Public IR Usage
On the top of the headset (receiver) there
is a switch labeled "HOME/AWAY." When
using the headset to listen to the television with
the included base, set switch to "HOME." For
use with public infrared systems, set the switch
to "AWAY."
Volume Control
There is a volume control wheel on the top of
the headset where the volume may be controlled
easily. Turn the wheel in the direction of the
"+" to increase volume and toward the "-" to
decrease the volume. See Figure 19 on page 13.
Note: The volume may or may not be affected
by the television volume controls. Please refer
to the television manual or manufacturer for
more information.
Powering On
When the headset arms are extended, the unit
automatically powers on. See Figure 16. When
the headset is removed from the head, the arms
will return to the "off" position. If there is no
audio signal being detected by the C120 for
ninety (90) seconds, it will power down.
Note: The infrared sensor that communicates
with the transmitter base is on the front of the
headset and should remain within sight of the
C120 base. See Figure 17.
