TOUR GUIDE GROUP SEPARATION

HINTS FOR USING THE SYSTEM

Normal operating distance between the transmitter and receiver is about 30 meters. The operating

range will vary in different buildings and surroundings. In some locations, the signal may momentar-

ily disappear. This is called a “drop-out” and is due to reflection and cancellation of the radio signal.

Moving a few feet will restore the signal.

Keep the transmitter and receiver units at least a meter apart. If the transmitter gets too close to a

receiver, it can 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 30 meters. Operating more than one transmitter on the same

channel at the same time in the same place will result in interference.

USING MULTIPLE SYSTEMS FOR MULTIPLE GROUPS:

For multiple tour groups within the same facility, multiple Tour Guide Systems may be operated on

the same channel at the same time by maintaining physical separation of 30 meters between groups.

The physical separation of groups takes advantage of the FM capture effect which causes receivers to

lock onto the closest transmitter.
