Replacing the lithium battery
Under normal conditions, the battery will last
approximately 1 year. (The service life may be
shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the
card remote commander becomes shorter.
Replace the battery with a new CR2025 lithium
battery. Use of any other battery may present a
risk of fire or explosion.
Notes on the lithium battery
• Keep the lithium battery out of the reach of children.
Should the battery be swallowed, immediately
consult a doctor.
• Wipe the battery with a dry cloth to assure a good
contact.
• Be sure to observe the correct polarity when
installing the battery.
• Do not hold the battery with metallic tweezers,
otherwise a short-circuit may occur.
WARNING

Additional Information
Precautions
• If your car has been parked in direct sunlight,
allow the unit to cool off before operating it.
• Power aerial will extend automatically while
the unit is operating.
Moisture condensation
On a rainy day or in a very damp area, moisture
condensation may occur inside the lenses and
display of the unit. Should this occur, the unit
will not operate properly. In such a case, remove
the disc and wait for about an hour until the
moisture has evaporated.
To maintain high sound quality
Be careful not to splash juice or other soft drinks
onto the unit or discs.
Notes on discs
• To keep a disc clean, do not touch its surface.
Handle the disc by its edge.
• Keep your discs in their cases or disc
magazines when not in use.
• Do not subject discs to heat/high temperature.
Avoid leaving them in a parked car or on a
dashboard/rear tray.
• Do not attach labels, or use discs with sticky
ink/residue. Such discs may stop spinning
when used, causing a malfunction, or may ruin
the disc.
• Do not use any discs with labels or stickers
attached.
The following malfunctions may result from
using such discs:
– Inability to eject a disc (due to a label or
sticker peeling off and jamming the eject
mechanism).
– Inability to read audio data correctly (e.g.,
playback skipping, or no playback) due to
heat shrinking of a sticker or label causing a
disc to warp.
• Discs with non-standard shapes (e.g., heart,
square, star) cannot be played on this unit.
Attempting to do so may damage the unit. Do
not use such discs.
• You cannot play 8 cm CDs.
