Maximizing System Performance and Operati onal Range
Radio waves (especially those at 2.4GHz) can be signifi cantly aff ected by walls, windows, or other physical barriers.
Concrete or metal walls can be of parti cular concern. Some ti nted windows are also signifi cant barriers to RF. Always
positi on antennas to minimize interference from all barriers.
A human body can be a barrier to the radio signal, especially when operati ng near the limit of the signal’s range. If you
experience interference, turn the BeltStati on toward the BaseStati on antenna .
Electronic equipment can generate radio interference. Install the BaseStati on 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 BeltStati on.
Refl ected RF signals, called multi path interference can cause intersymbol interference resulti ng in compromised audio.
Multi path interference should be suspected when audio is imperfect and there is no other obvious cause. Typically,
intersymbol interference requires a refl ecti on path that is at least a few hundred feet. It is most likely to occur in a large
enclosed venue with highly refl ecti ve walls or ceiling. If intersymbol interference is suspected, relocate the BaseStati on
antenna and/or try a directi onal antenna to help eliminate received refl ected signals.
Line-of-sight operati on between the BaseStati on antenna and the BeltStati ons will always produce the maximum system
performance and operati onal range. Minimize obstructi ons between the BaseStati on antenna and the BeltStati ons when
possible.
Use an opti onal directi onal antenna to improve system performance and operati onal range. A directi onal antenna focuses
the RF signal into a smaller area. When the BeltStati on is located within this focused area of energy, it will have a more
powerful signal, which will improve range.
Only use approved antennas. Unauthorized antennas may be illegal.
