The maximum operating distance between the transmitter and receiver is about 46 meters (150
feet). The operating range will vary in different buildings and surroundings. In some locations,
the signal may momentarily disappear. This is called a “drop-out” and is due to reflection and
cancellation of the radio signal. Moving a few feet should restore the signal.
Keep the transmitter and receiver units at least 1 meter (3 feet) apart. If the transmitter gets
too close to a receiver, it may overload the receiver, causing noisy reception or blocking of the
signal.
Do not use more than one transmitter on the same channel (frequency) at the same time unless
they are physically separated by more than 60 meters (200 feet). Operating more than one
transmitter on the same channel at the same time in the same place will result in interference.

:
For multiple tour groups within the same facility, multiple Tour Guide Systems may be oper-
ated on the same channel at the same time by maintaining physical separation of more than 60
meters (200 feet) between groups. The physical separation of groups takes advantage of the
FM capture effect which causes receivers to lock onto the closest transmitter.
