CONDENSATION
Moisture will form in the operating section of the player if the player is brought from cool surroundings into a
warm room or if the temperature of the room rises suddenly. When this happens, player's performance will
be impaired.
To prevent this, let the player stand in its new surroundings for about an hour before switching it on, or
make sure that the room temperature rises gradually.
Condensation may also form during the summer if the player is exposed to the breeze from an air conditioner. In such cases, change the location of the player.
HOW TO HANDLE THE LCD PANEL
• Do not press hard or jolt the LCD panel. It may cause the LCD panel glass to break and injury may occur.
• If the LCD panel is broken, make absolutely sure that you do not touch the liquid in the panel. This may
cause skin inflammation.
If the liquid gets in your mouth, immediately gargle and consult with your doctor. Also, if the liquid gets in
your eyes or touches your skin, consult with your doctor after rinsing for at least 15 minutes or longer in clean
water.

ABOUT LEAD FREE SOLDER (PbF)
Distinction of PbF PCB:
PCBs (manufactured) using lead free solder will have a PbF printing on the PCB.
(Please refer to figures.)
Caution:
Pb free solder has a higher melting point than standard solder;
•
Typically the melting point is 86°F~104°F(30°C~40°C) higher.
Please use a soldering iron with temperature control and adjust it to 650°F ± 20°F (350°C ± 10°C).
In case of using high temperature soldering iron, please be careful not to heat too long.
Pb free solder will tend to splash when heated too high (about 1100°F/ 600°C).
•
All products with the printed circuit board with PbF printing must be serviced with lead free solder.
•
When soldering or unsoldering, completely remove all of the solder from the pins or solder area,
and be sure to heat the soldering points with the lead free solder until it melts sufficiently.
Recommendations
Recommended lead free solder composition is Sn-3.0Ag-0.5Cu.
