PROTECT YOUR FURNITURE
This system is equipped with non-skid rubber ‘feet’ to prevent the product from moving when you
operate the controls. These ‘feet’ are made from non-migrating rubber material specially
formulated to avoid leaving any marks or stains on your furniture. However certain types of oil
based furniture polishes, wood preservatives, or cleaning sprays may cause the rubber ‘feet’ to
soften, and leave marks or a rubber residue on the furniture. To prevent any damage to your
furniture we strongly recommend that you purchase small self-adhesive felt pads, available at
hardware stores and home improvement centers everywhere, and apply these pads to the
bottom of the rubber ‘feet’ before you place the product on fine wooden furniture.
DEAR JENSEN® CUSTOMER
Selecting fine audio equipment such as the unit you've just purchased is only the start of your
musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your
equipment offers. This manufacturer and the Electronic Industries Association's Consumer
Electronics Group want you to 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 blaring or distortion and,
most importantly, without affecting your sensitive hearing.
Sound can be deceiving. 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 a low setting.
• Slowly increase the sound until you can hear it comfortably and clearly, and without
distortion.
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 Want You Listening For a Lifetime
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment.
Since hearing damage from loud noise is often undetectable until it is too late, this
manufacturer and the Electronic Industries Association's Consumer Electronics Group
recommend you avoid prolonged exposure to excessive noise.
Customer's Record:
The serial number of this product is found on its back cover. You should note the serial
number of this unit in the space provided as a permanent record of your purchase to aid
in identification in the event of theft of loss.
