frequency, the output signal from the DIGITAL OUT (OPTICAL) jack is converted to 48 kHz sampling frequency.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer:

1. Check the area of your repair for unsoldered or poorly-sol-dered

connections. Check the entire board surface for solder splashes

and bridges.

2. Check the interboard wiring to ensure that no wires are "pinched"

or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transis-

tors, that were installed during a previous repair. Point them out

to the customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs

of deterioration. Point them out to the customer and recom-

mend their replacement.

5. Check the line cord for cracks and abrasion. Recommend the

replacement of any such line cord to the customer.

6. Check the B+ voltage to see it is at the values specified.

7. Check the antenna terminals, metal trim, "metallized" knobs,

screws, and all other exposed metal parts for AC leakage.

Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and

from all exposed metal parts to any exposed metal part having a

return to chassis, must not exceed 0.5 mA (500 microamperes).

Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA

WT-540A. Follow the manufacturers' instructions to use these

instruments.

2. A battery-operated AC milliammeter. The Data Precision 245

digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a VOM

or battery-operated AC voltmeter. The "limit" indica-tion is

0.75V, so analog meters must have an accurate low-voltage scale.

The Simpson 250 and Sanwa SH-63Trd are ex-amples of a pas-

sive VOM that is suitable. Nearly all battery operated digital

multimeters that have a 2V AC range are suit-able. (See Fig. A)

WARNING!!

WHEN SERVICING, DO NOT APPROACHTHE LASER EXIT

WITHTHE EYE TOO CLOSELY. IN CASE IT IS NECESSARY

TO CONFIRM LASER BEAM EMISSION, BE SURE TO

OBSERVE FROM A DISTANCE OF MORE THAN 25 cm

FROM THE SURFACE OF THE OBJECTIVE LENS ON THE

OPTICAL PICK-UP BLOCK.

Following Discs

The "DVD VIDEO" logo is a trademark.

Region code

Your player has a region code printed on the

back of the unit and will only play DVDs

labeled with identical region codes.

DVDs labeled

will also play on this

player.

If you try to play any other DVD, the

message "Playback prohibited by area

limitations." will appear on the TV screen.

Depending on the DVD, no region code

indication may be labeled even though

playing the DVD is prohibited by area

restrictions.

· All CD-Rs/RWs other than music and VCD

format CD-Rs/RWs

· Data part of CD-Extras

· DVD-ROMs

· DVD Audio discs

· DVD-RWs recorded in video recording

format (VR mode)

· HD layer on SACDs

Also, the player cannot play the following

discs:

· A DVD with a different region code (page

78).

· A disc recorded in a color system other than

NTSC, such as PAL or SECAM. (This

player conforms to the NTSC color

system.)

· A disc that has a non-standard shape (e.g.,

card, heart).

· A disc with paper or stickers on it.

· A disc that has the adhesive of cellophane

tape or a sticker still left on it.

Note

Some CD-Rs or CD-RWs cannot be played on this

player depending upon the recording quality or

physical condition of the disc, or the characteristics of

the recording device.

Furthermore, the disc will not play if it has not been

correctly finalized. For more information, see the

operating instructions for the recording device.

Note on playback operations of DVDs

and VIDEO CDs

Some playback operations of DVDs and

VIDEO CDs may be intentionally set by

software producers. Since this player plays

DVDs and VIDEO CDs according to the disc

contents the software producers designed,

some playback features may not be available.

Also, refer to the instructions supplied with

the DVDs or VIDEO CDs.

Notes about the Discs

On handling discs

· To keep the disc clean, handle the disc by its

edge. Do not touch the surface.

· Do not expose the disc to direct sunlight or

heat sources such as hot air ducts, or leave

it in a car parked in direct sunlight as the

temperature may rise considerably inside

the car.

· After pressing

A on the player to eject the

disc, do no leave the disc as it is. Remove it

completely from the player.

· After playing, store the disc in its case.

· If glue is present on the outer edge of the

disc, wipe the edge of the disc with the side

of a pen or pencil so that the glue is spread

evenly along the edge before inserting the

disc into the player. Be sure not to touch the

playback side of the disc when wiping the

edge.

· If burrs remain on the outer edge of the

disc, remove them by rubbing with the side

of a pen or pencil. If burrs are not removed,

discs may not load properly into the player,

or fragments of plastic adhering to the

playback side of the disc may cause

skipping in the sound.

On cleaning

· Before playing, clean the disc with a

cleaning cloth. Wipe the disc from the

center out.

· Do not use solvents such as benzine,

thinner, commercially available cleaners, or

anti-static spray intended for vinyl LPs.
