Maximizing System Performance and Operational Range
Radio waves can be signicantly affected by walls, windows, or other physical barriers. Concrete or metal walls can be of particular concern.
Some tinted windows are also signicant barriers to RF. Always position antennas to minimize interference from all barriers.
A human body can be a barrier to the radio signal, especially when operating near the limit of the signal’s range. If you experience interference,
turn the BeltStation toward the BaseStation antenna.
Electronic equipment can generate radio interference. Install the BaseStation antenna away from sources of electrical interference. Be aware of
the presence of nearby electronic equipment that may cause interference as you move about while wearing the BeltStation.
Reected RF signals, called multi path interference can cause inter symbol interference resulting in compromised audio. Multi path interference
should be suspected when audio is imperfect and there is no other obvious cause. Typically, inter symbol interference requires a reection path
that is at least a few hundred feet. It is most likely to occur in a large enclosed venue with highly reective walls or ceiling. If inter symbol
interference is suspected, relocate the BaseStation antenna and/or try a directional antenna to help eliminate received reected signals.
Line-of-sight operation between the BaseStation antenna and the BeltStations will always produce the maximum system performance and
operational range. Minimize obstructions between the BaseStation antenna and the BeltStations when possible.
Use an optional directional antenna to improve system performance and operational range. A directional antenna focuses the RF signal into a
smaller area. When the BeltStation is located within this focused area of energy, it will have a more powerful signal, which will improve range.
Note: Directional antennas are currently not available for 900 MHz Tempest models.
Only use approved antennas. Unauthorized antennas may be illegal.
