29 Tempest®2400 2-Channel Wireless Intercom System
Maximizing System Performance and Operaonal Range
Radio waves (especially those at 2.4GHz) can be signicantly aected by walls, windows, or other physical barriers.
Concrete or metal walls can be of parcular concern. Some nted windows are also signicant barriers to RF. Always
posion antennas to minimize interference from all barriers.
A human body can be a barrier to the radio signal, especially when operang near the limit of the signal’s range. If you
experience interference, turn the BeltStaon toward the BaseStaon antenna.
Electronic equipment can generate radio interference. Install the BaseStaon 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 BeltStaon.
Reected RF signals, called mul path interference can cause inter symbol interference resulng in compromised audio.
Mul path interference should be suspected when audio is imperfect and there is no other obvious cause. Typically,
inter symbol interference requires a reecon path that is at least a few hundred feet. It is most likely to occur in a large
enclosed venue with highly reecve walls or ceiling. If inter symbol interference is suspected, relocate the BaseStaon
antenna and/or try a direconal antenna to help eliminate received reected signals.
Line-of-sight operaon between the BaseStaon antenna and the BeltStaons will always produce the maximum system
performance and operaonal range. Minimize obstrucons between the BaseStaon antenna and the BeltStaons when
possible.
Use an oponal direconal antenna to improve system performance and operaonal range. A direconal antenna focuses
the RF signal into a smaller area. When the BeltStaon 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.
