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.
Take 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 bottom. 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.
Model Number: JMC-180B Serial Number: ____________________
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.
