Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

Listening Safely
To protect your hearing, follow these guidelines when you use headphones. � Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level. � Do not listen at extremely high volume levels. Extended highvolume listening can lead to permanent hearing loss. � Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.
CONNECTING HEADPHONES
To listen to your Concertmate 970 without disturbing others, you can connect a pair of 1/4-inch plug stereo headphones (not supplied). Your local RadioShack store sells a wide selection of headphones. To connect a pair of headphones, insert the headphones� 1/4-inch plug into the PHONES/OUTPUT jack on the back of the keyboard.
