5.2 S t oring and Handling Test Discs

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

Please 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.

Decode Amplifier

Speaker

3. Do not place the disc on a glass surf ace. It may damage the disc. If this

happened, please use a new testing disc adjust DVD player precision.

5 .3 No tes

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 35 ) or high wet

(upwards of 90 percent) area.

● Do not place in an ar ea with a l ot 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.

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.
