• Do not expose the set, CDs or
tapes to humidity or rain, sand or to
excessive heat caused by heating
equipment or direct sunlight.
The mechanical parts of the set
contain self-lubricating bearings and must not be oiled or
lubricated!
You can clean the set with a soft,
slightly dampened chamois leather.
Do not use any cleaning agents as
they may have a corrosive effect.
TAPE decks
To ensure a good recording and
playback quality, clean the head
®, the capstans (B) and the
rubber pressure rollers (c) after
approx. 50 hours of operation.
• Use a cotton ball slightly
moistened with alcohol or a special
head cleaning fluid.
Note: Cleaning of the heads ® can also be done by playing a
cleaning tape through once.
CD player and CD handling
' The lens may cloud over when the set is suddenly moved-from cold
to warm surroundings. Playing a CD is then not possible. Leave the
set in a warm environment until this moisture evaporates.
• To take the CD out of its box easily, press the
center spindle while lifting the CD.
• Always pick up the CD by the edge and put it
back in its box after use.
• To clean the CD, wipe in a straight line
from the center towards the edge using a soft,
lint-free cloth. A cleaning agent may damage
the CD!
• Never write on a CD or attach any sticker to it.
This set is designed for normal CDs. Therefore, do not use any
accessories like CD stabilizer rings or CD treatment sheets, etc. as
offered on the market because it may cause a jamming of the CD
changer mechanism.
