Use the car battery adaptor (supplied) to supply power from the cigarette lighter socket 
to the player. The adaptor is for a 12V car battery. Do not use it with a 24V car battery. 
The adaptor is also for use with negatively grounded cars. Do not use it with cars 
grounded positively.

z Hint
If the car adaptor interferes with car operation, use a commercial cigarette lighter extension cord.

• Do  not use the car adaptor if it has been dropped or damaged.
• Arrange the cord so as not to interfere with the driver. Also, do not place the LCD panel where 

the driver can watch.

• If  the picture is not clear, keep the player away from the car battery adaptor.
• Use the car battery adaptor with the car engine running. If it is used with the car engine off, the 

car battery may become unusable.

• If  the  cigarette lighter socket is dirty with ash, etc, a bad connection may cause the plug to heat 

up. Always clean well before use.

• The car battery adaptor may heat up while charging or after a long period of use. That is not a 

malfunction.

After turning the player off, disconnect the car battery adaptor from the cigarette lighter 
socket.

• The  battery indicator does not appear on the screen when the AC adaptor is used or when 

inputting from external sources.

• Charging times may differ from that indicated above due to conditions of use, environment, and 

other factors. The recommended charge up surrounding temperature is in the 10-30°C range.

• Do  not turn off the car engine while the player is turned on. Doing so stops the power supply and 

may cause damage to the player.

• Disconnect the car battery adaptor after use. Since some cars supply power to the cigarette lighter 

socket even when the engine is turned off, the car battery may discharge over time.

• When disconnecting the car battery adaptor, hold the plug to pull it out.
• When listening to the car radio, disconnect the car battery adaptor from the cigarette lighter 

socket to avoid noise.
