About CD-Rs/CD-RWs
This CD player can play CD-Rs/CD-RWs
recorded in the CD-DA format*, but playback
capability may vary depending on the quality
of the disc and the condition of the recording
device.
* CD-DA is the abbreviation for Compact Disc
Digital Audio. It is a recording standard used
for the Audio CDs.
When closing the lid of the CD player
with the power supply attached
While the “disc” flashes in the display, the CD
starts rotating and will stop after the CD
player reads the disc information. This helps to
shorten the waiting time before playback
starts.

Do not touch the surface.

Using other functions
To maximize the skip protection
performance (ESP MAX)
The typical ESP (Electronic Shock Protection)
function minimizes skipping by using a
buffer memory that stores music data and
plays it back in the event of a shock.
The ESP MAX system is an extremely
sophisticated technology. Due to the light
weight and improved anti-shock
characteristics of the optical block, this system
recovers from the skipping much quicker
than conventional technology such as ESP or
ESP
2
.*
* Although ESP MAX provides excellent
protection, skipping may occasionally occur.
Set ESP to “ON.”
The ESP indication appears.
To release the ESP MAX function, set ESP to
“OFF.”
Notes
• Playing may stop when the CD player gets a
strong shock even with the ESP MAX function
on.
• You may hear a noise or sound may skip:
— when listening to a dirty or scratched CD,
— when listening to an audio test CD,
— when the player receives continuous shock or
— when using poor-quality CD-Rs/CD-RWs or
if there is a problem with the recording
device or application software.
