AV7900 Owner's Manual
Using The Wireless Headphones
The system comes with infrared (IR) wireless fold-flat headphones.
These headphones receive a signal from an IR transmitter built into the
unit. Headphones allow rear-seat passengers to listen without using
the vehicle speakers.
To turn the headphones on and off, push the Power ON/OFF button on
the earpiece. The Power LED on the earpiece indicates when head-
phone power is on. Power turns off automatically after three minutes of
no audio, in order to preserve battery life.
The headphones have a two-position slide switch labeled "A/B." When
the switch is in the "A" position, the headphones play audio from the
source designated as "A." When the switch is in the "B" position, the
headphones play audio from the source designated as "B."
To adjust the headphone volume, rotate the thumb wheel on the head-
phones.

replace the batteries, slide off the battery compartment door on the left
earpiece and insert batteries, as shown. Make certain that the battery
orientation matches the marks inside the battery compartment.
