INTERFERENCE
Unique Identifier
At the factory, each Listener and Talker Unit in the same system is
programmed with a unique identifier so that only the units in that system
will connect with each other. There can be many systems operating in the
same area without interfering with each other.
RF Interference
If there is severe RF interference, complete recovery from the interference
can be obtained by the following three steps:
• Check all Talker Units: turn on any whose green light has gone off
or is blinking.
• Turn the Listener Unit off and back on again to reconnect all units.
• A solid green light on all units indicates reconnect. The units should
reconnect in eight seconds or less.
OPERATING DISTANCE
Under line-of-sight conditions out in the open, the units may operate over a
distance of 150 feet or more. Indoors, where there are reflections, the
units should maintain communication over a distance of 15 to 20 feet even
if the Listener and Talkers occasionally turn their backs to each other.
OTHER USES
• TV—Place a Talker Unit near the TV speaker
• Air, train or automobile travel
• Lectures—Ask the lecturer to wear a Talker Unit
