Operating Precautions
<Your 54420 will perform well over a long period of time through correct handling and care.>
Notes on Operation
•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.
