29 Tempest®24 00 4-Channel Wireless Intercom System
Maximizing System Performance and Opera onal Range
Radio waves (especially those at 2.4GHz) can be signi cantly a ected by walls, windows, or other physical barriers.
Concrete or metal walls can be of par cular concern. Some nted windows are also signi cant barriers to RF. Always
posi on antennas to minimize interference from all barriers.
A human body can be a barrier to the radio signal, especially when opera ng near the limit of the signal’s range. If you
experience interference, turn the BeltSta on toward the BaseSta on antennas.
Electronic equipment can generate radio interference. Install the BaseSta on antennas 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 BeltSta on.
Refl ected RF signals, called mul path interference can cause intersymbol interference resul ng in compromised audio.
Mul path interference should be suspected when audio is imperfect and there is no other obvious cause. Typically,
intersymbol interference requires a refl ec on path that is at least a few hundred feet. It is most likely to occur in a large
enclosed venue with highly refl ec ve walls or ceiling. If intersymbol interference is suspected, relocate the BaseSta on
antennas and/or try direc onal antennas to help eliminate received refl ected signals.
Line-of-sight opera on between the BaseSta on antennas and the BeltSta ons will always produce the maximum system
performance and opera onal range. Minimize obstruc ons between the BaseSta on antennas and the BeltSta ons when
possible.
Use op onal direc onal antennas to improve system performance and opera onal range. A direc onal antenna focuses
the RF signal into a smaller area. When the BeltSta 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.
