Chevrolet 2005 Uplander Owner's Manual page 249

The headphones will shut off automatically to save the
battery power if the RSE system is shut off or if the
headphones are out of range of the transmitters for more
than three minutes. The transmitters are located next
to the DVD faceplate. If you move too far forward or step
out of the vehicle, the headphones will lose the audio
signal.
DVD and auxiliary audio will always be found on
channel (CHA or CH1) of the wireless headphones.
RSA audio is dedicated to CHB or CH2 of the wireless
headphones.
To adjust the volume on the wireless headphones, use
the volume control.
Notice: Do not store the headphones in heat or
direct sunlight. This could damage the headphones
and repairs will not be covered by your warranty.
Keep the headphones stored in a cool, dry place.
If there is a decreased audio signal during CD, MP3, or
DVD play, there may be a low hissing noise through
the speakers and/or headphones. If the hissing sound in
the wireless headphones seems excessive, make
sure that the headphone batteries are fully charged.
Some amount of hissing is normal.
Both sets of rear seat headphones may include foam
ear pads that can be replaced.
Foam ear pads on these headphones may become
worn or damaged. The headphone foam ear pads can
become damaged if they are not handled or stored
properly. If the foam ear pads do become damaged or
worn out, the pads can be replaced separately from
the headphone set. It is not necessary to replace
the complete headphone set.
The headphone replacement foam ear pads can be
ordered in pairs. See your dealer for more information.

1. Loosen the screw on the battery compartment door

of time, remove the batteries, and keep them in a cool,
dry place.
