Introduction

Thank you for purchasing an AVI Laboratory series CD player. As the name
implies, it is a precision instrument, meticulously hand built and tested and, given
the right circumstances, will produce the best sound quality that current
technology will allow.

We recommend that before you use your new CD player, you carefully read the
instruction manual. If you are familiar with the way the machine works before
you start, you are much less likely to encounter problems.

Installation

The Laboratory Series Integrated amplifier has been designed so that your CD
player can be put on top of it provided it is well ventilated. In cupboards where
air cannot circulate it would be best to put them side by side or, if you are using
another make of power amplifier that gets warm or even hot in use, then do not
put the CD player on top of it, as high temperatures can damage the laser
mechanism.

Use good quality, screened coaxial phono-to-phono leads, avoiding ones that lock
and always makes sure that force applied to plug in or remove leads is directly in
line with the sockets. This is to minimise the risk of damage.

AVI products are extremely reliable but we do occasionally get units back for
repair because the phono sockets have been damaged. This is because many
people believe that cables can be used to fine tune the system or overcome some
problem with sound quality. Usually their problems are quite severe and cable will
not make sufficient of a difference. The biggest differences are caused by room
acoustics and to a lesser extent, loudspeakers. If you are in trouble, we may well
be able to help so please get in touch.

As a general rule it is not a good idea to remove replace cables whilst the system
is switched on. The pops, clicks and hums that can occur may damage
loudspeakers especially if you amplifier is quite powerful.

Instructions for use

Make sure everything is correctly connected throughout the entire system before
switching on the mains using the button to the right rear side of the machine. The
machine is now ready to use.

Pressing the standby button will switch off the display to indicate that the
machine cannot be used.

To operate the machine (once it is out of standby), press the drawer open button,
insert the CD, text uppermost, and press either the drawer close or play button.
Pressing the play button will start it and closing the drawer will allow it to indicate
the number of tracks and the length of the CD but not to play until the play
button is pressed.

If you wish to play a track other than the first, then press play, wait until track
one is playing and then press the next button to cycle through the tracks to reach
the one you want. If you have gone too far, then press the previous button to get
back to where you want.

Playability Issues

Some of the major record companies have decided to ignore Red Book standards
that are intended to ensure complete compatibility between Discs and Machines
made anywhere in the World and incorporate Copy Protection Software in the
CD’s that they are producing. These CDs are not Red Book Compliant. The Record
Companies describe them as Red Book “Comparable” YUK!

Retailers cannot advertise its presence but have to tell you if asked. The fact that
the “Compact Disc Digital Audio” Logo is missing is an indication that Copy
Protection is present.

Copy protected Discs should not carry the “Compact Disc Digital Audio” Logo but
should carry an indication of protected content.

Copy Protected discs will not play in all Red Book Standard Audio CD players.

You AVI CD player is a Red Book compliant machine and may well not play some
Copy Protected Discs and there is nothing we can do about it. If your machine
plays the majority of Compact Discs in your collection then it is unlikely to be
faulty.

CDR's can be used as a guide to the condition of the laser. They are less
reflective and are less likely to play if it is either faulty or reaching the end of its
life.

Those interested in greater detail should search “CD Playability” on the Internet.

From the handset

Press disc button to open or close drawer.

Press to begin playing from track one

Press track number and then play to select a required track if you do not wish to
start at the beginning.

Press the scan button to hear the first few seconds of each consecutive track.

To program your own selection of tracks, press required track number followed by
program and once all required tracks have been entered, press play.

Press the time button to show elapsed or time remaining of entire CD or track
playing.

To scan through a track press the double arrow forwards or rearwards and to
speed up the process, press the fast button.

If you need to repeat a small portion of a particular track, press A to start the
process and B at the end of the bit required.

Press shuffle and play to play all the tracks in random order.

To move forward one track, press the single arrow pointing right and to move
back to the beginning of the track playing, press the single arrow left. Pressing it
a second time will move you to the beginning of the previous track.

If you wish to repeat a single track, press the number required, press repeat and
then play.

Pressing the pause button will stop play and hold the position on the CD until
pause or play is press to restart playing.

Pressing stop stops the machine.

Pressing play starts again from the beginning.

Track/Time Display Selection

If a CD is playing then pressing the time button on the handset issued with the
CD player (not the system handset which has more limited facilities) will change
the display mode in the following sequence:

Track number
Elapsed time of current track
Elapsed time of whole CD
Time left on CD
Then back to track number.

If playing has stopped the machine will indicate total number of tracks and total
time of CD.

During program play, whenever the CD player changes track, the display will
show the new track number and the letter P, indicating, program play for a
couple of seconds before returning to the selected mode.

IF YOU HAVE A LABORATORY SERIES INTEGRATED AMP

It will come with a One for All handset that can be programmed to operate your
CD player just follow the instruction manual for the handset and use the code
number for a Philips CD player. The One for All can also be programmed to
operate the volume control on the amplifier whilst controlling the CD Player.

Rear Panel connections and controls

In normal use your AVI Laboratory Series CD player can be left in standby,
although there is no advantage in doing so. We recommend that it be turned off if
it is not going to be used for some time. The power switch is to the rear right
hand side of the unit.

In addition to the output phonos your CD player also has both types of digital
output, Toslink optical and a phono socket for an electrical output.

Always switch everything off before removing or replacing connectors.

Laser assemblies are susceptible to damage from excessive heat, shock and static
electricity so, once it is unpacked, handled it gently, make sure it is properly
earthed and keep it away from anything that gets hot.

Safety Information

If the mains fuse blows make sure that the replacement is the same and as
specified below:

Fuse rating:- 110V/120V T500mAL

220V/230V T250mAL

Operate on AC mains only

The unit must be earthed

Always disconnect mains supply before making connections

If the mains lead is damaged, replace it with a good quality one of the same
specifications or better.

If you suspect that liquid has been spilled onto the unit, do not switch it on or
switch off immediately and return it for service.

Avoid installing anywhere hot, e.g. direct sunlight, radiators or hot amplifiers.

Avoid high levels of humidity.

Avoid dusty environments.

There are no user serviceable components inside the unit.

Cleaning

Use a soft damp cloth

Do not use cleaners or solvents of any kind

Do not use an abrasive cloth

Disconnect mains whilst cleaning

NB. Do not attempt to clean the laser. I you suspect problems, the unit should be
returned for service by the factory. That is the only way to ensure the
performance is as it should be.

Care of Compact discs

Compact discs can be very frustrating and not play when they appear in perfect
condition whilst others that are covered in scratches give no problems
whatsoever.

The smallest scratch in the right place can stop a CD from playing as can a
smudge or a fingerprint.

Avoid touching the surfaces of the disc and keep it in its jewel case when not in
use.
