REMOTE CONTROL SYSTEM

This is a convenient system which has been originated and developed by Philips. Before starting operation, connect the remote cable as shown on page 7. The followings are the brief explanation of its major performances:

Synchronized Recording Synchronized recording refers to the process in which the

DAT deck starts recording in synchronism with the CD player.

Please study these instructions carefully before starting to operate the unit, to use the unit correctly. We take no responsibility

for any problems resulting from misuse of this unit if it is operated, by methods other than those given in this manual.

On operating this unit: Since this unit incorporates a microprocessor which controls various functions, please read the description and cautions (notes) for each item carefully before use. If operated incorrectly, the required functions may not be per formed. In this case, turn the power OFF then turn it ON again and see if correct operation has become possible.

Important note for users in U.K.:

The U.K. version is not fitted with a mains plug. When fitting a mains plug to the mains lead note that the wires in the mains lead are coloured with the following code:

Blue = Neutral, Brown = Live.

As these colours may not correspond with the colour mark

ings identifying theterminals in your plug proceed as follows:

the Brown wire must be connected to the terminal which is marked with the letter L or coloured Red. The Blue wire must be connected to the terminal which is

marked with the letter N or coloured Black. Note: This apparatus must be protected by a 3 Amp Fuse if a 13 Amp plug is used or, if any other type of plug is used, by

a 5 Amp Fuse either in the plug or adapter or atthe distribution board. If in doubt consult a qualified electrician.

DO NOT CONNECT EITHER WIRE TO THE EARTH TERMINAL IN THE PLUG WHICH IS MARKED BY THE LETTER E OR BY

THE SAFETY EARTH SYMBOL OR COLOURED GREEN OR

GREEN-AND-YELLOW

CAUTIONS

1. Safety hints

1. Be sure to pull the plug, not the cord. (Fig. 1)

2. Do not handle the power cord with wet hands.

3. Do not damage the power cord. (Fig. 2)

4. if the deck is not to be used for an extended period, unplug

the power cord.

5. Do not remove the cabinet. To avoid electric shocks, do not

touch parts inside the deck. Consult a dealer for repairs.

6. Do not permit any liquids or objects to get inside the deck.

The deck could be damaged if water or flammable or metallic objects get inside.

Pull the plug when disconnecting the cord.

Note:

This diagram does not represent a U.K. mains plug.

Fig.1

5. Condensation

1. if condensation forms on the head drum, the heart of a DAT

unit, the tape may stick to the head drum and may be damaged.

2. Condensation may occur in the following cases:

• When the unit is moved from a cold place to a warm place,

• In a room immediately after its heating has been switched ON, or in a place where the deck is exposed to cold air from a cooler.

• In a place which is excessively humid.

3. When condensation could have occurred in the DAT deck

such as when it is moved from a cold place to a warm place, turn the POWER switch ON and leave it for about one hour before using it. When condensation is likely to occur, do not leave a cassette in the deck. It is recommended that you always remove cassette tapes from the deck when it is not in use.

• Use the deck where the ambient temperature is from 5°C(41°F)to35°C(95°F). When the deck is used in a cold place, condensation may occur more frequently.

6. Timer switch setting Set the TIMER switch to “REG” or "PLAY" v;hen performing timer recording or playback. At other times, be sure to set the TIMER switch to OFF.

Take care not to damage the power cord.

Fig. 2

2. Installation

1. Avoid placing the unit on or adjacent to an amplifier, to prevent

hum which is produced by some types of amplifiers. Move the unit to a place where it will not be affected by the amplifier.

Keep the unit as far as possible from a TV set.

2. Avoid installing the unit in a location subject to excessively

high temperatures (e.g. direct sunlight, near a heater, etc.),

excessive humidity, dust, vibrations or magnetic fields.

3. Cleaning the heads

If this unit is used for a long period of time, its heads will become

dirty. When they become excessively dirty, recording and

playback will not be satisfactory. Because of this, clean the heads every 30 hours of playing time with a cleaning cassette available

from your audio store.

Press the e/o REC and ► PLAY buttons then, after another 10 seconds, press the ■ STOP button.

REC OFF PLAY

TIMER

7. Heat radiation Be careful not to block the ventilation holes so that the tem perature inside the deck does not rise excessively. Do not install the unit in a badly ventilated place.

SELECTING THE AC SUPPLY VOLTAGE

When this deck is used in an area where the supply voltage is different from the preset voltage, reset the voltage selector to the correct position. Slide the voltage selector with a screwdriver so that the desired voltage marking is in the window.

4. Volume setting In DAT, digital signals are recorded and played back; because of this, it is difficult to set the appropriate volume using the level of noise as a reference. Do not raise the volume excessively even if the beginning of a tune seems quiet. Otherwise, when the level of the sound rises, it could damage the speakers or other equipment.

