Preface
Thank you for purchasing this car audio product.
Please read this manual carefully before operating this car audio product.
Please keep this manual for future use. It will be helpful to you if you are encounter any
operational problem.
Selecting fine audio equipment is only the start of your musical enjoyment.
Now it is time to consider how to maximize the enjoyment you will get from
knowing how to work your new car stereo receiver.
We hope you enjoy using this product and encourage you to always listen at
a moderate, safe sound level to avoid any possible hearing damage or loss.
If you listen to excessively loud sound over time, your hearing can adapt to
higher volumes and what sounds "normal" to you may be quite harmful and
can cause you to have permanent hearing loss. So please practice "safe sound"
and always listen at moderate sound levels only.
Start with your volume control at the lowest setting, and slowly increase the level
until you can hear it comfortably and clearly, free from distortion.
Once you have established this comfortable sound level, leave it there.
