The effective areas of
the transmitter
The optimum distance is up to approximately
100 m without the system picking 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 the transmitter unit and the
headphones, or select the other channel.
Notes
• When you use the headphones inside the effective
areas of the transmitter, the transmitter can be placed
in any direction from the listener.
• Even within the signal reception area, there are some
spots (dead spot) where the RF signal can not be
received. This characteristics is inherent to RF signals,
and does not indicate malfunction. By slightly moving
the transmitter, location of the dead spot can be
changed.
