Operating Precautions
<Your 54420 will perform well over a long period of time through correct
handling and care.>
• For your safety, play only at volume levels that allow outside sounds to
be heard.
• Use only audio compact discs.
This player can only play compact discs
bearing the logo shown to the left.
• Do not insert anything other than a CD into
the disc slot.
Do not insert any foreign objects, such as
coins or credit cards, into the disc slot. Be
especially watchful of children’s mischief in
this regard.
• Avoid severe mechanical shock.
When the player is subjected to severe
vibration while traveling over a rough
surface, playback may be intermittent.
When a situation like this occurs, resume
playback after returning to a smoother
road.
• About dew condensation
In cold or rainy weather, just as the interior
glass surface gets fogged, dew (water
condensation) may also settle on the deck.
When this occurs, disc playback may
become intermittent or impossible.
Dehumidify the air in the vehick for a while
before resuming playback.
• Cleaning the disc slot
The disc slot tends to get dusty. Clean it
occasionally to prevent accumulated dust
from scratching the discs.
