2007 GMC Envoy Owner's Manual - Page 282

When using the wired headphones, if the front seat passengers play a CD in the Radio with Six-Disc CD (if equipped) or use XM™ Satellite Radio Service (if equipped), you will hear the audio for these sources, instead of the DVD or CD that is currently playing through the RSE. 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. 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. Battery Replacement To change the batteries, do the following: 1. Loosen the screw on the battery compartment door located on the left side of the headphone earpiece. 2. Replace the two AAA batteries in the compartment. Make sure that they are installed correctly, using the diagram on the inside of the battery compartment. 3. Tighten the screw to close the compartment door. If the headphones are to be stored for a long period of time, remove the batteries and keep them in a cool, dry place. 282
