DEAR CUSTOMER:
Thank you for purchasing this car audio product.
Selecting fine audio equipment such as the unit you have just purchased is only the start
of your musical enjoyment. Now it is time to consider how you can maximize the fun and
excitement your equipment offers.
We hope you get the most out of your equipment by playing it at a safe level.
One that lets the sound come through loud and clear without annoying blare or distortion,
and, more important, without affecting your sensitive hearing.
Sound can be misled. Over time your hearing " comfort level " adapts to higher volumes
of sound. So what sounds " normal " can actually be loud and harmful to your hearing.
Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
Start your volume control at the lowest setting , then slowly increase the sound until you can
hear it comfortably and clearly, and without distortion we want you listening for a lifetime.
Once you have established a comfortable sound level:
Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing damage or loss in the
future. After all, we want you listening for a lifetime.

We recommend that you familiarize yourself with the functions and their operation by
reading through the manual before you begin using this product. In this operation manual,
the Basic Operation for each sound source is outlined at the beginning of its explanation,
covering simple operation for that source, such as merely playing music.
Remark:
In addition to normal audio CD, this unit can play CD-R and CD-R/W disc that contain
audio tracks as well; however, depending on the conditions of the recording equipment,
recording program or the CD-R as well as CD-R/W disc itself, some CD-R or CD-R/W
may not play.
When making music CD with CD-R or CD-R/W disc, too high recording speed may
result in poor signal quality and therefore, it is recommendable to select 24x or lower
speed for CD-R recording and 4x or lower speed for CD-R/W recording.
