this equipment. It is strongly recommended that you follow the listed guidelines in
order to pre vent possible damage or loss of hea ring:

ESTABLISH A SAFE SOUND LEVEL

• Over time your hearing will ad apt to continuous loud sounds and will give the

impression that the volume has in fact been reduced. What seems normal to
you may in fact be harmful. To guard against this BEFORE YOUR HEARING
ADAPTS set the volume at a low level.

• Slowly increase the level until you can hear comfortably and clearly and without

distortion.

• Damage to your hearing is accumulative and is irreversible.

• Any ringing or discomfort in the ears indicates that the volume is too loud.

Once you have established a comfortable listening level, DO NOT INCRE ASE TH E
SOUND LEVEL FUR THER.

The following list of typical sound levels may assist you in recognizing just how loud
you have set the volume level.

SUPER ANTI-SKIP OPERATION

This player incorporates a superior electronic anti-skip circuit which prevents
interruption of the sound output when the unit is subjected to shock,
vibration or rolling during disc playback. If in use the player is likely to be
subjected to shock, vibration or rolling ( i.e. while walking or if used in a vehicle )
press the Super ASP button to provide uninterrupted playback.
When the Super ASP butto n is pre ssed in the play m ode the disp lay w ill sho w
and the function is initialised. When shows in the display the data buffer is
full.

Super ASP Indicator Super ASP Indicator Super ASP Indicator

The sound will mute for approximately 1 second while the buffer fills. Once
filled the buffer will give approximately 60 seconds of protection against
interruption of sound output. If t he player is subjected to shock or rolling of
over 60 seconds duration some interruption of sound output will occur. This
is normal and to be expected and t he sound will resume once the player
has stabilized from t he shock or rolling distu rbances.

To turn this function off press the Super ASP button.

Notes:

1. When using the Super ASP function the battery power consumption increases
because the disc rotates faster than normal and the dynamic menory is
active.

2. While the Super ASP function provides for continuous sound output
when the unit is subjected to continuous shock, vibration or rolling it will not
correct errors arising from the use of defective, scratched or dirty discs.

3. When powering the player solely from batteries, only use the Super ASP
function where necessary to preserve battery life.
