maximum 24 feet line of sight , it is recommend that you place the
transmitter base facing where you will be sitting while watching
TV and make sure that the battery housings are fully plugged in to

unobstructed view of the transmitter front while watching TV and
using the headphones. The signal does not transmit through objects!
Do not face the transmitter towards a window or glass sliding door,
as the infrared ray may escape through the window or door instead
of reflecting around the room. If the headphone is placed too far from
the transmitter, a hissing noise may occur. This is a characteristic
of infrared systems and does not mean that the system is defective,
Move closer to the transmitter and or move to a darker area.
