Ŷ Locate
Ɣ Place the unit on a firm, flat surface.
Ɣ Do not place in a high temperature (upwards of 40
) or high wet
(upwards of 80 percent) area.
Ɣ Do not place in an area with a lot of dust.
Ɣ Keep away from direct sunlight &domestic heating equipment.
Ŷ Do not fall any objects into the unit.
Ɣ Care should be taken so that liquids are not spilled into the unit openings.
Such situations could result in fire or electrical shock.
Ɣ Keep the DVD video player away from any magnetic articles such as speaker etc.
Ŷ Superposition
Ɣ Please place the DVD player horizontally. Do not place a heavy object
(amplifier, receiver) on it. The object may fall, causing serious personal injury
- 16 -
or death.