Caution: Disconnect supply cord before changing the voltage.

Used to designate the desired tune directly.

B START ID-WRITE button

Used to write a start ID.

B Tape operations buttons B DIGITAL PEAK button

Used to recall or reset the maximum value stored in the digital peak memory.

* Other control buttons have the same functions as those on

the front panel of the main unit.

Notes:

1. When the distance from which the remote control unit is

effective becomes shorter, the batteries are almost exhausted. Replace the batteries with new ones.

2. Be sure to use two “R03" batteries in the remote control.

Incorrect use of batteries may cause corrosion or an explosion.

• Insert the batteries into the battery compartment with correct

• Do not use old and new batteries together.

• When the unit is not to be used for an extended period of time, remove the batteries to prevent damage due to corrosion.

CONNECTIONS

• Do not switch the power on until aii connections are completed.

• Insert the plugs firmly: poor contact can cause noise.

1. Connection to stereo components

(Analog signal lines)

DAT deck

When RCA pin-plug cords are employed, always connect the white plug to the left channel terminal. This helps avoid reversed connections.

• When the stereo amplifier is not provided with DAT terminals,

refer to its instruction manual.

2. Remote cable connection for REMOTE

CONT.

• By connecting a remote cable, REMOTE CONT. functions

(synchro recording) can be performed.

' When making synchro recordings with a CD player, connect

the remote cable to the REMOTE CONT. jacks.

Connect the REMOTE CONT. jack of the deck to the REMOTE CONT. jack of the amplifier using the remote cable provided.

Note:

When installing this unit, leave an appropriate distance between

it and your stereo amplifier, tuner and television set. If they are

too close, noise (induced hum) may occur. We recommend that you use outdoor FM and TV antennas.

3. Connections to stereo components

(Digital signal lines)

• To transmit digital signais between the DAT deck and an amplifier with digital in/out terminals exclusively for DAT, use

the DIGITAL IN/OUT terminals on the rear panel of the deck.

For the transmission of digital signals, two types of cables can be used; COAXIAL (for electrical signals) and OPTICAL

DAT deck

(for optical signals). Either of these can be used for digital

signal transmission. With digital signals, only one cable is used for the transmission of both the left and right channel signals.

• OPTICAL connection Remove the caps from the OPTICAL terminals and connect

the DIGITAL OPTICAL IN/OUT terminals to the amplifier, etc. using exclusive optical fiber cables.

Note: Clean the tip of the plug of the optical cable before connecting it.

• Synchro recording with CD player

When making a synchro recording with a CD player, as well as connecting the optical fiber or coaxial cable, perform the following connections.

1. Connect the REMOTE CONT. terminals with the remote

cable. (See page?.)

2. Connect the OUTPUT terminal (analog) of the CD player and

the ANALOG IN terminal wi^i a RCA pin cord.

• Red light in the OPTICAL OUT terminal:

When the power is turned on, a red light appears inside the terminal. This is used to transmit the digital signal. Although

it is not dangerous even when it strikes the eyes directly, do not remove the cap covering the terminal when not in use.

Notes:

1. When a digital program is encoded with a “copy prohibit”

code (except in case of SCMS), it cannot be copied digitally. To copy such a program, perform analog

connection. (Refer to page 12.)

2. Never connect the digital coaxial cable to the analog input

terminals of an amplifier, etc. as this could seriously damage the amplifier.

3. When the OPTICAL terminals are used for digital connection,

check that the optional exclusive optical fiber cables can be

inserted into the terminals of the amplifier.

4. Do not bend optical fiber cable sharply. For details, refer to

its instructions.

5. When both the ANALOG and COAXIAL terminals of the DAT

deck are used for the connection of certain components (amplifiers, tuners, cassette decks, etc.), noise (induced hum) may occur. In this case, disconnect any unused IN/OUT terminals.

DAT CASSETTES

Concerning DAT cassettes

• Use cassette tapes with the DAT logotype shown here.

DgtaiAxtoTape

When a tape on which a recording has previously been made is used for recording, the previously recorded signals will be erased automatically, and the tape will contain only the new recording.

• DAT cassettes cannot be used upside down.

• DAT cassettes have a lid (cover) to prevent the accumulation of dust or dirt on the surface of the tape. Do not open this forcibly.

Cassette identification holes x 3

Rear of the cassette

Accidental erasure prevention hole (determines if recording is possible or not)

• DAT cassettes have sliding safety tabs to prevent accidental erasure. Be sure to open the tabs of cassettes containing important recordings which you want to protect against accidental erasure.

• DAT cassette shells are constructed so that the tape cannot be touched by accident.

Identification hole (for prerecorded music tapes)

Tape protection lid

Cautions on storage of DAT cassettes

• Do not leave cassettes in a place exposed to direct sunlight

or near a heater, etc.
