Problem
The remote control does
not work.
After stopping the player,
I push Play but
sometimes the DVD
starts where I left off and
sometimes at the
beginning.
3-98
Recommended Action
Check to make sure
there is no obstruction
between the remote
control and the
transmitter window.
Check the batteries to
make sure they are not
dead or installed
incorrectly.
The parental control
button might have been
turned on. The power
indicator light will flash.
If the stop button was
pressed one time, the
DVD player will resume
playing where the DVD
was stopped. If the stop
button was pressed
two times the DVD player
will begin to play from the
beginning of the DVD.
Problem
The auxiliary source is
running but there is no
picture or sound.
My disc is stuck in the
player. The Load/Eject
button does not work.
Sometimes the wireless
headphone audio cuts
out or buzzes.
Recommended Action
Check that the DVD
player is in the auxiliary
source mode.
Check the auxiliary input
connections at both
devices.
Turn the DVD power off,
then on, then press the
load/eject button on the
DVD player.
Do not attempt to forcibly
remove the disc from the
DVD player. This could
permanently damage the
disc and DVD player.
Check for obstructions,
low batteries, reception
range, and interference
from cellular telephone
towers or by using your
cellular telephone in the
vehicle.
Check that the
headphones are facing
the front of the vehicle.
