  Data Transmission Notes 
 
  There are many factors that will effect transmission ranges and data 
errors.  Below are some guidelines that will help minimize data errors 
and maximize range. 
 
 
   1) Provide a clear +5V power to transceiver 
   2) Use a 18 gauge or better ground connection to the transceiver  
       ground pins. 
   3) Mount transceiver with the highest line of sight view to the 
       other transceiver. 
   4) Use the Rf signal level output to notify your system when the signal 
        strength drops below usable levels.
