Notes
• If you use the headphones at too great a
distance from the transmitter, you may hear a

mean that there is a problem with the unit
itself.
• Do not cover the infrared sensors with your
hands or hair.
• The infrared rays will not penetrate walls or
opaque glass, therefore, be sure to stay within
sight of the transmitter.
