Using other functions
To minimize skipping (ESP2)
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 ESP2 (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 ESP2 provides excellent protection
against skipping, it will not prevent skipping
while jogging or running.
Press ESP.
