Using other functions

To minimize skipping (ESP

2

)

The ESP (Electronic Shock Protection)
function minimize skipping by using a buffer
memory that stores music data and plays it
back in the event of a shock.
The new ESP

2

 (ESP Squared) system uses a

new DSP (Digital Signal Processor) which can
read and store music data more efficiently,
providing a level of continuous skip
protection not found in traditional buffer
memory units. This decreases the frequency
of sound skipping and the need to utilize the
buffer memory. Use this function when
listening in a car or while walking.*

* Although ESP

2

 provides excellent protection

against skipping, it will not prevent skipping
while jogging or running.

Press ESP.
The ESP indication appears.

To release the ESP function, press ESP again.

Notes

• Playing may stop when the player gets a strong

shock even with the ESP function on.

• You may hear a noise or sound skip when:

— listening to a dirty or scratched CD,
— listening to an audio test CD or,
— the player receives continuous shock.

• Sound may drop for a while if you press ESP

during play.
