Remote Control
To use the remote control, aim it at the transmitter
window at the rear of the RSE overhead console
and press the desired button. Direct sunlight
or very bright light may affect the ability of the RSE
transmitter to receive signals from the remote
control. If the remote control does not seem to be
working, the batteries may need to be replaced.
See "Battery Replacement" later in this section.
Objects blocking the line of sight may also affect
the function of the remote control.
If a CD or DVD is in the Radio DVD slot, the
remote control power button can be used to turn
on the video screen display and start the disc. The
radio can also turn on the video screen display.
See Radio with CD and DVD on page 294
for more information.
Notice: Storing the remote control in a hot
area or in direct sunlight may damage it,
and the repairs will not be covered by your
warranty. Keep the remote control stored in a
cool, dry place.
