Appendix B:  Optimum RF Reception Guidelines 
Many factors can affect the reliability of RF communication between an 
RF gateway and an RF device. While an effort has been made to 
determine operating specifications, some specifications are not constant. 
RF Communication can be limited by several factors including but not 
limited to EMI (electromagnetic interference), intervening objects, 
antenna orientation and receiver placement. To obtain maximum 
reliability and performance, some basic rules for installing RF 
transceivers are listed below. 
Minimize Interference 
RF reception range can be hindered by spurious EMI noise that may 
interfere with or mask the desired frequency, thereby reducing useable 
range. EMI is generated by any electrical device at various RF noise 
levels depending on the device. Sources of EMI include computers, video 
equipment, digital processors, lighting dimmers, lighting ballasts, motors 
or any large AC source. Every effort should be made to separate any RF 
transceiver from these sources of RF noise including Audio Visual 
equipment in racks. If a gateway must be installed in an equipment rack, 
make sure you have ample separation between the equipment and the 
gateway. 
Gateway Placement 
Optimum reception for any RF transceiver is obtained by installing the 
gateway transceiver in an open area or shelf with a clear line of sight (no 
obstructions between gateway and receiver). Crestron recommends that 
the gateway is at least five to six feet high for best results. Avoid placing 
transceivers or transmitters at a low height or on the ground. Placing RF 
equipment near metal objects, walls, corners or metal enclosures will 
compromise RF propagation and reception. Try to avoid installing 
gateways in equipment racks, service rooms, electrical closets or in 
rooms other than that which the panel is located.
