CARE AND MAINTENANCE
CARING FOR CDS
Treat the CD surface with care. Although a CD lasts
indefinitely with normal use, we recommend the
following precautions:
• Handle a CD by its edge to avoid fingerprints, which
can prevent the CD changer’s laser beam from reading
the CD. CD cleaner kits are available at your local
RadioShack store.
• Keep the CD dry. A water drop can act as a lens and
affect the laser beam’s focus.
CARING FOR THE CD-9400
Your RCA CD-9400 Compact Disc Changer is an example
of superior design and craftsmanship. The following
suggestions will help you care for the CD changer so you
can enjoy it for years.
Keep the CD changer dry. If it gets wet, wipe it
dry immediately. Liquids can contain minerals
that can corrode the electronic circuits.
Handle the CD changer gently and carefully.
Dropping it can damage its circuit boards and
cases and can cause the changer to work
improperly.
Use and store the CD changer only in normal
temperature environments. Temperature
extremes can shorten the life of electronic
devices, damage batteries, and distort or melt
plastic parts.
Keep the CD changer away from dust and dirt,
which can cause premature wear of parts.
Wipe the CD changer with a damp cloth
occasionally to keep it looking new. Do not use
harsh chemicals, cleaning solvents, or strong
detergents to clean the CD changer.
Use only fresh batteries of the recommended
size and type in the remote control. Always
remove old or weak batteries. They can leak
chemicals that destroy electronic circuits.
Modifying or tampering with your CD changer’s internal
components can cause a malfunction and might invalidate
the CD changer’s warranty and void your FCC
authorization to operate it.
Precautions for Use
• CDs that this changer can play have this mark on
them:
• The CD-9400 has a wide dynamic range. As a result, if
you turn your amplifier’s volume up too high during
low-volume sections of a program, you might damage
your speakers when a sudden loud passage is
produced.
• During play, if the changer is subjected to a sudden
shock or jolt, the CD’s rotation speed might suddenly
change, causing the changer to momentarily become
silent. This is not a malfunction.
• If you move the changer, be sure the CDs has been
removed. This prevents possible damage to the CDs.
• Do not move the changer suddenly from a very cold
room into a warm room. This can cause moisture to
condense on the pickup lens, preventing proper CD
play. If this happens, wait at least 30 minutes before
resuming play.
• Do not place foreign objects in the CD slot. Doing so
can damage the CD changer.
CD Care Tips
Even though a CD is very durable, you should handle it
with care.
• Keep the CD inside the CD changer or in its protective
case or sleeve when you are not playing it.
• Handle a CD by its edges to avoid fingerprints which
can prevent the CD changer’s laser beam from
accurately reading the CD. Your local RadioShack store
sells a suitable CD cleaner kit.
• Do not write on either side of the CD, particularly the
non-label side. (Signals are read from the non-label
side.)
• Keep the CD dry. A water drop can act as a lens and
affect the laser beam’s focus.
If a CD skips or the CD changer displays U1 when you try
to play it, it might be scratched. Your local RadioShack
store sells a Scratch ‘n Fix kit that might help remove the
scratch and stop the skip. See also “Troubleshooting” on
