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 inyour eyes or touches your skin, consult with your doctor after rinsing for at least 15 minutes or longer in cleanwater.
CONDENSATIONMoisture will form in the operating section of the player if the player is brought from cool surroundings into awarm room or if the temperature of the room rises suddenly. When this happens, player's performance willbe impaired.To prevent this, let the player stand in its new surroundings for about an hour before switching it on, ormake 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 condi-tioner. In such cases, change the location of the player.
25) Do not allow the product to output distorted sound for an extended period of time. It may cause speakeroverheating and fire.
26) When you use the headphones, keep the volume at a moderate level. If you use the headphones continu-ously with high volume sound, it may cause hearing damage.
27) Do not look into the opening of the disc slot or ventilation opening of the product to see the source of thelaser beam. It may cause eye damage.
28) Do not use a cracked, deformed, or repaired disc. These discs are easily broken and may cause seriouspersonal injury and product malfunction.
29) This reminder is provided to call the cable TV system installers attention to Article 820-40 of the NEC thatprovides guidelines for proper grounding and, in particular, specifies that the cable ground shall be con-nected to the grounding system of the building, as close to the point of cable entry as practical.

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 86F~104F(30C~40C) higher.Please use a soldering iron with temperature control and adjust it to 650F 20F (350C 10C).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 1100F/ 600C).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.
Distinction of PbF PCB:
RecommendationsRecommended lead free solder composition is Sn-3.0Ag-0.5Cu.
