Battery Replacement
To change the remote control batteries, do the
following:

located on the bottom of the remote control.
2. Replace the two AA batteries in the
compartment. Make sure that they are
installed correctly, using the diagram on the
inside of the battery compartment.
3. Close the battery door securely.
If the remote control is to be stored for a long
period of time, remove the batteries and keep them
in a cool, dry place.

No power.
The picture does not fill
the screen. There are
black borders on the
top and bottom or on
both sides or it looks
stretched out.
In auxiliary mode, the
picture moves or scrolls.
The remote control

After stopping the player,
I push Play but

sometimes at the
beginning.
Recommended Action
The ignition might not be
turned on or in accessory.
