Troubleshooting
The optimum distance is up to approximately 30 feet
without the systempicking up some interference. However,
the distance may vary according to the surroundings and
environment. If the system picks up some noise while
using it within the above mentioned distance, reduce the
distance between thetransmitter unit and the headphones,
or select anotherchannel.

areas of the transmitter, the transmitter can be placed
in any directionfrom the listener.
Even within the signal reception area, there are some
