    3. Do not place the disc on a glass surface. It may damage the disc. If this happened,please use a new testing disc adjust DVD player precision.

    6.3 Notes

    PLEASE READ ALL NOTES GIVEN IN THIS MANUAL.

    Locate Place the unit on a firm, flat surface. Do not place in a high temperature (upwards of 40 ) or high wet (upwards of 80 percent) area.

    Do not place in an area with a lot of dust. Keep away from direct sunlight &domestic heating equipment. Do not fall any objects into the unit. Care should be taken so that liquids are not spilled into the unit openings.

    Such situations could result in fire or electrical shock.

    Keep the DVD video player away from any magnetic articles such as speaker etc.

    Superposition Please place the DVD player horizontally. Do not place a heavy object

    (amplifier, receiver) on it. The object may fall, causing serious personal injury

    or death.

    This unit should be situated away from heat source, such as amplifiers, radiators,stoves or any other units producing heat.

    CondensationLens could be moistening in these cases.

    Turn on heater shortly, In a very wet room, Move the player from a cold environment to a heat environment quickly.

    Being moisture inside the play could operate normally. Please turn on power and

    wait about an hour for drying the moisture.
