blinds to shut out the direct sunlight, or use the MZ7TFT away from the
sunlight.

•SOURCE
SOURCE (AV1/AUX AV IN):
IR AUDIO (AlB/OFF):
If there is more than one (1) MZ7TFT in use
simultaneously, each headphone must
be setto receive on adifferent

MZ7TFT
channel, and each MZ7TFT must be set to transmit on the same
channel as the headphone (Le., left seat monitor/headphones set to
channel Aand right seat monitor/headphones set to channel B). This
will prevent interference of audio by the IR signal being transmitted
from two monitors on the same channel. This is inherent in Infrared
Ray communication and does not mean there is aproblem with the
MZ7TFT itself.
