The supervised edge system is capable of communicating in either of two channels, A or B. Each unit is set to the default communication 
channel A from the factory. Under most conditions the factory setting will not have to be changed. When two systems are used in close 
proximity (less than 6 feet), one system should be set to channel B.

To select Channel B the rear covers of both units must be removed and the jumpers marked in the following illustration must be placed 
over both pins. To select Channel A the jumper should be placed over one of the pins securing it for storage.
