6.2 Storing and Handling Test Discs

care for storing and using it.

1. Do not place the disc on worktable directly after using.

2. Do not store discs in places subject to direct sunlight or near heat sources.

It is important for a DVD testing disc keeping its surface precise. Please

- 20 -

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

- 21 -

or death.

● This unit shou

ld be situated away from heat source, such as amplifiers, radiators,

stoves or any other units producing heat.

■ Condensation

Lens 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.
