitted from the optical pick up lens.
When the unit is turned on:
Wavelength : 662nm(DVD)/785nm(CD)
Maximum output radiation power from pick up : 100 W/VDE
Laser radiation from pick up unit is safety level, but be sure the
followings:
1. Do not disassemble the optical pick up unit, since radiation from
exposed laser diode is dangerous.
2. Do not adjust the variable resistor on the pick up unit. It was
already adjusted.
3. Do not look at the focus lens using optical instruments.
4. Recommend not to look at pick up lens for a long time.
7. 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 high temperature soldering iron. In case of the soldering
iron with temperature control, please set it to 700 ± 20°F (370 ±
10°C).
